Previewing Android L on Nexus 7 2012 through MultiROM!

Disclaimer: Before you start anything, you must know that I take no liability for anything that would happen to your device as a result of you following this guide and/or any of the instructions from the links that will follow.

The new Android L (5.0) has been recently announced by Google, and if you own a Nexus 7 2012 tablet, than this is your chance to try the newest version of Android on your device. Please note that this is nothing official, it is just an port from the Android L emulator with the proper Android 4.4 binaries included. Therefore, you should expect frequent force closes, poor performance overall and lots of other problems.


Here are the general steps you need to follow:

1) First of all, the tablet must have an unlocked bootloader, with a custom recovery installed on it. This is a great guide that'll help you achieve that: link.

2) Then, you must install MultiROM, it will allow you to boot multiple ROMs on your tablet so that if you feel Android L is too unstable, you can easily boot the other ROM: link.

3) Finally, download the Android L files and gapps, and flash everything in MultiROM by following these instructions: link.


If you see a .zip file named repacked-something (repacked4.zip at the time of writing this article), then it needs to be flashed in MultiROM, unless the last link states otherwise. Do not follow what other websites or articles say (they are not even giving direct links to the original authors, which is unfair), some of them advise to flash repacked4.zip directly through recovery, that will not work and you risk bricking your device that way.

So that was all I had to say. I am currently running Android L myself, it is unexpectedly stable, I've seen relatively few force closes, but performs poor in terms of speed. There is probably barely any acceleration whatsoever (YouTube videos won't start at all). The animations are probably accelerated at less than even 30 frames per second and with more than several programs in the multitasking menu, you are going to see huge performance issues.

For the apps that are not available (Chrome, Facebook etc): go on Google, and search, for example, "Chrome apk". It will give you the apk for that app, which can be easily installed. Yes, it can be altered/have malicious code injected but.. this is the only way you can get these apps.

Good luck!

Ubuntu Linux on Chromebook: Crouton vs ChrUbuntu, or installing over Chrome OS or dual booting.

For the end of the term at the University, I've decided to bring with me my Chromebook (Samsung Series 5). I am on a computer science degree, so I must sometimes act like I am a power user or at least, have access to ssh, plus a X client. Therefore, it seemed obvious that I sometimes needed to have a desktop environment able to run native applications (e.g java), plus the X thing via ssh. Okay, Chrome OS is somehow able to do ssh and some sort of X server-client thing, because it's still a Linux operating system underneath, but it's not brilliant at that. 

Before starting anything, I need to say that I am not responsible for anything that happens to your computer by following what I will say. You are doing everything on your own responsibility. Everything is specifically designed for Samsung Chromebook Series 5. It might apply to other machines, or it might not. Please check the sources carefully before doing anything.


One vs. another.

Just to make everything clear: 
  • ChrUbuntu is installed on a removable storage, so it doesn't touch the internal storage or alter it.
  • crouton is installed on the internal storage, so it *might* touch the internal storage.

My recommendation is crouton, for a number of reasons I will enumerate in the section designed to it. ChrUbuntu is probably easier to install, and easier to use, but it has some fundamental drawbacks which make it a bit annoying. For crouton, you'll probably need to use the terminal a little bit, but it's really not that much to be afraid of.

However, because ChrUbuntu is installed on a removable storage, all you have to do in order to get rid of it is to format that storage. This is rather easy, and won't affect the existing Chrome OS installation from the internal storage at all. For crouton, there are some commands to run in Chrome OS in order to remove it, because it installed on the internal storage of the Chromebook. This can get risky sometimes, and if something goes wrong, the only way to recover is to get back to the original state of the storage, and that is to wipe everything and set-up as a new Chromebook.

Fortunately, on Samsung Series 5, there is a hardware switch which just turns off developer mode, and so it wipes the internal storage completely. It might be this easy on other Chromebooks also, but I am not sure about this matter. I advise you to search a little more on recovery for your Chromebook before doing anything.


ChrUbuntu.

First off, I tried to install ChrUbuntu. ChrUbuntu is a quite nice thing, it runs, as I have already told, on a USB flash drive or on a SD card, and you basically dual-boot in order to be able to get into Ubuntu. Yes, you need to reboot for that, so you don't have both running on the same time. 

Installation. 

Technically, to get anything working you need to follow everything from (this is the official ChrUbuntu website) (here), except that at point number 4, you MUST replace the command with the one you get from (here), according to your device and according to where you are installing it (USB flash or SD card). That is all.

Note: turning on developer mode will remove everything from the internal storage!

Luckily, it's not a very hard process (even though at first sight is seems so), and it should be easily reversible in most cases. Unfortunately, after a month, my USB drive stopped working (applications were reporting I/O errors when it happened), and after a reboot it failed to boot anymore in ChrUbuntu. I've seen some other people complaining about this, I don't know if it's only the flash drive which has been broken, if it's related to ChrUbuntu, or if something from the operating system got broken. Anyway, Chrome OS was just fine. 

Booting it up.

What I should mention here is how ChrUbuntu is supposed to start. When you first start the Chromebook, you'll get a warning screen with a "scary" face. At this point, you have three options:
  • Wait for about 30 seconds and it will beep two times, and boot Chrome OS.
  • Hit Ctrl + D -> instantly boot Chrome OS.
  • Hit Ctrl + U -> boot Ubuntu.
Nothing that complicated at all. If you hit Ctrl + U and the installation of Ubuntu is not present, than it will beep so that you know that it can't boot.

Good and bad points.

+ Ubuntu runs exactly like on a regular computer.
+ so you can do (almost, look below) anything you would do on any other machine running Ubuntu.
+ the guy who created ChrUbuntu took care of the drivers, everything is working fine (on my machine at least).
+ little or no maintenance to involved, so might be suitable for people not willing to touch the terminal at all.
+ nothing really altered on the internal storage (except when you first turn on developer mode).

- it's only Ubuntu 12.04, not one of the latest versions.
- because it's installed on a USB drive (2.0 is supported only), or on a SD card, it's deadly slow.
- limited to the maximum speed of the medium it's installed on.
- requires a medium of at least 8 GB, about 2 GB will be free after installation.
- has no swap partition, so when you get out RAM...well, Chrome and other applications will eventually crash, or lag being very bad.


Crouton.  

It's a bit more complicated, but the huge advantage is that it runs on top of Chrome OS, and in the same time with Chrome OS. Therefore, it uses the kernel provided by Chrome OS, all the drivers from Chrome OS, and everything else that is provided by Chrome OS, and so everything should be working just fine and it's extremely fast. When I say extremely fast, I mean that it's one of the fastest experiences I've seen to date on a computer running Ubuntu (this is on just 2 GB of RAM and a dual-core Intel Atom processor running at just 1.6GHz!). 

Important here: just don't do the silly thing of installing Xfce instead of Unity. Xfce is just awful. It has the worst interface I've seen, it's not attractive at all, half of the icons are broken etc etc etc. Go for Unity from the beginning. I did the silly thing, and it seems that there are some "traces" from Xfce on my installation of Unity, and it's sometimes annoying, but I can still do whatever I want because I have the terminal available. 

Actually, forget what I said above. Xfce works actually quite well, and it is worth to give it a try. It will be significantly faster than with Unity, but I still think that Unity will give higher productivity. It's really up to you. Please note that you must use "xfce" wherever you see "unity" in this guide, and start it using "sudo startxfce4" after installation.

Installation.

For the installation, follow the first point from ChrUbuntu for your own Chromebook, that is, just to turn on developer mode. I repeat, from (here), follow just the first point!

Then, from (here), download the package provided. 

Afterwards, follow the guide from (here, same as before but at another heading), but for the point 2, type "unity" instead of "xfce". This will install Unity. For point 4), type "sudo startunity", and Unity will start. Everything else is the same.


Note: logging off does not work for me, for some reason. If this is the case for you, to close Unity, just hit Ctrl + Alt + Back to get back to Chrome OS, and then, in the crosh window in which Unity is running, hit Ctrl + C. This is not a very elegant way of closing it, but it should kill it pretty okay.

Starting it up.

Just as with ChrUbuntu, when you power up your Chromebook, you will get the "scary" face warning. But now, you can wait for 30 seconds and Chrome OS will boot automatically, or you can hit Ctrl + D and it will boot Chrome OS at that moment.

When you want to start unity from now on, hit Ctrl + Alt + T. This will open a crosh window on Chrome OS. There, type "shell". Afterwards, type "sudo startunity", just as before, and it should start.

To close it, try to click logoff. If it doesn't work, then go to Chrome OS, and in the crosh window, hit Ctrl + C.

Good points and bad points of this method.

+ it runs on top of Chrome OS, in the same time with it.
+ easily switch between them.
+ everything is guaranteed to work.
+ performance is absolutely astonishing, as everything is optimized for Chrome OS.
+ Unity + my apps apps add up to about 2 GB, leaving around 8 GB of free storage.
+ unified storage, so each OS can easily manage the files.

- it's only Ubuntu 12.04.
- can be a bit too technical for some users.
- in my experience, I had to use the terminal quite a little bit.
- uses internal storage (not excessively much).
- resources are shared, but I could not notice any difference.


Conclusion.

I've seen a lot of people complaining about the Chrome OS not being a complete operating system, about not knowing to do that and that, about being too minimalist and so on. With the possibility of having Linux working on a Chromebook, this completely vanishes. It's definitely not a solution which satisfies anyone, at least not on my machine. I am expecting it to work much better on the Series 5 550, the newer generation of Chromebooks that has the Celeron processor and double the amount of RAM.

However, it transforms the Chromebook into a computer that is capable of handling almost all the tasks a home or a power user would need to perform.


If you have any kind of questions, I will answer them here. I will try to look regularly for this on this particular post. I think that almost anything you would need can be found just by searching on Google, but if you still need help, I am here and I will try to provide it.

mysms SMS application seems to be very promising, brings many useful features over Whatsapp.

A few days ago I've presented you Whatsapp (here), a great messaging app available for a lot of mobile platforms which gives you the possibility to send free messages over the internet to all the users who have Whatsapp installed on their device. One of the disadvantages of Whatsapp is that you must be on your phone to send the messages, so you can't register on your phone and then send the messages from your computer or anything like that.

However, with mysms SMS application, it becomes possible to send messages from your computer to all of your friends from all the other platforms, using the mobile phone number you register with before. Moreover, mysms comes also as a standard SMS client, having the ability to handle all the SMS functionality of your phone's default SMS application. More specifically, you can send and receive standard SMS messages directly through mysms, without having to open the stock application separately (you'll have the option to send messages via mobile carrier or via mysms, in case your friends have it). I don't know whether this works or not on iOS because of Apple's restrictions, but on Android it works quite well.

One problem which I found is that I can't send messages through mysms from the browser (Chrome), maybe this functionality is currently unavailable, but it's still a great product. At 700 messages a month from my carrier contract, I think that it's still worth using it, considering that I don't even need to access my phone in order to view or send messages. And the ICS/JB design is a big plus over Whatsapp.

Visit the official website for more information http://www.mysms.com/, or search directly in App Store/ Google Play for "mysms".

XXLF1 radio for Galaxy Nexus, OK to install (works good).

Yesterday I installed the latest radio available for my GSM Galaxy Nexus, version XXLF1. It works without any problems, didn't occur any signal drops or anything like that. The WiFi signal seems to be the same, while the GSM signal is significantly improved (HSDPA). It's difficult to notice any battery change, but it seem to be slightly improved (30% at the end of the day).

Please note the the beginning "XX" means that this is a radio only for the European networks, so don't try to install it if you live somewhere outside the Europe. It works very good in Romania, didn't have any issues after installing (Vodafone). Tested on Jelly Bean.

Download from XDA: link (flashable zip, flash in CWM recovery). If the link becomes broken, please report in a comment and I will change it.

Make S3 ProSavageDDR graphics card work properly on Windows 7.

Over the last few days I've been using my old Fujitsu Siemens notebook, which runs on an old hardware (it is not worth mentioning its specifications). It had Windows XP installed and after a few crashes and a lot of lagginess, I decided installing Windows 7 on it, hoping it would run better afterwards. So the installation went smooth, but I got stuck at what I was afraid of, the drivers. Almost anything worked out-of-the-box, but in a limited way. For the video card, which I want to talk about, Windows 7 used some sort of basic graphics driver, instead of using a dedicated one, which meant very sluggish graphics and improper resolution (had to find the right one by myself).

Basically, S3 (the company who manufactured ProSavageDDR) dropped the support for this graphic card, along with many others, leaving on their website only links from where you can theoretically download the drivers. Theoretically, because the download links are broken, and now (at the time of writing this article), even the webpage is down. But the main problem is that many of the other download links (from other websites) for the driver for ProSavageDDR are down, broken or link to nowhere, so it is quite difficult to find the driver for this graphics card. Moreover, the support has been dropped when the driver was designed for Windows XP or earlier, so there was no driver for Windows Vista or 7 created. 

However, I managed to find the driver on a website (link posted below), and I even successfully installed it on my laptop and it works more than decent. The idea is that you can first try installing it normally (double click that file), or, if that fails, you must install it in compatibility mode: right click the file -> Properties -> Compatibility -> Check the box from "Run this program in compatibility mode for:" and select "Windows XP (Service Pack 2)". Then, just reboot and you should see at Screen resolution the name of your graphics card. If that happens, it means that everything is OK.

Download link: ProSavageDDR driver (Windows XP and 7, confirmed to work).

We'll probably have an alternative to iOS for the iPad soon, and that's the Chrome OS.

OK, I'm starting by telling that I have no idea about how popular "Hexxeh" is, but I never heard of him until now. And it seems that he isn't very popular on YouTube, as he has only a few thousands of views. But he did something really interesting, he succeeded to run the Chrome OS on the iPad. Yes, I'm sure you know, that OS created for netbooks by Google, running on the so popular iPad. So here's a video of what he did.



This seems to be quite real, because of two reasons: the first one is the pointer, which you can see that really moves when he clicks on something, and the second one is the speed of the OS, which shows that the Chrome OS might have been emulated on that iPad. Of course that there is a lot of job to do for Hexxeh, and one of the first things he needs to do is to improve the speed of Chrome OS (if he wants to release a official version of his work, of course).

How to install Frash (Flash) on your Jailbroken iPad (the easy way).

One of the biggest disadvantages of browsing the web via the iPad is its total lack of Flash, which makes it not that web-friendly. Apple claims that Flash sucks, that it uses enormous resources, that it is slow, it drains battery fast and many others. That's why they probably won't ever accept Flash on the iPad.

Actually, Apple is that one which sucks here, because Android shows that Flash can run decently on smartphones. OK, without counting on what's on YouTube, I can tell you that Nexus One is compatible with 99% percent on what's out there (yes, on the internet), and on over 90% of all websites containing Flash content, Nexus One is capable of playing that content smoothly.

Returning to iPad and Flash, there's a way of installing something like a Flash, named Frash, on it. But firstly, you need to know that you must have a jailbroken iPad. And you can jailbreak it only if you're on iOS 3.2.1 or below (sorry if you're on 3.2.2). For the right firmwares, just use http://jailbreakme.com/ (I hope I don't need to tell you that you're doing it on your own responsibility).

Then, after you finished jailbreaking your iPad, you must start Cydia, go to Manage | Sources, and there add http://repo.benm.at . After you've done that, just search for "Frash" on Cydia. Install it, and, bingo, you have....Flash, on your iPad. You just need to type on what's Flash content on websites in order to display it, but, unfortunately, it isn't as compatible as it should be.

I mean, stuff like ads work perfectly, but where we are talking about games or videos, you'll be disappointed. Mainly, they won't work at all. So, even with this trick, iPad's style of browsing is still far away from where's Android's browser.

iPhoDroid, the simplest way of installing Android on you iPhone, is available for download (Windows).

iPhoDroid is probably a really waited application for lots of iPhone users. It allows now the installation of Android on your iPhone, under Windows operating systems. However, it is not clear if it is compatible with any Windows or with any iPhone, but it should work over XP and Vista (both 32 and 64-bit platforms), and for the 3G iPhone (from what I've seen on YouTube).

I don't know if it works with Windows 7 or not, or for the other models of iPhone, but as long as you haven't found anyway a confirmation that it works with your OS and with your iPhone, I don't recommend you trying this. Moreover, you're doing everything on your own responsibility, so if something goes wrong, you might have to restore your device.

Direct download for official site (please notify me if the link becomes unavailable): iPhoDroid download.

Exclusive: Install Google Earth 1.1 on your Android 2.2 device (without Market) !!

You probably heard that today Google launched "Google Earth", version 1.1 for Android 2.2 devices. It should be normally available for download via the Market (as everywhere writes that) or via a scan of its QR code, but, unfortunately, it isn't. Or at least, I can't find it in the Android Market, and there are many users complaining about this. If you are one of these users, I have a good news for you. I found a way of installing Google Earth on Android, without the use of Market.

We are going to use another application in order to install Google Earth, and app that has similar functionality to the Market. So, open the Android Market, and search, download, and install "AppBrain App Market". In the meanwhile, go to AppBrain.com from your desktop (most recommended) and create an account using your Google account.

When you finished creating your account, open AppBrain App Market, and sign in with your Google account (you should see in the upper right corner "Sign in"). When you have successfully signed in on your account in AppBrain App Market, go again in the Android Market, and download "Fast Web Installer". It will ask after launch for the permission to your Google account, so give it, and then the app will quit by itself.

The following step is to go on your browser from your Android device to AppBrain.com (you should be automatically logged on; if not, login with your Google account), search for "Google Earth", click on the first result, and then click "Install" (not "Download directly from the Android market!). The download will start automatically, and you'll have Google Earth on your device installed in a few moments.

So, enjoy Google Earth and if this really helped you, please share this page with your friends! :-)

Android 3.0 test build already done?

Yesterday, Kevin Krause, an editor from Phandroid presented a photo on the website with a device which seems to be running the Android 3.0. From the photo, we can see that it's a Nexus One (this is what's written in "About"), but it is not known why the upper part of the device has been covered with a sheet of paper.

As some users said, it is a high probability for this photo to be a fake one, as it's easy to modify what's written in "About". However, I think that there's a change for the Android 3.0 to be already released for a small group of Android engineers, for testing/developing purposes.

Anyway, I have to warn you. If you see on the following period a build which claims to be the Android 3.0, don't install it until a confirmation from reliable website in the domain is received. Just be patient, and don't make something you'll regret later. I don't think you want a bricked phone...

More on Phandroid.

What do you think about this photo?

TouchWiz from Samsung working on the Nexus One without root.

Somebody from xda-developers claimed that he ported Samsung's TouchWiz to Android 2.2 for the Nexus One. Even if some users said that this is something great, what I think is that Android's 2.2 default interface looks 10 times better than Samsung's TouchWiz, but this doesn't matter. What is important is that that person worked to do this, so that's why we have to appreciate his work.

He said that it works on the FRF83, so if you're FRF91, I can't guarantee you that it will work. I wasn't able to install it, as the user said that it needs to be installed with adb. It fails to install normally ("There is a problem parsing the package"), and, from what I know, adb means Android Debug Bridge. If I'm right, there's a quite complicated process which needs to be done, but you can try (use Google, it will help you) if you want to.

Ubuntu 10.10 Maverick Meerkat Alpha 2 is available.

I don't know which are your feelings about Ubuntu 10.04, but I have the impression that it was just released. And I have to tell you, that on the 3rd of June, the development for the following version of Ubuntu was officially starting, with the launch of Alpha 1. Today, we already have the Alpha 2, which has been released on the 1st of July. 

You're probably curious to know the changes now. So, they aren't really important....interface was a little redesigned, a change that is even hard to see at a first look, boot time seems to be improved a little...and some bugs related to the sound and booting procedure. The rest is the same.

The schedule has been changed this time. We have 3 Alphas, a Beta, the Release Candidate and the Final Release. So here's the schedule:
  • 3rd of June - Alpha 1
  • 1st of July- Alpha 2
  • 5th of August - Alpha 3
  • 2nd of September - Beta
  • 30th of September - Release Candidate
  • 10th of October - Final release
You can download the current build (Alpha 2) from here.

Testing campaign for BitDefender 2011 Beta has started.

BitDefender, the security company from Romania, announced the start of the testing campaign for their latest security suite, 2011 Beta. The installation of this new product is done quickly, with the possibility of scanning before installation and without the need of restart after installation. What you have to do in order to get this product working, is to enter here to create an account at BitDefender (if you don't have one), and then to enter here and select one of the first two options. Then you'll get two keys, which will give you 180 days (6 months) of trial if they are inserted.

Related to the antivirus itself, it now has another interface which is optimized especially for unexperienced users. It includes "Search Advisor", which automatically warns you if you visit a website reported as infected (all links are automatically checked with BitDefender's servers), a new utility which displays you all applications that are stressing your computer and suggests you ways of fixing them, and a new mechanism, which assures the optimum speed of the computer (the antivirus adapts its use of resources dynamically, depending on the available resources of your computer).

The detection rate has been improved compared to the earlier version (with the help of new methods of detection and upgraded existing ones), and I can really say that this places BitDefender on top of the world's most powerful antivirus suites. However, as usual, BitDefender has important problems related to the fix of advanced and complex malware. This kind of problem can even make your system unable to boot.... so this is an important thing that is not yet resolved.

If you want, you can download and test this security suite, but as it is a Beta 1 version, I don't recommend you using it in an environment in which the security is something essential.

Twitter comes to Ubuntu by default, in Lucid Lynx.


The new version of Ubuntu will be having Gwibber installed, a new social client that allows you to connect to
  • Twitter
  • Flickr
  • StatusNet
  • Qaiku
  • Facebook
  • FreindFeed
  • Digg
  • Identity.ca
Gwibber is already included into Alpha releases of Ubuntu 10.04, and it is a very simple and efficient client. It's easy to be configured, starts fast, moves fast, and it's easy to see your own tweets in the timeline.

Installing Ubuntu on MacBook (via VirtualBox).

Today I have installed Ubuntu (under VirtualBox) on my 13,3" MacBook White. Ahead, I'm going to describe everything you should know, in order to get Ubuntu and Mac OS X on the same MacBook. I want you to know clearly. Ubuntu will run inside Mac OS X, it won't be installed separately. In order to boot Ubuntu, Mac OS X needs to be already booted. They're going to run at the same time.

So, let's get started. First, you need to get VirtualBox from here, and a image of Ubuntu from here (please choose your country). Install VirtualBox like any other application for Mac OS X, and start it. Let the image of Ubuntu like it is.

Now, on VirtualBox, do the following:
  • click "New"
  • click "Next"
  • give it a name and at operating system select "Linux", and at version select "Ubuntu"
  • select an amount of memory to allocate to Ubuntu (do not give it more than your current free RAM memory; 512 MB are really enough if you don't have more) and click "Next"
  • be sure that "Create new hard disk" is selected, and click "Next"
  • click "Next"
  • check "Dynamically expended storage" and click "Next"
  • here just select the size for Ubuntu, and click "Next"
  • now click "Finish"
As you can see, on the left column of VirtualBox, your new Ubuntu appeared. Now do these:
  • click "Start"
  • select "OK"
  • when the window appears, click "Next"
  • now, at the Media Type select "CD/DVD-ROM Device", and at Media Source click on the folder from the right, click "Add", and select the recently downloaded image of Ubuntu. Select it and click "Select"
  • click "Next"
  • click "Finish"
Now the image of Ubuntu is going to be booted automatically. Install it like usually. Don't worry about the partitions, let it install itself on the entire hard drive, because it's a virtual one, made by VirtualBox. None of you data will be affected.

After the installation of Ubuntu is completed, give it the requested reboot. Don't worry if Ubuntu moves hard, it is normal at this moment. Now, on the window of Ubuntu, click on "Devices" (the button is up, on the silver bar), and select "Install Guest Additions". On the window that appeared, select just to open the folder. Now, drag the file named "VBoxLinuxAdditions-x86.run" on the desktop of Ubuntu. Continue by doing the following:
  • on Ubuntu, go to "Applications" --> "Accessories" --> "Terminal"
  • here, on Terminal type: "cd Desktop" (without quotes)
  • type in Terminal: "sudo sh VBoxLinuxAdditions-x86.run"
  • now you have to enter your password (that one you have entered when you installed Ubuntu; type it, and even you don't see anything, it is there; tap enter when done, or if you haven't entered a password, just tap enter)
  • wait for a few minutes
  • when installation is completed (last line is like the line you saw at the start), close the Terminal
If any reboot is requested, accept it. When you are ready, open the Terminal again and:
  • type "sudo gedit /etc/X11/xorg.conf"
  • enter again the password you have entered during installation, and tap enter
  • on the window that has appeared, modify where it says "Modes" with the resolution of your monitor (on my MacBook White 13,3" it is 1280x800)
  • save that file and close it
  • restart the operating system
After restart, Ubuntu should already be running on the selected resolution, on full screen.

Now you can change many settings in VirtualBox (while Ubuntu is shut down), as the video memory allocated to Ubuntu. Be sure not to give it too much, as the operating systems are sharing their resources. For Desktop Effects, 3D acceleration should be enabled, but on my Ubuntu (10.04 Alpha 3), the mouse disappears when the 3D acceleration is on.

So, that's all. Congratulations if you succeed. Your new Ubuntu installation is completed. Enjoy!

P.S: This works also for the installation of Ubuntu under Windows, because all you need to to is 100% the same.
