How to install Kernel v3.0 on Ubuntu 11.04

Kernel v3.0 is out there and will be released with Ubuntu 11.10 and yet, there are no kernel updates for Ubuntu 11.04 after Kernel v2.6.38. If you are very eager to install kernel 3.0, then you can build them directly from the source code. Or just use the packages that are used to install Kernel 3.0 on Ubuntu 11.10. Since the latter approach is simple and easy, I will mention step by step instruction to install Kernel v3.0 on your Ubuntu 11.10 Natty Narwhal.

Step 1: Download the debian packages from here.

For 32 bit users -

1. linux-headers-3.0.0-0300rc2_3.0.0-0300rc2.201106081532_all.deb 2. linux-headers-3.0.0-0300rc2-generic_3.0.0-0300rc2.201106081532_i386.deb 3. linux-image-3.0.0-0300rc2-generic_3.0.0-0300rc2.201106081532_i386.deb For 64 bit users - 1. linux-headers-3.0.0-0300rc2_3.0.0-0300rc2.201106081532_all.deb 2. linux-headers-3.0.0-0300rc2-generic3.0.0-300rc2.201106081532_amd64.deb 3. linux-image-3.0.0-0300rc2-generic_3.0.0-0300rc2.201106081532_amd64.deb

Step 2: Once you have downloaded all the files, place them into a single folder. Browse to that folder from your terminal and then copy paste the following code into the prompt.

sudo dpkg -i linux-*

The execution will continue to install kernel 3.0 on your Ubuntu 11.04. Just in case kernel 3.0 mess up, do not remove previous versions. You can always choose from the previous versions in the grub.

If you have or happen to install this, then please comment on the power consumption and other pros and cons of kernel 3.0. 

Install Unity Qt (2D) on Ubuntu 10.10 and 11.04 using PPA

As we all know now, the next version of Ubuntu has a major change in its desktop environment from Gnome to Unity. It was only a little time ago when Unity Desktop was released for Ubuntu 10.10 users could've installed Unity Desktop by sudo apt-get install unity-desktop. But users who had poor graphics support had a hard time coping up with it and  most of them returned to GNome. But now there's a solution as Unity Qt has been released which is the 2D version of the Unity Desktop having minimalist animations and 3D Effects. Unity Qt is lot faster than Unity 3D so I'm sure users are going to enjoy this.

Here's a snapshot of it and it doesn't look that different from the actual 3D Unity.

To install Unity-Qt open your terminal and execute the following instructions in the same order.

sudo add-apt-repository ppa:unity-2d-team/uity-2d-daily

sudo apt-get update

sudo apt-get install unity-2d-default-settings

sudo apt-get dist-upgrade

Next time you log in, select Unity-Qt from the options of Environments.

Hope that helps.
