If you’ve been having problems with Ubuntu 9.04 crashing and can’t seem to figure it out, try the following:

Step 1: Add X-Updates to your Repository List and Update your System

Add X-Updates to your repository list (found here: https://launchpad.net/%7Eubuntu-x-sw…ive/x-updates/ (don’t forget to add the key)

(pictures with more detailed steps coming soon)

The X-Updates repository has “Updated versions of X.org drivers, libraries, etc. for Ubuntu.” So adding this repository will ensure you have the most up to date drivers and libraries which you will need.

Now enter the following in your terminal to update and upgrade your system:

sudo apt-get update && sudo apt-get upgrade

Step 2: Download the Pre-Compiled (for Ubuntu) Kernel v. 2.6.30

Since the 2.6.30 version of the Kernel will not be included in the Default Ubuntu Repositories for Jaunty (9.04) , you will need to download and install it manually…

You need to download the Kernel for either a 32-bit (i386) or 64-bit (amd64) processor. Make sure you know what you have an download the appropriate debs.

If you have a 32-bit (non-64bit) processor, enter the following in your terminal:

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30/linux-headers-2.6.30-020630-generic_2.6.30-020630_i386.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30/linux-headers-2.6.30-020630_2.6.30-020630_all.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30/linux-image-2.6.30-020630-generic_2.6.30-020630_i386.deb

If you have a 64-bit processor, enter the following in your terminal:

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30/linux-headers-2.6.30-020630-generic_2.6.30-020630_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30/linux-headers-2.6.30-020630_2.6.30-020630_all.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30/linux-image-2.6.30-020630-generic_2.6.30-020630_amd64.deb

Or if you prefer you can download them manually through your browser by visiting the following URI: http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30/

Step 3: Install the new Kernel

Now simply run the following command in your terminal to install the new Kernel. Note this works for both 32 and 64 bit versions (no need to modify the command)…

sudo dpkg -i linux-headers-2.6.30-*.deb linux-image-2.6.30-*.deb

Step 4: Restart your System

After you restart your computer, your new kernel should be the default (first) option… Go ahead and boot with it and enjoy! No more crashes!!!
