Dell Mini 10 with GMA500 (Poulsbo) at 1366x768 under Ubuntu 9.04

I recently acquired my new Dell Mini 10 with the beautiful and bright 1366 x 768 HD 10.1" screen. However, to get the nice HD screen, I had to order the laptop with Windows XP Home pre-installed.

My first order of business was to get the netbook running a dual boot configuration with Ubuntu and Windows. Once I determine that all the hardware works as expected under Ubuntu, I'll be removing windows completely. 

This tutorial assumes that you have a working, fully updated install of Ubuntu 9.04 (Jaunty Jackalope) running on your Dell Mini 10 (not the Mini 10v) and just need to get the Poulsbo driver working for the Intel GMA500. 

Step 1:

Add the ubuntu-mobile PPA to your software sources, install the keys, and update the list:

sudo touch /etc/apt/sources.list.d/ubuntu-mobile.list
sudo echo "deb http://ppa.launchpad.net/ubuntu-mobile/ppa/ubuntu jaunty main" >> /etc/apt/source.list.d/ubuntu-mobile.list
sudo echo "deb-src http://ppa.launchpad.net/ubuntu-mobile/ppa/ubuntu jaunty main" >> /etc/apt/source.list.d/ubuntu-mobile.list
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys C6598A30
sudo apt-get update

Step 2:

Install the kernel source and headers and reboot:

The following step may take some time ... be patient ... 

sudo apt-get install psb-kernel-source psb-kernel-headers

Once complete, reboot the system ...

sudo shutdown -r now

Step 3:

Install the psb drivers and reboot:

If you only need 2D graphics, only install the 2D driver.

sudo apt-get install poulsbo-driver-2d

If, for some reason, you need 3D graphics, install the 3D driver and make sure your user is a member of the video group before trying to use them (note: Obviously, you should replace the word username with your actual username in the command below)

sudo apt-get install poulsbo-driver-2d poulsbo-driver-3d
sudo usermod -G video -a username

Reboot the system to see the fruits of your labor:

sudo shutdown -r now

Conclusion and Notes:

Upon rebooting, you should have a nice desktop at the native resolution.

If you tried following other instructions and your system is now booting into Low Graphics Mode and giving you an error similar to 'Failed to load module "Xpsb" (module does not exist, 0)' then your system is having problems loading the psb kernel module. To check/fix this:

1. Drop to the Shell login
2. Run the following command and see if it reports any errors (it should):

sudo modprobe psb

3. Install the kernel sources and headers and reboot:

sudo apt-get install psb-kernel-source psb-kernel-headers
sudo shutdown -r now

Hopefully this will help someone get their Dell Mini up and running with Ubuntu.
