Ubuntu 12.04 LTS and Nvidia GeForce 7025

If you have the GeForce 7025 integrated card then you have problems with Ubuntu 12.04 LTS. This is how to get a usable setup with 3D acceleration.

Boot to the lastest kernel you have and update your system:

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

Then restart the machine and boot using the latest kernel.

If you have already installed some drivers:

sudo apt-get purge nvidia-common nvidia-*

Add Ubuntu X updates and install latest driver:

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update && sudo apt-get upgrade
sudo apt-get install nvidia-current

Once installed, delete the X Window Server configuration file. Don’t worry, it will be regenerated. This is important.

sudo rm /etc/X11/xorg.conf

Finally, restart the computer and get into the BIOS. Find the Chipset configuration and lower the Shared Memory to 128MB (in my case from auto to 128MB), yep, not optimal, not pretty, but otherwise your graphics will be slow as hell.

Now boot to the latest kernel. That’s it.

EDIT: If you get in the dark after a kernel upgrade, you need to rebuild the Nvidia kernel modules installed:

  1. Reboot in the latest kernel. If you have no video at all you can CTRL+ALT+F1 to get into a terminal.
  2. Make sure you have the kernel headers for your current version:
    sudo apt-get install linux-headers-`uname -r`
  3. Reconfigure nvidia-current package:
    sudo dpkg-reconfigure nvidia-current
  4. Reboot:
    sudo reboot

Hope it helps.
