Hardware: AMD 6870 Twin Frozr II (1GB), ASUS 990 chipset
Software: Ubuntu 11.10

Built a new PC from scratch, loaded it with Ubuntu 11.10. It's displaying, but with poor resolution, unable to change, as it says no drivers are installed.

Ubuntu indicates that there are 2 proprietary drivers available to download:

  • ATI/AMD proprietary FGLRX Graphics driver (Post-release update)
  • ATI/AMD proprietary FGLRX Graphics driver

The first won't even finish downloading.

The second downloads and installs, but when I restart the PC as requested it boots up, I see purple in the background, then the video feed just stops with a black screen. I can still hear ubuntu boot up though.

It seems like I just need the latest drivers, googled around and not had much luck. I'm pretty new with Ubuntu, but have basic knowledge. Any potentially helpful information would be welcome.

Press Ctrl+Alt+F1 keys at the purple screen to you can access a terminal, login with your username and password.

Remove all the fglrx traces from your system:

sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev*

Remove your xorg.conf

sudo rm /etc/X11/xorg.conf

Reinstall xorg

sudo apt-get install --reinstall xserver-xorg-core libgl1-mesa-glx:i386 libgl1-mesa-dri:i386 libgl1-mesa-glx:amd64 libgl1-mesa-dri:amd64

Configure Xorg

sudo dpkg-reconfigure xserver-xorg

Reboot:

sudo reboot

You should be back at using the open-source drivers and being greeted with your login screen.

After this install the drivers from ATI.


Download the newest ATI driver (current version is 11.11)

mkdir ~/ATI && cd ~/ATI
wget http://www2.ati.com/drivers/linux/ati-driver-installer-11-11-x86.x86_64.run

If you have a 64 bit system, then install this before anything

sudo apt-get install ia32-libs

Once downloaded set the downloaded file to run as executable

chmod 755 ati-driver-installer-11-11-x86.x86_64.run

Build the packages for Ubuntu 11.10 and install them

sh ./ati-driver-installer-11-11-x86.x86_64.run --buildpkg Ubuntu/oneiric
sudo dpkg -i fglrx*.deb

Once the driver is installed you need to start up a new xorg.conf file with this command

sudo aticonfig --initial -f

Reboot

sudo reboot
