Ubuntu 2.6.39 kernel and fglrx 8.831

For those 10.10 Maverick users with 2.6.38 or 2.6.39 (64-bit) kernels, you can get fglrx playing nicely together with 1.9.

Unfortunately this new driver does not support 1.10 and that leaves 11.4 users to use the open-source drivers.

Custom build procedure:

  1. Install the latest 2.6.38 or 2.6.39 kernel revision from Ubuntu Mainline.
  2. Download 64-bit 11.3 from AMD
  3. Extract the files from the package:
    sh ./ --extract ati
  4. For 2.6.38 and up, download these patches: makefile_compat.patch and 2.6.38_console.patch
  5. For 2.6.39 support, download this additional patch: 2.6.39_bkl.patch
  6. Check for Big Kernel Lock usage:
    cat /lib/modules/`uname -r`/build/.config | grep -c CONFIG_BKL=y
    If the result of this command is 0, then download no_bkl.patch as well.
  7. then apply them:
    cd ati; for i in ../*.patch; do patch -p1 < $i; done
  8. Build your new ati/fglrx deb packages:
    ./ 8.831 --buildpkg Ubuntu/maverick
  9. Install our newly created deb packages:
    sudo dpkg -i ../fglrx*.deb
  10. If your /etc/X11/xorg.conf is missing you will need to run:
    sudo aticonfig --initial
    and then reboot.

That newly created package should work for the entire 2.6.38 or 2.6.39 series.
