Im having a bit of a problem with ubuntu. I just installed amd 11.9 driver from the amd website.

Now the boot is stuck at this image. boot fail

How do I resolve the issue without reinstalling Ubuntu? The computer is running Ubuntu 11.10 64bit with an a6-3400m CPU and a 6520g radeon card.

Thanks in advance.

can you access another tty? (press alt+ctrl+f1) –  Bruno Pereira Oct 15 '11 at 19:52

I had all sorts of fun getting the 11.9 driver installed and working. Even using the "additional drivers" didn't work for me. I had the same issue you had as well. In the end I followed the following steps after booting into recovery and remounting, then dropping into netroot prompt:

1) Remove the fglrx and revert configuration:

    sudo sh /usr/share/ati/fglrx-uninstall.sh
    sudo apt-get remove --purge xorg-driver-fglrx fglrx*
    sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri
    sudo dpkg-reconfigure xserver-xorg

2) Follow the manual install guide:

    sudo apt-get install build-essential cdbs fakeroot dh-make debhelper debconf libstdc++6 dkms libqtgui4 wget execstack libelfg0 dh-modaliases
    sudo apt-get install ia32-libs (only if on amd64 as I was)
    sh ./ati-driver-installer-11-9-x86.x86_64.run (choose build deb packages)
    sudo dpkg -i fglrx*.deb
    sudo aticonfig --initial -f

3) Reboot.

That was overkill but it worked like a charm. Even gnome shell is working now (Other than horribly disfigured/skewed horizontal scroll bars and tooltips[sometimes]). Thank you very much. This is the reason I switched to ubuntu. =) –  Roman Oct 16 '11 at 17:39

On my Ubuntu 11.10 (Lenovo g770), I couldn't start the X (LightDM). I tried Catalyst 12.1 drivers. I got some errors about /usr/lib64.

So, I created a symlink and it worked.

ln -s /usr/lib /usr/lib64

If you can access another terminal (press ctrl+alt+f1 keys) type sudo sh /usr/share/ati/fglrx-uninstall.sh.

That is the official driver remover from ATI, after that use the "Additional Drivers" application to install the ubuntu packages.

After you reboot to a clean desktop make sure all the old fglrx packages are gone:

sudo apt-get purge fglrx*

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

After you get to your desktop again use the "Additional Drivers" program but don't enable the post update ones, use the previous version.

I ran the command and it did it's thing and I can access the gui fine. Thanks for that. However is there any way to install that driver? 11.9 specifically? I need it to run gnome shell properly. –  Roman Oct 15 '11 at 20:16

There is issues with some ATI graphics cards using catalyst 11.9 and Ubuntu 11.10 - see the ubuntuforums thread here
