ATI driver re-install fail

Solution 1:

For 64bit systems before doing anything.

sudo apt-get install ia32-libs

Run each of these, one at the time, if getting any faults ignore it.

sudo sh /usr/share/ati/fglrx-uninstall.sh
sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev*

Remove your xorg.conf file

sudo rm /etc/X11/xorg.conf

Re-install xorg

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

Configure xorg

sudo dpkg-reconfigure xserver-xorg

Reboot:

sudo reboot

After the reboot all the fglrx packages will be gone, you will be using default ones.

Download the newest ATI driver (current version is 12.1)

wget http://www2.ati.com/drivers/linux/amd-driver-installer-12-1-x86.x86_64.run

Once downloaded go to the file location and set it to run as executable

cd /path_of_the_file
chmod 755 amd-driver-installer-12-1-x86.x86_64.run

Use these steps to install

sh ./amd-driver-installer-12-1-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

Solution 2:

The problem is due to a previous manual installation of the driver, that is without building a deb package, and an incomplete uninstall.

No fear!

Since the package building complains that

dpkg-shlibdeps: error: no dependency information found for /usr/share/ati/lib64/libQtCore.so.4 (used by debian/fglrx/usr/lib/fglrx/bin/amdnotifyui).

or, in other cases,

dpkg-shlibdeps: error: no dependency information found for /lib64/libQtCore.so.4 (used by debian/fglrx/usr/lib/fglrx/bin/amdnotifyui).

you can find alternatives to the library in the system, e.g.

locate libQtCore.so.4
locate libQtGui.so.4

and, if alternatives exist, backup the offending library (libraries)

sudo mv /lib64/libQtCore.so.4 /lib64/libQtCore.so.4.orig
sudo mv /lib64/libQtGui.so.4 /lib64/libQtGui.so.4.orig

Finally, create a symlink to the alternatives (in my case: sudo ln -s /usr/lib/x86_64-linux-gnu/libQtCore.so.4 sudo ln -s /usr/lib/x86_64-linux-gnu/libQtGui.so.4 )

Now package building should complete without throwing errors and so its installation.

It has also been reported that if you're trying a simple reinstall of the proprietary driver (e.g. after a kernel upgrade) it can be enough to move /usr/share/ati/lib64 to another backup location and then build the package in the documented way.
