How do I remove ATI/AMD Drivers downloaded from their site? [duplicate]

Solution 1:

Try to completely remove your ATI drivers from your system:

sudo apt-get purge "fglrx.*"

Remove your xorg.conf

sudo rm /etc/X11/xorg.conf

Reinstall xorg completely

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

Re-configure Xorg

sudo dpkg-reconfigure xserver-xorg

Reboot

sudo reboot

You should be greeted with lightdm, this will default everything x the same way a fresh install would.

Remove the drivers, .deb or normal install (if you get a file not found 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

sudo rm /etc/X11/xorg.conf

Reinstall xorg

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

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 open source.

For more information on how to remove / add / replace ATI drivers in your system there is already a very good post with these steps.

If any of these returns errors like file not found or package not found, ignore it.

Run these commands in a Terminal (Ctrl+Alt+T):

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

Here are the release notes for the driver.

As for their instructions, the uninstall:

aticonfig --uninstall

Alternatively, uninstall can be launched with superuser permissions using the following commands as well:

sh ati-driver-installer-x86.x86_64.run --uninstall 
sh /usr/share/ati/amd-uninstall.sh
