Had the same Problem, after installing the fglrx driver i got the rainbow bar in gnome. This worked for me :
sudo /usr/share/ati/fglrx-uninstall.sh # (if it exists) sudo apt-get remove --purge fglrx* sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon sudo apt-get install xserver-xorg-video-ati sudo apt-get install --reinstall libgl1-mesa-glx:amd64 libgl1-mesa-dri:amd64 xserver-xorg-core sudo dpkg-reconfigure xserver-xorg -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/838577 Title: GNOME Shell display problems with FGLRX To manage notifications about this bug go to: https://bugs.launchpad.net/fglrx/+bug/838577/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
