How to fix “The system is running in low-graphics mode” error?
After yesterday automatic update of Ubuntu 12.04.01 at the first boot I get the message "your system is running in low graphics mode" and i cannot start my desktop normally. The update was mainly for the Xorg (~100 MB) so I guess the problem is there. The only way I'm able to use my Ubuntu now is after I executed the command "sudo cp xorg.conf.failsafe xorg.conf" The side effect is that Unity starts with the 2D version and I'm not able to get the 3D version back. The ATI driver for this graphic card are no longer available so only the open ones can be used. Thanks in advance for any help.
