I have AMD/ATI Mobility Radeon HD 5430. lshw says HD 5430/5450/5470. I removed the proprietary fglrx driver and it seems to work again:
How to do that: # sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev* # sudo rm /etc/X11/xorg.conf # sudo apt-get install --reinstall xserver-xorg-core xserver-xorg-video- intel libgl1-mesa-glx libgl1-mesa-dri libgl1-mesa-glx:i386 libgl1-mesa- dri:i386 # sudo dpkg-reconfigure xserver-xorg Then reboot the computer.
