Thanks to your help, I managed to find a fix (with a little tweak) http://ubuntuforums.org/showthread.php?t=1870917
What I did: sudo mv libGL.so libGL.so.bak sudo ln -s /usr/lib32/fglrx/libGL.so.1 /usr/lib32/libGL.so sudo mv libGL.so.1 libGL.so.1.bak sudo ln -s /usr/lib32/fglrx/libGL.so.1 /usr/lib32/libGL.so.1 The fix didn't stick, so, I moved libGL.so.1.2 and linked it: cd /usr/lib32/ sudo mv libGL.so.1.2 ~/libGL.so.1.2.bak sudo ln -s /usr/lib32/fglrx/libGL.so.1 /usr/lib32/libGL.so.1.2 I'm not sure, but I think it has something to do with ati mobility chip sets, I had to do this fix with my PC which had: Radeon HD 3450. However my other PC with Radeon HD 5450 had no problems. Sheado reported that he had issue with /usr/lib instead of /usr/lib32.
