Comment 42 for bug 58232

I've just worked this problem through with a friend, and he was having the same issue.

Adding the following entry to xorg.conf under screen fixed the problem.

Option "AddARGBGLXVisuals" "True"

Tested after a reboot and everything worked fine.

I.e.
-----
Section "Screen"
    Identifier "Default Screen"
    Device "NVIDIA Corporation NVIDIA Default Card"
Option "AddARGBGLXVisuals" "True"

Section "Extensions"
    Option "Composite" "Enable"
EndSection
