Comment 6 for bug 529479

I have a similar problem. Quadrapassel doesn't starts normally cause it shows the screen late and works too slow (playing is imposible).

The errors that Terminal provides are:
(quadrapassel:5349): ClutterGLX-CRITICAL **: Unable to make the stage window 0x4a0002b the current GLX drawable
(quadrapassel:5349): ClutterGLX-CRITICAL **: Unable to make the stage window 0x4a00046 the current GLX drawable

Mi video card is:
VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)

In some other bug (572465) someone refers to this problem too, and post a temporaly solution: to run the game by command:
CLUTTER_VBLANK=none quadrapassel

This works, at least, on Intel graphic cards, although Terminal shows this message:
(quadrapassel:5385): ClutterGLX-CRITICAL **: Unable to make the stage window 0x4a0002b the current GLX drawable
(quadrapassel:5385): ClutterGLX-CRITICAL **: Unable to make the stage window 0x4a00046 the current GLX drawable

Aparently, the problems seems to be solved by downgrading to clutter 1.0
