Ok, this was really helpful. Is this set permanently now, or do I have
to repeat it after restarting X ?

Anyway, I don't get what this has to do with 2D performance... For the
moment 2D performance is back to normal and glxgears (Which is not a
benchmark, yes :) shows 800 FPS.

Thanks a lot.

The fundamental theorem of algebra is open source. Like any other
mathematical theorem it can be applied free of charge and everybody
has access to its proof and can convince himself how it works. Why
should software be any different?
