On my intel card, GL apps in fullscreen just show a black screen with current git or 2.7.99.901. Works with 2.7.1.

I'll try to bisect this one.

Comment 4 Hanno Böck 2009-07-10 10:53:27 UTC
bisecting failed, I stepped over compile problems with inbetween versions. I attached reg_dumper output with a fullscreen app and a log with debugging. Hope this helps.

Maybe this is because 2.7.1 uses EXA by default and 2.7.99.x uses UXA by default. How about if you set AccelMethod UXA in xorg.conf with 2.7.1?

What's the mesa version? Can you try mesa 7.5?

This got fixed somewhere between 2.7.99.902 and 2.8.0.
