Description Vladimir 2014-11-11 21:24:01 UTC
After a recent upgrade from x11-drivers/xf86-video-nouveau-1.0.10 to 
x11-drivers/xf86-video-nouveau-1.0.11 OpenGL programs stopped working.
For example, in 'glxgears' the gears do not turn. The same happens to another applications -- the image stands still.

Everyghing works fine after the downgrade to v.1.0.10, but not with 1.0.11.

Probably emerge --info and some Xorg logs would be useful. Also would be interesting to know if some error is shown when trying to run glxgears for example

After today's kernel upgrade to 3.18.3 and the xf86-video-nouveau-1.0.11, glxgears do show the rotating gears, but the typical FPS value is 60.
With xf86-video-nouveau-1.0.10 it was typically about 750 FPS.
Comment 3 Pacho Ramos gentoo-dev 2015-01-22 12:02:47 UTC
But, how do games perform on it? glxgears FPS was never an "objective" measure of performance

Also, try to downgrade now with that same kernel the older version to try to allocate the change

I do not have any games installed, so I even do not know what tool to test it with.

I have just downgraded back to 1.0.10, and now glxgears shows 750FPS.

I usually try with etracer (games-action/extreme-tuxracer)

Yes! I hav just checked it, and indeed this is the case! My laptop has vertical refresh rate of 60 frames per second. So it is exactly set up for my screen.
So, everything seems to work fine now.
Thank you!
