Kernel log
I am using the latest nouveau git kernel sources on top of 3.7.0-rc3,
xf86-video-nouveau 1.0.3, mesa 9.0, and xorg-server 1.13.0 and a gtx580. The
main issue is that X freezes when the GLXVBlank option is enabled.
The screen freezes up seemingly when any OpenGL stuff gets rendered. Even
running glxinfo can freeze it up, but just starting a basic twm session or i3wm
will not freeze it. Attempting to play movies via xvmc also freezes it, so I
guess it it not purely OpenGL related. It runs fine when vblank is disabled
doing the previously mentioned things. I tried using proprietary firmware as
suggested in IRC but that did not help.
As for the freeze: the mouse starts slowing down and then freezes, and then it
can be moved again but X is completely frozen. I can switch to a different tty
without using SysRq+R. The tty only appears in a small box in the upper left
hand corner and the rest of the screen is what it was when X froze. The tty is
all corrupted too... but you can see text changes when you type, and I can copy
logs and reboot so the system is still mostly working, the graphics are just
completely messed up.</pre>
