Re: [Trisquel-users] Trisquel 6.0: screen frozen

[migatheotaku]

I have a GTX 660. Are you using Compiz at all while the freezes occur? If so,  
the problem might be the same issue that I'm having, in that Nouveau support  
for 3D for the 600 series of cards just isn't stable yet.

I'm able to run 3D stuff, but often the screen will corrupt or the GPU will  
lockup, forcing me to have to either hard reboot or use the Magic SysRq key.

The best you might be able to do is minimize any 3D usage until support for  
the 600 series (Kepler) turns more stable.
