[Nouveau] errors with GeForce GTX 650 Ti and 3 monitors

[Rob Jansen]

Hi,

Using 3 monitors on the GeForce GTX 650 Ti card (2 DVI and 1 VGA) works great out of the box on Fedora 20. However, every couple of days the graphics driver seems to crash. The same thing used to happen when 2 monitors were in use, but that has pretty much stabilized as of late. Does anyone have a stable setup with this card using 3 monitors? Will 3 monitors be supported?

Thanks,
Rob
