(nouveau driver) NVIDIA G84 8600M problem with resolution

[Israel Dahl]

With nouveau, I cannot change the screen resolution to anything above 640x480.

WORKAROUND: Use the nvidia proprietary drivers to obtain 1690x1050.

The worst part is the lack of a decent resolution.
But unfortunately the bug is still present.
It is related to another earlier bug, but with much worse resolution now

>"For one, I cannot easily change the screen resolution to something useful. arandr produces no nice resolutions."

Could you please specify what resolution precisely you were expecting, and what is the best you can get?

[Israel Dahl (israeldahl)]

Desired Resolution: 1690x1050 (present with proprietary NVIDIA module)
Nouveau resolution: 640x480 (no other choices in arandr)
It is quite hard to work with such a resolution on such a large LCD :)
