           Summary: [NV50] Resume from hibernate/suspend does not work
           Product: xorg

dmesg log

After ressuming from hibernate or suspend there is a distorted screen.
Emergency keys or ssh from a remote machine does not work. If the hibernate or
suspend command is initiated from a linux console, not from the X session,
resuming works well but after switching to the X session it gets stuck again.

I had this problem with all kernels released since a couple of years. Currently
I have tried 4.10.3-1 and 4.9.15-1-lts that reproduce the problem.

Attached is the kernel log and output of lscpi.

This problem happens randomly about 50% of the time resuming form
hibernate/suspend.
