Friendly follow up on this bug.

I have been trying several different configurations and they all have 
there own set of problems.

Nvidia  + wayland = Several apps act weird, Spectacle breaks depending 
on which app is open.

Nvidia + X11 = works good except for when waking the screens from sleep. 
I get a black screen with mouse cursor. I can see when move over the 
password box because the cursor changes, I can type in the password and 
usually login. Sometimes it does lock up and I have to do hard reboot. 
This is a Kwin + X11 problem but from what I read its not going to be 
fixed since they are only focusing on Wayland.

Nouveau + Wayland = same as original problem

I did update the firmware from the back-ports and it fixed the missing 
firmware errors listed earlier, but I still get this "kernel: nouveau 
0000:01:00.0: drm: Disabling PCI power management to avoid bug"


Can I get an update on this.

Regards,

Benjamin
