screens never come back from power save mode

[Bishbosh02]

The issue is that my screens never comes back from power save mode.

(the system worked fine before installing Displaylink drivers).

With V5.4 beta I had the same issue so upgrade to 5.5b but the fault changed to my Nvadi Vido driver kept crashing, windows would recover from this issue.

So I upgraded to the latest version of NVIDIA video driver, still have the issue but now have the blank screen again

Control+Alt+Del will bring back the logon screen but if I hit escape it goes blank again, I have to switch users to bring it back.

I have ran the debug tool see file
