I am guessing that the graphics driver is not playing well with the power management software. Perhaps typing the username and password "in the dark" *may* reactivate the screen, assuming the cursor is at the right position. Hiberbation would take longer to restore (as it loads up from disk, but if you have a SSD it would be relatively fast) - Sleeping is much faster as it just restarts the cpu and everything is still in ram. > > If I have a browser or other app open and close the lid, it restores > quite well on opening the lid again.

I am guessing, this would only turn off the screen (like a physical switch turning power on/off on your screen), and the power management software does not play correctly with that. > > My only solution to date is to CTRL+ALT+F2 su and reboot.
