[Bug 94628] Xorg fails to thaw from hibernate with intel errors

--- Comment #7 from JM9 <jhnmlkvch9 at gmail.com> ---
Unfortunately, that is not it. I get a black screen (looks like no backlight)
when I thaw. I can't get the screen to turn on even entering commands blindly.
I was hoping this way of simulating a hibernation (per kernel documentation)
would turn up something. If the unclaimed registers has nothing to do with
hibernation then I'm afraid I don't know how to get any useful info when the
thaw turns up a blank screen.

Any help in trying to retrieve useful info will be appreciated.

journalctl --boot=-1 did not turn up anything suspicious.
