Corrupted screen after resume from hibernation
On resume from hibernation, screen is always totally corrupted (I attach a
photo of my screen). If I move the mouse, I can see a square shape moves on the
screen. I can ssh my computer and all seems to run fine (and I can retrieve the
following attached files), but display is broken.
I can switch to terminal with ctrl+alt+Fn : display is still corrupted, but I
can see corruption pattern changes and the square shape disappears.
Graphic corruptions appears during hibernation (just before power down) and
after grub and kernal loading messages.
I use kms.
When my computer is in this state (resumed from hibernation, display
corrupted), I can press power button to enter suspend (on ram) mode :
sometimes, when I wake up from this state, screen corruption disappears.
I don't know if this can help, but if I use suspend (to ram) with
--quirk-no-chvt (which is added by default by pm tools with kms), I have the
same problem. Suspend works fine when I disable all the quirks.
Attached :
* photo of the corrupted screen
* pm-suspend.log (retrieved via ssh after resume)
* dmesg (retrieved via ssh after resume)
* lspci</pre>
