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
