After resume the screen is totally corrupted.

Is this still an issue with recent kernel ?
Comment 2 Johannes Obermayr 2011-02-11 10:13:25 UTC
Yes. It is still valid on 2.6.38-rc4.

Bug is still present up to current kernels (I tested up to 3.11 in ubuntu 13.10) - the screen is corrupted after a resume from pm-suspend (suspend to ram). Corrupt means: the screen content appears approx. 3 times over the screen. (Sort of like three tiles).
Also the VT is trashed, I see 3 login prompts :)

However the screen is ok/fixed after I do a pm-hibernate (suspend to disk) and resume from it.

When I used "nomodeset" and let the xorg driver do the mode setting stuff everything worked fine. Unfortunatly the recent xorg drivers have lost their capability to do their own modeset and now I'm stuck with KMS.
