Priority: medium Bug ID: 76559 Assignee: dri-devel@lists.freedesktop.org Summary: screen corruption after going from VT to X Severity: normal Classification: Unclassified OS: Linux (All) Reporter: fabio.ped@libero.it Hardware: x86 (IA32) Status: NEW Version: XOrg CVS Component: DRM/Radeon Product: DRI
I have a MacBook Pro with a RV530 with an external Philips 22" monitor connected (the notebook screen is disabled in X). After switching to VT and then coming back to X the screen is corrupted (like if every odd line has an offset). The same happens after suspend. A screenshot doesn't show the problem. I then usually change resolution with the Ubuntu tool (selecting a different resolution and then reapplying the previous one) and that restore the screen.
Attached dmesg and Xorg log after the X -> VT -> X cycle.

--- Comment #3 from Fabio Pedretti fabio.ped@libero.it --- This issue is still reproducible with Ubuntu 14.04 kernel (3.13.0-23.45), before I was using 3.11.0-18.32 (Ubuntu 13.10 kernel).
This annoying issue is possibly not specific to radeon module. The following dmesg ERROR is interesting and may be of help. Maybe it needs a monitor quirk?

Any news on this issue? It is still reproducible with Ubuntu 15.04 kernel: Linux fabio-mac 3.19.0-26-generic #28-Ubuntu SMP Tue Aug 11 14:16:45 UTC 2015 i686 i686 i686 GNU/Linux
Attached updated dmesg.
Let me know if something other is needed.

Possibly, but I think that may not be related, as that doesn’t always happen and maybe be a different issue.
I attach a different dmesg where the crash doesn't happen, but the corruption problem is still present.

--- Comment #7 from Martin Peres martin.peres@free.fr --- Hi,
Freedesktop's Bugzilla instance is EOLed and open bugs are about to be migrated to http://gitlab.freedesktop.org.
To avoid migrating out of date bugs, I am now closing all the bugs that did not see any activity in the past year. If the issue is still happening, please create a new bug in the relevant project at https://gitlab.freedesktop.org/drm (use misc by default).
Sorry about the noise!
