Summary: After pm-suspend the second monitor shows garbled output on evergreen card (kms) Product: DRI Version: DRI CVS Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: bugs.xorg@boris64.net

Created an attachment (id=37311) --> (https://bugs.freedesktop.org/attachment.cgi?id=37311) digicam picture of both monitors

After resuming a previous (via pm-suspend) suspended system the second monitor only shows a garbled picture. Running xrandr to switch resolution seems to work, but the picture still ist truncated. This is a kms/multihead configuration.

Used software: Kernel-2.6.35-rc5 latest xf86-video-ati from git latest libdrm from git latest mesa from git

--- Comment #5 from Alex Deucher agd5f@yahoo.com 2010-07-22 08:48:35 PDT --- Does the other monitor work properly if you turn it off and then re-enable it with xrandr (e.g., --off, followed by --auto)?

It even doesn't seem to work after a warm reboot. I only get a test picture (as if there was no connection between monitor and graphic card) when the bios boots up.

I had to hard reset the computer to get a working second monitor again.

--- Comment #9 from boris64 bugs.xorg@boris64.net 2010-07-22 09:42:54 PDT --- Appendix: If i run 'xrandr --output DVI-1 --off' followed by 'xrandr --output DVI-1 --auto' the second monitor switches off and then on again (garbled screen).

Now if i run 'xrandr --output DVI-0 --auto' (happend accidentally first time), monitor one switches to off and the second monitor shows a correct piture again. Huh?! Running 'xrandr --output DVI-0 --auto' afterwards makes monitor one work and monitor two have a garbled picture again.

Will now try that cold boot thing.

...

Does the second monitor enable properly if you cold boot without it attached and then attach it after X has started?

I think Yes. I have to run 'xrandr --output DVI-1 --auto' to get my desktop back, though.

--- Comment #12 from boris64 bugs.xorg@boris64.net 2010-07-24 05:14:12 PDT --- Update: Enabling "Repost Video On S3 Resume" in BIOS seems to help a lot. I've send my computer into sleepmode for a couple of times now and the second monitor has always been working fine after resuming.

I actually dunno what this BIOS option does, but it seems to be a solution.
