xrandr --verbose
Does the other monitor work properly if you turn it off and then re-enable it with xrandr (e.g., --off, followed by --auto)? Does doing a VT switch before suspend help? No / No. 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. Does the second monitor enable properly if you cold boot without it attached and then attach it after X has started? 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. Created attachment 37316 [details]

(In reply to comment #8) > 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. 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. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.

Created attachment 37311 [details] 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.
