Description Ancoron 2014-05-27 08:40:40 UTC 
Hardware:
- GPU: Sapphire Ultimate R7 250 (1002:683f, 1x DVI, 1x HDMI, 1x DisplayPort, passive)
- Monitor: Dell 3007-WFP HC (30", 2560x1600 @ 60)

Software:
- Ubuntu 14.04
- Kernel 3.13.0-27-generic
- linux-firmware package version 1.127.2


What happened:

After monitor wakeup, I just got back the picture of the desktop (not the usual locker screen though) but wasn't able to interact with it (no mouse pointer visible, no screen updates). I then switched to a virtual terminal and back again, but that didn't help either. I switched one more time and then got this:

Comment 4 Marek Olšák 2014-05-27 10:17:55 UTC 
Ancoron> Why did you change the bug product/component? This has nothing to do with the X driver.
Comment 5 Christian König 2014-05-27 10:53:38 UTC 
Indeed, changing it back.
Comment 6 Ancoron 2014-05-27 15:30:54 UTC 
Ah, now I see. Previously, the select boxes showed me component "DRM/Intel", that's why I changed it again.

Sorry.

I should probably note that I'm using the packages from the xorg-edgers PPA for Ubuntu.
