Created attachment 96427 [details] XOrg Log Description: I've got a Turks XT and the gnome power management timeout causes my screen to turn off but it often does not come back (meaning moving the mouse and/or typing on the keyboard have wake the screen but I see only black). Attempting to switch to a terminal from out of X by using ctrl-alt-fx does not seem to enable the display either but I am able to login (without seeing anything) and reboot the box. The screen is on and wakes from sleep but usually nothing is displayed. Sometimes there is a flickering line at the top of the screen. Relevant output from lspci: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Turks XT [Radeon HD 6670/7670] Additional info: xorg-server 1.15.0-5 xf86-video-ati 1:7.3.0-1 I've attached my Xorg.0.log Not sure if any extra info would be contained other logs (and not sure where to find them) but I would be happy to follow up if needed. Steps to reproduce: Start Computer Login to GDM Leave and let computer idle Return and try to wake computer Screen is now permanently black
Please attach your dmesg output from after the display does not come back. Is this a regression? If so, can you bisect the kernel?
I found nothing in the logs yesterday but then when I came into work today the monitor was flickering and essentially dead. I plugged in another monitor and everything works just fine. It was just the monitor dying! Thanks for taking a look Alex.
It seems it's doing the same thing with the new monitor... there is definitely something wrong. Is there another place I can look besides the dmesg output from the systemd journal?

Created attachment 96662 [details] System returning from lock-screen sleep Today when I woke the computer it had a black screen, switching to terminal showed the terminal shifted from off center (usually the login text appears at the top left of the screen).
Any thoughts Alex? I basically need to restart my computer almost every time the screen turns off. I have no problem providing any help I could give you guys in figuring this out.
Does manually turning off the display also cause problems? e.g. run: xset dpms force off xset dpms force on from a terminal Can you get remote access to the box (e.g., ssh)? If so can you try manually turning the displays on/off? E.g., DISPLAY=:0.0 xset dpms force off DISPLAY=:0.0 xset dpms force on or DISPLAY=:0.0 xrandr --output DVI-0 --off DISPLAY=:0.0 xrandr --output DVI-0 --auto
Hi, I think that I've the same problem. I've a "ATI Radeon XPRESS 200M 5975 (PCIE)" (ChipID = 0x5975) (from Xorg.0.log). Here already DISPLAY=:0.0 xset dpms force off brings the screen back. I'm running Kubuntu 14.04 32 bit. Cheers, André
I set the suspend time to two hours now but even after a much shorter time (lets say 10 minutes) the graphic is displayed and when I press any key the screen becomes black. xset q says that the monitor is still on. If I press more keys it takes a while (maybe minutes) til the sreen resumes. I think I had similar problem on another box (with Radeon HD 5570) with Debian Sid x86_64. But it seems not to happen any more for some days now (maybe the update to Linux 3.14).
I'm seeing new messages now when I look in dmesg: [drm:radeon_dp_link_train_cr] *ERROR* clock recovery tried 5 times [drm:radeon_dp_link_train_cr] *ERROR* clock recovery failed
