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

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).

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,
Andr?

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

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.

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).

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?

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.

Please attach your dmesg output from after the display does not come back.  Is
this a regression?  If so, can you bisect the kernel?
