Public bug reported:
I run a setup of 2 radeon graphics cards, with 3 screens, in the
following layout from left to right counting from 0:
Card 0 Screen 1, Card 1 Screen 0, Card 0 Screen 0 rotated ccw
I have been running this setup for a year and it has worked fine. This
monday I updated some packages and did a reboot, and I usually reboot
just once a month cause I patch my running kernel with uptrack.
After the reboot I started noticing problems with the second card, Card
1 above. With a mean time between failures of about an hour, the second
card freezes the screen, I usually notice that the mouse pointer isn't
visible anymore when I move it across from one screen to the middle one.
For future reference, the window I have on the middle screen is a
fullscreen emacs window.
I have tried the following kernels: vmlinuz-3.13.0-77-generic,
vmlinuz-3.13.0-79-generic, vmlinuz-3.13.0-83-generic
All have the same problem. And nothing shows up in dmesg when the freeze
occurs, or in the Xorg.0.log, I made copies from before and after a
freeze.
If I move the mouse, that I can't see, onto the middle screen, make
emacs the active window (again I can't see this), scroll around a bit
with the arrow keys and take a screenshot, the screenshot shows the
correctly scrolled window, so the big X buffer is actually correctly
updated.
If I CTRL-ALT-L to lock the screens, they all go black, but when you
press enter only the screens on Card 0 shows the lock screen, the middle
one again shows frozen emacs.
CTRL-ALT-F1 shows two text terminals on the outermost screens, in the
middle, you've guessed it, frozen emacs.
If I go to the menu and select Switch user, surprise! Now the frozen
screen is gone and it is a gray login screen with the login menu
actually on the screen to the right.
Log back into my still running user, boooooooh, it again shows the same
frozen emacs.
Switch to a completely new user, screen in middle is correct and
working.
And lastly if I log out completely from my user and log in again the
screen is now unfrozen, but I have lots of work and it is really really
annoying to have to log out 8 times during a day at work.
I'm gonna try one more ancient kernel just to see if there have been
some changes to drm or the radeon driver, but I am pretty stumped on
this one. It all worked fine last week.
