Public bug reported:
I wanted to try mir, I installed the unity-system-compositor package (no
ppa), and restarted my computer. After the reboot the process "unity-
system-compositor" wasn't running, it seems like a bug:
There is this in my lightdm log:
...
[+0.49s] DEBUG: Launching process 1482: /usr/sbin/unity-system-compositor.sleep
--from-dm-fd 10 --to-dm-fd 13 --vt 7
[+0.49s] DEBUG: Seat: Waiting for system compositor for 60s
[+0.49s] DEBUG: Acquired bus name org.freedesktop.DisplayManager
[+0.49s] DEBUG: Registering seat with bus path
/org/freedesktop/DisplayManager/Seat0
[+5.18s] DEBUG: Seat: Compositor closed communication channel
[+5.31s] DEBUG: Process 1482 exited with return value 1
...
And this in the USC log (this is the whole file):
ERROR:
/build/buildd/mir-0.0.10+13.10.20130827.1/src/server/graphics/gbm/real_kms_output.cpp(185):
