Update: I've not hit this bug after 5 days now, and I need to restart
to apply security updates.
To recap, the fix was to add the following to /etc/rc.local :
echo auto > /sys/class/drm/card0/device/power_profile

Radeon.dpm managed to crash the whole system (had to do a hard cutoff,

I've switched the power management back to "profile", but instead of
using the default profile I've switched to "auto". After 15 tries I've

I remembered that I had some kernel parameters set, so I turned off the
CLUTTER_VBLANK fix and experimented a bit. I used gnome-shell to
suspend, then resume and log in repeatedly until gnome-shell locked up.

Well, after 3 days and I don't know how many suspends / lock screens
later this bug hit me again. Let me see if I can get some more
information.

I cannot install a daily build on this machine, is there a live-usb
image with gnome-shell I can test?

I finally found some time to work on this, and I think I have it fixed.
Debugging gnome-shell when I hit this bug (note, I could also trigger
this bug by allowing the screen to lock, no suspend necessary) I noticed
the following backtrace kept happening:
Thread 1 (Thread 0x7f920ec68a40 (LWP 12089
Instead of doing that, I decided to do a quick sanity check.
I installed kernel 3.4-precise from the upstream kernel archives, which
I know worked fine when I was running 12.04 with gnome shell (even the
updated gnome-shell from the webupd8team ppa, I believe the version was
3.8?)
Sure enough, I'
Just tried 4.0.0 , and on first try I triggered this issue. I was,
however, able to kill gnome-setting-daemon and then gnome-shell from a
terminal. This then caused the lock screen to appear and I was able to
log in. I've had this happen sometimes in the past before, so I
consider this no change

Possibly related to bug 1283938 . I have disabled lock screen on suspend
to try and get around the bug but it obviously hasn't worked.
I see a completely black screen with a working mouse cursor. Used Ctrl-
Alt-F2 to login at a text terminal and tried to kill gnome-settings-
I can reliably trigger this bug on my machine in the 3.16 and 3.13
kernels. I've attached the kernel crash output for 3.16 (minus the dump
because of its size, I can provide a link if desired).
Adding wacom to /etc/modules prevents this bug for me.
