Description Kamil Páral 2014-12-12 14:14:18 UTC 
I was working in Firefox and a notification popped up in my GNOME, when the display froze and the monitor turned off after a few seconds with "no signal" message. I waited about i minute, the screen did not come up again. Trying to switch to VT2 did not help. I had to use sysrq to do an emergency sync and reboot (that worked, kernel was not locked up completely). I don't know how to reproduce this, happened randomly.

Comment 1 Kamil Páral 2014-12-13 16:52:10 UTC 
This happened before I upgraded to the latest mesa-dri-drivers-10.3.5-1.20141207.fc21. It's possible it's fixed now. If you can't easily extract information about what's wrong, let's close it and I'll reopen if it happens again.
Comment 2 Michel Dänzer 2014-12-16 08:56:03 UTC 
Indeed, there was a fix in Mesa 10.3.4 which helped for issues like this for some people.
