I find in http://askubuntu.com/questions/4408/...ubuntu-freezes
For a fully locked up system (mouse unresponsive) during a Firefox session, I found the following directions:
"If it locks up completely, you can REISUB it, which is a safer alternative to just cold rebooting the computer.
REISUB by:
While holding Alt and the SysReq (Print Screen) keys, type REISUB."
The problem I find with this is that pressing Alt and the SysReq (Print Screen) initiates a screen capture.
Well actually a bunch due to KB repeat feature.
What am I not understanding here?
This is pretty important to me as I just went through a lengthy adventure with downloading an Ubuntu iso, booting livedisk, open term window, run fsck, correct a lengthy set of problems, and very luckily successfully re-boot.
All because Firefox froze the system and I had to hard reset the system.
I've had to do this before and didn't have a problem but once was more than enough thank you very much!
