The radeon driver and/or microcode still has bugs that lead to GPU
crashes. One or more of the xscreensaver modules can trigger a crash. Once
the GPU is dead, you may still be able to do something about it. For example,
I have sometimes been able to type in a "shutdown -r now" and have it work,
but only if either an xterm is currently the window in focus or I can move
the cursor to a place I remember has an xterm and then clicking on it to get
the focus to that xterm. Unfortunately, the ctl-backspace method doesn't help
because even if the X server quits, there is still no display of the console
because the GPU is halted/looping/whatever. A full reboot appears to be
necessary to reset and restart the GPU. It would indeed be good to have an
easy way to recover without rebooting, e.g., using the F11 or F12 key as a
way to run some command that could reinitialize the GPU.
