Would you expect a crash in this situation?
I brought my laptop to work for some reason and left it running on
battery. I also had Banshee running, albeith on low volume. I had to
leave my place for a bit and when I got back the laptop had gone into
hiberantion.
Then when getting home, I booted it and found Banshee playing, and the
screen all scrambled impossibly to see anything (large sheets of
colourful squares).
The only way to get out of this mess was to open a console and enter
reboot as root. Is it some bad handling in Banshee/KDE/Fedora or
something?
I cautiously offer that it might have been the screen saver kicking in, but
in general video doesn't get properly initialized after hibernate. On many
machines it doesn't need to have the video hardware reset, so it doesn't
matter, and I'm told that using a vendor driver may solve the problem.
That's information, not suggestion, treat with care.
One thing which may work, and has worked for me, is to switch to a text mode
console, and instead of logging in or anything, switch back to the graphic
screen. I think this resets the video back to a sane graphic mode, but
that's a guess. Another thing which has worked for me on some laptops is to
switch to a text mode before doing the hibernate. That implies you know
you're going to do it. Sometimes killing and restarting X will fix the
issue.
May some of this be useful, these are tricks which have worked for me or
friends, hardware and drivers differ enough for me to help any more.
Ah ...
This all sounds familiar. Some of it I've resorted to before.
I'm so rusty using desktop Linux =)
I used desktop Linux from the early days of the "MCC four floppy distribution"
but didn't get rid of my last Windows machine until about 1998. I keep a VM just
to test web pages against IE, but other than that 15 years without MSFT.
