Everyone:
I asked this before under a different heading, and no one answered.
I get a large volume of e-mail, and very often I interact with a site
that brings up a lot of message boxes, "suggestion boxes" (for
auto-filling from a few keystroke clues), and bringing up apps after
they were minimized to the system tray or the task bar. Now why is it
that, after maybe two hours of operation, those popups come up and are
totally black? The only way to solve the problem, that I have found, is
to shut down. And even then, I can't even see what I'm doing, but have
to guess where the icons are for executing a controlled shutdown. (I can
always bring up a command-line login screen, log in as root, and then
shut down. But that doesn't seem to solve the problem for the next session.)
And when I log back on, everything's fine--until it starts happening
again, after several more window draws.
What could be causing this? Where do I even look for error logs and the
like?
I have no clue as to the cause, but doing a shutdown may be
unnecessarily heavy-handed.
Sounds like some kind of X or Gnome or related toolkit problem.
You could try CTRL-ALT-BKSP, which should kill X, effectively
logging you off, then log in again and see if things are again
working.
if that works there are probably other things to try killing to
see which one is causing the problem. One other idea would be to switch
to a text console, to "ps -u <your username>" to find out all the processes
you own then kill 'em all -- except for the text terminal you're using.
I haven't googled for "gnome troubleshooting", but you might find
something helpful if you did.
good luck!
Fred
I don't use Gnome. I use KDE. Do you suggest this is a KDE issue, and
not an F18 or screen display driver issue?
