Description of problem:
(I'm not sure which component caused this problem, of course, or even
what my actual window manager process is under gnome. I'll describe
as much as I can.)
My entire X desktop locked up a few minutes ago. Unfortunately, I
don't know what I did just before it locked up (I was moving back and
forth between multiple computers), but it was probably nothing more
than switching windows or virtual desktops.
Symptoms were as follows:
1. First, the pointer was invisible. I moved the mouse around, trying
to find it, but I could not.
2. Then, I tried to switch between windows with Alt-Tab, thinking that
an app might have blanked out the cursor. The currently-selected-
window box in the middle of the screen appeared as usual, and the
heavy rectangle around the currently selected window appeared, but
when I released Alt-Tab, the boxes did not go away and the window that
should have been selected (Emacs) did not rise to the top and redraw.
3. All further X input events after that point produced no visible result.
4. Ctrl-Alt-F1 switched to VT 1 successfully. Switching back showed
the same screen I'd seen before with one notable exception: the
gnome-panel I have at the top of my screen was not visible. In its
place was garbage data.
5. I switched back to VT 1 and tried kill -HUP <gnome-session pid>,
hoping it might do something reasonable with a SIGHUP like restart the
window manager. The X server restarted and returned to the login
screen. Logging in again resulted in the same empty desktop I got
when I first logged in after upgrading from Red Hat 9 to Fedora Core
2. Aside from that, everything seems to be working as usual.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. No clue. I don't recall doing anything I haven't done a thousand
Actual Results: Desktop locked up
Expected Results: Um. Yeah. I guess I would expect the desktop not
to lock up.
