I've found out that restarting gnome-panel also restores the desktop to a functional state. Also, the 'mouse movement' needed to unblank above is one that takes the mouse cursor over one of the panels, nothing else will do. So this is pointing at gnome-panel, rather than metacity. gnome-panel-2.17.91-6.fc7 It appears that, if I always use the mouse to switch from one desktop to another, and to switch from one window to another, I never trigger this problem. This problem is most common when I switch to a VT where a full-screen 1280x1024 firefox is running, but I have seen it happen in other cases as well. It looks like it's strongly related with the use of emacs-22.0.93-6.fc7. Whenever the focus is on Emacs, Alt-Tab or Ctrl-Alt-Arrow triggers the problem, as the pop-up to select the active application or workspace fails to pop up. Ctrl-Alt-number selects workspaces reliably (since there's no pop-up?). I couldn't find any keystroke to switch focus away from an Emacs window to some other window on the same virtual desktop :-( FWIW, a build of GNU emacs --without-gtk does not expose this problem. So it might be a bug in Emacs, not in gnome-panel, after all, but it's a bit scary that misbehaving applications can freeze the entire desktop like this. This appears to be the same as or related to bug 224611 and can be worked-around by disabling assitive technologies, if you don't need them. Mark this as a dupe? (In reply to comment #5) > This appears to be the same as or related to bug 224611 and can be worked-around > by disabling assitive technologies, if you don't need them. Mark this as a dupe? Very likely. Alexandre: please try disabling assitive technologies, log off, log back on and see if the problem goes away. If so, we'll close this as a duplicate of 224611. BTW, 224611 shows up on RHEL 5 and probably FC-6 also. The difference seems to be that FC-7 ships with assitive tech switched on by default. Chip |
