[Bug 815996] Re: Desktop occasionally freezes/locks up when switching workspaces

 

[GeForce 9300 / nForce 730i] (rev b1) running gnome-session-flashback

In my case, ONLY the gnome-panel running the desktop switcher applet
seems to completely block.  I can unreliably bring it back by playing
with the top gnome-panel.   I can reliably bring it back by "killall
gnome-panel".

While affected, i can move my mouse to within a few pixels of the top of
the screen and it will activate the on_hover of the application button
directly below it on the bottom panel.  E.X.  I run gnome terminal, its
application button appears on the bottom panel, i switch desktops
(creating the problem). and i can then make it active by clicking the
TOP of the screen directly above the button.

Regardless, the workplace switcher has NEVER reflected the windows in
the other desktops.

I moved to Metacity just to be able to work.

Will provide more info when time allows.

Bug description:
  I'm assuming the issue is related to Compiz, but I'm not 100% sure.
  When I'm switching workspaces, it occasionally locks up (becoming more
  frequent). Most of the time, I'm going from the current one down
  (Ctrl+Alt+Down Arrow), and it freezes mid slide. Typically, I'm able
  to correct things by backing out to a terminal then returning
  (Ctrl+Alt+F1, pause, Alt+F7), but sometimes when I return the dual
  screen setup acts as one large screen (windows are stretched to the
  full width of both screens) and many of the windows collect on the
  first workspace.

  
  Ubuntu 11.04 (Classic)
  All packages up-to-date.

  If there are any logs/etc that would be helpful, let me know.
