I won't know for sure until a few days has passed without this problem re-occurring, but I think I may have found out what was going on, on my machine at least. Looking at the apps/panel settings in gconf-editor I noticed that the entry which contained the settings for the workspace switcher had become corrupted. On another machine it appears as:
/apps/panel/applets/workspace_switcher_screen0 On the machine with the problem it appeared as: /apps/panel/applets/applet_6 There was also another key named applet_6 under /apps/panel/applets, but this was a name/value pair, not a key with subkeys. Applet_3 to applet_5 were all instances of Glipper, which has a bug that it sometimes fails to start when you log in, and asks if you want to remove it from the panel. What I have done is to clear out all my apps/panel settings back to defaults using gconftool. This crashed the panel session, and the machine had to be rebooted to get back to an X session which worked, but after the restart the new default panel seems to be fine, and the odd gconf settings are all gone. I've gone back to using the combination of apps which caused the worst problems, but I have left Glipper off the panel for now. I have also backed up my panel settings using gconftool. In case anyone reading this needs to know the gconftool commands I used, here they are: To reset the panel to defaults (WARNING: THIS WILL CLEAR THE PANEL OF ANY CHANGES YOU HAVE MADE TO IT): $ gconftool --recursive-unset /apps/panel To backup the panel settings: $ gconftool --dump /apps/panel > ~/gnome-panel.xml To restore the panel settings: $ gconftool --load ~/gnome-panel.xml -- Gnome Panel hangs and renders touchpad and mouse unusable https://bugs.launchpad.net/bugs/608833 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-panel in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
