Appears to be a duplicate of bug 479826. I fixed it by removing:
~/.gconf/apps/panel/general/%gconf.xml ~/.gconf/apps/panel/toplevels/panel_1 I think it could be related to dual monitors. I have my laptop, and then my 24" Dell LCD that I plug into. On the Dell, when it's plugged in, I have a panel set to auto hide. When it's not plugged in, that panel doesn't show up on the laptop screen. This all happened randomly when I was not plugged into the monitor. It's a bit scary how it can completely destroy your entire system. I couldn't connect to wireless easily because the wireless applet was gone, it killed X and froze everything, used up tonnes of CPU and memory. When I removed gnome-panel it basically rendered everything (including Nautilus) useless. Quite a major bug I would say, depending on how often it happens. -- [Lucid] Gnome-panel applets disappear, freezes, locks up computer, 99% CPU usage https://bugs.launchpad.net/bugs/545521 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
