I've had this problem since 9.10. It only started affecting me badly enough to want to do something yesterday, and now I find there is a bug report for it. Here's my setup, which differs in a number of ways to jpangamarca's - specifically, I'm using the open source radeon driver and I'm not using compiz at all.
DistroRelease: Ubuntu 10.04 (also affected me in 9.10) Package: gnome-panel 1:2.30.2-0ubuntu0.2_i386 ProcVersionSignature: Ubuntu 2.6.32-23.37-generic 2.6.32.15+drm33.5 Uname: Linux 2.6.32-24-generic i686 NonfreeKernelModules: Architecture: i386 Date: Mon Jul 27 16:34:04 2010 InstallationMedia: Ubuntu 10.04 LTS "Lucid Lynx" - Release i386 (20100429) ProcEnviron: PATH=(custom, user) LANG=en_GB.utf8 SHELL=/bin/bash SourcePackage: gnome-panel I have a mouse button remapping using xmodmap, as my mouse needs buttons 1 and 3 remapped to 8 and 9 when it is used in presenter mode. I'm using the Human theme with a small number of customisations. The problem happens with Firefox, Nautilus and maybe one or two other apps open, but I have tried not using each of the other apps for a time, and it still happens in the absence of other apps. Firefox and nautilus are often open for long periods of time - like between kernel updates. Other things I have noticed which may or may not be relevant: Sometimes you can get out of the hang by switching to a virtual terminal then back to X. Closing nautilus sometimes causes the problem to go away. Often a click away from the panel causes the item on the panel which is above the mouse pointer to be activated - sometimes u clicking a different button un-freezes the panel when this happens. The panel is set to autohide, and one of the symptoms is it gets stuck in either hidden or non-hidden mode. Clicking on other applications buttons has no effect, although sometimes opening a panel menu and clicking elsewhere on the desktop brings it out of that mode. I have seen similar behaviour when the machine is running very low on memory. I do not get the behaviour on my other machine, which is rarely on for more than a few hours continuously, and which is almost identical other than having a more recent ATI graphics card, and uses fglrx. As I see this problem pretty regularly, I can probably provide a backtrace fairly soon if needed. -- 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 Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
