[Bug 608833] Re: Gnome Panel hangs and renders touchpad and mouse unusable
Got it! What was messing up the panel and mouse clicks was my xmodmap button mapping on the mouse. I've been using this since 7.04, but it appears that things got a lot more sophisticated recently, and you shouldn't use xmodmap for button mapping unless you really do want to modify the settings of the virtual mouse device and get the effects I've been seeing. What you should do is use xinput, which allows you to modify the button map of a specific hardware mouse, and in a way which is a lot more flexible than xmodmap (e.g. two different physical buttons can be mapped to the same logical button, etc.). What triggered the panel problems was either extended use over several days, or use of VNC (vinagre). I guess that with no subscribers and having fixed my problem this bug is going to wither and die now. -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Further info - it looks like disabling tooltips on both firefox and the panel has resulted in fewer problems. The symptom which lead to me trying this was tiny tooltip coloured squares appearing near the panel, and really odd modal behaviour in Firefox in addition to the panel hanging. There have been previous bugs about tooltips in Firefox causing gnome-panel problems, so this might be a regression. It does not happen on my other machine which is almost identical apart from using the ATI proprietary driver. Now waiting another few days to see if things stabilise. -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 608833] Re: Gnome Panel hangs and renders touchpad and mouse unusable
I've been having too much problems with 10.04 on my computer. General slowness, keyboard not working on system startup sometimes (so I can't enter my user password, I only could use the mouse, but when executing the restart command from the shutdown menu, I got kernel panics, I'm sure they were kernel panics because the Alt-SysReq trick didn't work at all, and the boot screen was left frozen), Nautilus crashes, Gnome Panel crashes, and others. I really don't have the time or expertise right now to report bugs or gather the necessary technical info, so I downgraded to Karmic, on which I never had those kinds of trouble, and everything is working fine so far. If someone is affected by this bug, please try to get the info necessary to get it fixed.

[Bug 608833] Re: Gnome Panel hangs and renders touchpad and mouse unusable
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 Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 608833] Re: Gnome Panel hangs and renders touchpad and mouse unusable
@jpangamarca, The first attempt to get a backtrace did not work well. Gnome-panel has a very long list of dependencies though, and I only installed the debug symbols for gnome-panel itself. The effect that I got was that when the problem occurred the gnome debugger seemed to make the problem worse as none of my previously documented tricks for regaining control of the X session would work. I had to use the run application dialog to run killall gnome-panel. There was nothing in the backtrace after the initial startup messages (one for each dependency!) and it noting when I terminated it. The problem occurred when I was using an xpra session to an instance of thunderbird running under another user account on the same machine. There were some xsession messages, which are attached. ** Attachment added: xsession-errors-2 http://launchpadlibrarian.net/52636058/xsession-errors-2 -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Can anyone suggest a smaller set of debug packages to install than the whole list of gnome-panel dependencies which might help get a meaningful backtrace? -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 608833] Re: Gnome Panel hangs and renders touchpad and mouse unusable
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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 608833] Re: Gnome Panel hangs and renders touchpad and mouse unusable
@JimP, please try to get the backtrace. I'll still try too, but something happened: Just yesterday I disabled the nvidia propietary driver to see if that was causing the nautilus and gnome-panel hangs, but guess I'll never know because after disabling it, all I got on system startup was a black screen. There was no way to repair X server, so I had to reinstall Ubuntu, and I won't enable that driver for now. My computer is way faster without it. -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks for the report, could you attach your ~/.xsession-errors file to the report? would be also nice to get a backtrace of the gnome-panel hang, please have a look to https://wiki.ubuntu.com/DebuggingProgramCrash ; thanks in advance. ** Changed in: gnome-panel (Ubuntu) Importance: Undecided = Low ** Changed in: gnome-panel (Ubuntu) Status: New = Incomplete -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

.xsession-errors has been attached. But I've restarted my system already, is that file still useful? Or should I post it again when the crash ocurrs?
