I was getting a similar problem: (gnome-panel:2160): GLib-GObject-WARNING **: /build/buildd/glib2.0-2.30.0/./gobject/gsignal.c:2295: signal `size_request' is invalid for instance `0xcddac0'
I tried removing gnome-panels, and gnome-shell, however when you install gnome-shell you get gnome-panel. I thought it was graphics driver but it wasn't. If you log in as guest, gnome-shell works. (I was using Gnome without effects) Gnome shell default settings work. Therefore, it has to do with the settings. Also, I remembered I was configuring the gnome panels when the gnome shell started to crash. This is what fixed it for me: Go into terminal Code: cd ~/.config/dconf mv user use Log out or reboot. (I rebooted, lightDM problems) By renaming the user settings you make a backup at the same time. This just resets the gnome-shell settings and this worked for me. It took me a while to figure out where Gnome 3 settings were kept. I hope that helps. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-panel in Ubuntu. https://bugs.launchpad.net/bugs/879164 Title: gnome-panel crashes when trying to move panel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-panel/+bug/879164/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
