Dear Adam, thanks for taking time to test. I tried again this morning and it crashed. Now, I am trying again to diagnose the problem, which does not always happen. Here is what I did:
1) Logged in as user 1 2) Selected 'Switch User', it opens a new gdm scrren on tty3 (tty2 was already opened by me manually) 3) Login as user2 4) Selected 'Switch User', it opens a new gdm screen on tty4 5) Go to tty3, using ctrl+alt+f3, and notice that the shell for user 2 has crashed. I took a snapshot of the systemd-journal at every step. Here is a diff of the snapshots between 4 and 5: < -- Logs begin at Wed, 2013-05-01 11:20:00 CEST, end at Wed, 2013-05-01 11:26:14 CEST. -- --- > -- Logs begin at Wed, 2013-05-01 11:20:00 CEST, end at Wed, 2013-05-01 > 11:27:00 CEST. -- 1721a1722,1792 > May 01 11:26:41 linux-3xop.site /etc/gdm/Xsession[1089]: > (gnome-settings-daemon:1204): keyboard-plugin-WARNING **: Couldn't find XKB > input source 'ch+de' > May 01 11:26:41 linux-3xop.site /etc/gdm/Xsession[1089]: > (gnome-settings-daemon:1204): keyboard-plugin-WARNING **: Couldn't find XKB > input source 'ch+de' > May 01 11:26:41 linux-3xop.site /etc/gdm/Xsession[1089]: > (gnome-settings-daemon:1204): keyboard-plugin-WARNING **: Couldn't find XKB > input source 'ch+de' > May 01 11:26:47 linux-3xop.site /etc/gdm/Xsession[1089]: > (gnome-settings-daemon:1204): color-plugin-WARNING **: failed to get devices: > The name org.freedesktop.ColorManager was not provided by any .service files > May 01 11:26:49 linux-3xop.site /etc/gdm/Xsession[1899]: > (gnome-settings-daemon:2007): keyboard-plugin-WARNING **: Couldn't find XKB > input source 'ch+de' > May 01 11:26:49 linux-3xop.site /etc/gdm/Xsession[1899]: > (gnome-settings-daemon:2007): keyboard-plugin-WARNING **: Couldn't find XKB > input source 'ch+de' > May 01 11:26:49 linux-3xop.site /etc/gdm/Xsession[1899]: > (gnome-settings-daemon:2007): keyboard-plugin-WARNING **: Couldn't find XKB > input source 'ch+de' > May 01 11:26:49 linux-3xop.site /etc/gdm/Xsession[1899]: > (gnome-settings-daemon:2007): color-plugin-WARNING **: failed to get devices: > The name org.freedesktop.ColorManager was not provided by any .service files > May 01 11:26:55 linux-3xop.site dbus-daemon[554]: dbus[554]: [system] > Rejected send message, 2 matched rules;

gnome shell has crashed. I think this is the moment where it has crashed: polkitd[625]: Unregistered Authentication Agent for unix-session:5 (system bus name :1.155, object path /org/freedesktop/PolicyKit1/AuthenticationAgent, locale en_US.UTF-8) (disconnected from bus) > May 01 11:26:58 linux-3xop.site gnome-session[1899]: WARNING: Application > 'gnome-shell.desktop' killed by signal 5 > May 01 11:26:58 linux-3xop.site gnome-session[1899]: WARNING: App > 'gnome-shell.desktop' respawning too quickly So, I think the problem might be related to polkitd. Actually, this problem has been reported on other distros too, for other versions of gnome. For example: https://bugs.launchpad.net/ubuntu/+source/policykit-1-gnome/+bug/970897 However, I have no idea how to fix the problem Valerio -- To unsubscribe, e-mail: [email protected] To contact the owner, e-mail: [email protected]
