I have gnome-screensaver package installed for using Ctrl+Alt+L to lock the screen. Though locking the screen works fine, it takes a whole lot of time to unlock after entering my password at the prompt. The lock screen just freezes during the time (mouse is active).

Here are the log messages from $HOME/.cache/gdm/session.log

  1. When screen is locked:

    (gnome-shell:2850): GLib-GIO-WARNING **: Dropping signal ActiveSessionChanged of type (s) since the type from the expected interface is (o) 
    (above message repeated 5 times)
    
      JS ERROR: !!!   Exception was: TypeError: arguments[0] is null
      JS ERROR: !!!     message = '"arguments[0] is null"'
      JS ERROR: !!!     fileName = '"/usr/share/gnome-shell/js/ui/components/autorunManager.js"'
      JS ERROR: !!!     lineNumber = '133'
      JS ERROR: !!!     stack = '"(null,[object _private_Gio_IOErrorEnum])@/usr/share/gnome-shell/js/ui/components/autorunManager.js:133
      ([object _private_Gio_DBusProxy],[object _private_Gio_SimpleAsyncResult])@/usr/share/gjs-1.0/overrides/Gio.js:86"'
    
  2. When screen is unlocked:

    (gnome-shell:2850): GLib-GIO-WARNING **: Dropping signal ActiveSessionChanged of type (s) since the type from the expected interface is (o)
    (above message repeated 4 times)
    
    JS LOG: loading default theme (Adwaita)
    
    (gnome-shell:2850): GLib-GIO-WARNING **: Dropping signal ActiveSessionChanged of type (s) since the type from the expected interface is (o)
    (above message repeated 13 times)
    
    JS ERROR: !!!   Exception was: TypeError: arguments[0] is null
    JS ERROR: !!!     message = '"arguments[0] is null"'
    JS ERROR: !!!     fileName = '"/usr/share/gnome-shell/js/ui/components/autorunManager.js"'
    JS ERROR: !!!     lineNumber = '133'
    JS ERROR: !!!     stack = '"(null,[object _private_Gio_IOErrorEnum])@/usr/share/gnome-shell/js/ui/components/autorunManager.js:133
    ([object _private_Gio_DBusProxy],[object _private_Gio_SimpleAsyncResult])@/usr/share/gjs-1.0/overrides/Gio.js:86"' 
    (above block repeated 4 times)
    

Are these related to the long delay/freeze in unlocking the screen? or is it caused by some other software etc.

Glad to provide any extra information in this regard. Thanks.

Which display manager are you using. To know just run this command: sudo dpkg-reconfigure lightdm. On the list, the selected display manager will be your default. Reply.. –  Saur.K Sep 2 '13 at 9:48
    
Did you find any solution for this? –  heldt Sep 16 '13 at 7:53
    
^^ Nope. Not yet. @Saurav I am using gdm (comes by default on Ubuntu-GNOME) –  Siva Sep 18 '13 at 5:43
    
This looks like a bug. You should hit the bugtrackers (launchpad, gnome project) and, if you don't find any matching your description, report your own. –  David Foerster Sep 26 '13 at 11:03
    
Even I would like to know the answer. Happens to me on initial login. Could this be related to this bug –  465544 Oct 2 '13 at 15:53

@DavidFoerster: Yes it is a bug.

See here: Launchpad Bug #515155. You may also find a workaround there.

Install the Tweak Tool if not already installed and the Gnome Shell extensions. The extensions are enabled in the Tweak Tool / Advanced Settings. The alternative status menu extension displays the shutdown menu. You can adjust it there.
