GNOME Bugzilla – Bug 599116
Ctrl, Alt, Tab in sequence does not work on the login screen
Last modified: 2013-12-16 20:06:23 UTC
When StickyKeys is enabled on the login screen, pressing/releasing the following keys in order, taking care to not press more than one at the same time, should allow the user to switch to the bottom panel: Ctrl, Alt, Tab. It does not work on the login screen, but it does work in the normal user session. See also http://mail.gnome.org/archives/gdm-list/2009-October/msg00007.html
I can verify that this does not work in the GDM screen. However, in my testing, this also does not seem to work in the normal user session after I enable sticky keys.
we now use a normal user sesssion, slightly tweaked for the login screen.
