Title:
unity lock screen provides no way to force-logout a user
Status in Unity:
Triaged
Status in unity package in Ubuntu:
Confirmed
Bug description:
Let me start by saying that I realize that unity's screen locker is
not the same thing as gnome-screensaver. That having been said, there
are major regressions in functionality with the advent of Trusty.
Virtually every site that uses Linux in any sort of public computing
areas makes use (or used to, at least) of gnome-screensaver's "logout-
delay" and "logout-enabled" functionality, which would, after the
screen had been locked for a pre-determined amount of time, present a
"Log Out" button that would end the user's session, optionally running
a custom command to do so. This is vital, lest people walk away from
their workstations, rendering them unusable by others until they are
rebooted.
unity's lock screen mode provides no way to do this. Right up until
the final beta, it was possible to swap out unity's lockscreen mode
for gnome-screensaver, but that was removed as well. I wouldn't mind
if it was possible to configure the alternate use of a screensaver,
but Unity goes out of its way to ensure you can't do this. If there's
some magic way to do this, by adding an applet to the panel when in
lockscreen mode, or by invoking some D-Bus black magic, I'd be happy
to hear about it.
But really, removing this level of functionality while simultaneously
preventing any workarounds, is a real problem.
Steps to reproduce:
1) Log in to a unity session.
2) Lock the screen.
3) Observe that org.gnome.desktop.screensaver gsettings keys are not honored.
4) Examine the com.canonical.unity* schemas and observe there is no way to enable this behavior.
