Public bug reported:
I am using LTSP fat clients, created with:
$ sudo ltsp-build-image --arch amd64 --fat-client-desktop ubuntu-desktop
LTSP server has sssd authentication utilizing pam and ldap. Users can
log in without issue and the home folder is available. Everything works
as expected except for screen locking.
When locking the screen, the displays first go blank and the monitor
goes to sleep.
Then if i move the mouse or press a keystroke, They go black but the
mouse is visible.
Once I move the mouse or strike a key the second time, everything comes
back up without password prompt. However, password prompt is enabled in
"Brightness & Lock"
The client hardware is an Intel NUC D34010WYK
Also maybe related, there seems to be no system tray. No clock or
username/logout buttons. I am using Ctrl + Alt + L to lock the screen.
(See attached screenshot)
This is a security vulnerability and I can not make the new 14.04 image
available as fat clients, since they users cannot lock their
workstation.
** Affects: unity (Ubuntu)
