system halt and reboot does not work when lightdm is opened several times

[Julien Aubin]

Bug tested against the KDE flavour of lightdm, with lightdm-kde-greeter. Do not know if it occurs with standard lightdm.

Steps to reproduce :
DO : open your first session using lightdm.
DO : now, while the first session is opened, open a second user session, again using lightdm (for example with the switch user command from KDE menu).
DO : close the second user session using the "disconnect" command from KDE menu. Note that lightdm is not killed from the second X started while it should, just as KDM did.
DO : now, from the first session, shutdown the computer.
EXPECT : the computer should be shut down.
ACTUAL : actually lightdm hangs after the session is closed, and user is forced to shutdown manually using the command line from a terminal.

The same problem occurs if the user restarted lightdm using service lightdm restart command.

What/where's the disconnect command from the KDE menu?

[Julien Aubin (gojulgarbmail)]

K Menu > Quit > Disconnect.

Closing assumed fixed.
