[blfs-support] LXDE: consolekit with lightdm (BLFS 8.2)

[Ben Bellemans via blfs-support]

I installed LXDE (BLFS 8.2).
I already had lightdm installed.

The BLFS book explains how to launch LXDE with xinit, by using "ck-launch-session startlxde".

When I start LXDE with lightdm, the shutdown en reboot options give errors.
"ck-launch-session" is used with xinit to prevent these problems.

But how can I use "ck-launch-session" with lightdm?

When I change /usr/share/xsessions/LXDE.desktop
so the Exec line reads:
Exec=ck-launch-session /usr/bin/startlxde
then the reboot and shutdown options simply disappear.

So, how to use consolekit with lightdm?
