consolekit-daemon is running, lxpolkit is not but that never interfered with lxsession-logout, all rights in ~/ are fine.
lxpolkit is part of lxsession but in openbox you have to use it manually or put it in autostart if it is needed. lxsession-logout worked either way.
When it is run from terminal it does not produce any error, it just take too long and when it appears the shutdown/reboot options are not there. Only logoff cancel and lockscreen.
It shows in tasks as taking up memory but for 2' there is nothing.
Finally I got it to produce an error, not on terminal but a gui note, after I had run lxpolkit:
Error initializing authority: Error calling StartServiceByName for org.freedesktop.PolicyKit1: GDBus.Error:org.freedesktop.DBus.Error.TimedOut: Failed to activate service 'org.freedesktop.PolicyKit1': timed out (service_start_timeout=25000ms)
Also with trying lockscreen I got this:
which: no slimlock in (/usr/local/bin::/usr/bin::/bin::/sbin::/usr/share/man::/opt/::/usr/local/bin:/usr/bin:/bin:/sbin:/usr/share/man:/opt/:/usr/local/sbin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl)
Forget that 25s it takes more than 2 mins to pop out its screen
In all years on openbox/lxde I've never encountered this behavior. It is that stinking freedesktop crap crawling everywhere.
I don't have slimlock or any other screen locker, I never use that stuff.
