Unable to start xfce4 session from lightdm

[maratbn]

So I have 'x11-misc/lightdm' version 1.24.0 installed, and configured to start automatically, which it does.  Before logging in, I click on the configuration icon in the upper right, and change 'Xsession' to 'Xfce Session', but when I do login, I still get the Xsession.

Here are my lightdm log files when I login if this is helpful:

Please advise...

it looks it trying to start consolekit, while it already started.

please, when you are not in X (and better after reboot) paste output of ls -l /etc/runlevels/*/*

Sure, the output is:

Also, here's the output of 'ps -ef | grep console':

root      2953     1  0 18:41 ?        00:00:00 /usr/sbin/console-kit-daemon --no-daemon
root      3143  3134  0 18:43 pts/0    00:00:00 grep --colour=auto console

So then what I did was I killed 'console-kit-daemon', and selected "Xfce Session" again, and this time it did log me into Xfce.  However, looking at the lightdm logs, it still complained about starting a ConsoleKit session:

So manually killing the 'console-kit-daemon' did let me log into Xfce.  But what is it that's triggering it to start?  It does not appear to be included in the 'boot' and 'default' runlevels.

[Oleg Vinichenko]

no consolekit in boot and default runlevels does not necessarily mean this service is not started by some other services. There are service dependencies capabilities in openrc which could make the service start other service even if it's not explicitly enabled. But i think xdm, which is in your default level could be a problematic one.
