<div>Hi Anders,<br>
I still think what you are looking for is SLiM<br>
<a href="https://en.wikipedia.org/wiki/SLiM" target="_blank">https://en.wikipedia.org/wiki/SLiM</a><br>
Please check this out. You can use SLiM instead of LightDM.<br>
There were no logout, or shutdown buttons present the last time I
used it in Debian Wheezy<br>
And it provides a lighter login.<br>
Of course, you could remove LightDM and setup your computer to run
startx (or whatever specific startup script Lubuntu uses... I
can't remember off the top of my head) instead :)<div><div class="h5"><br>

<div>The problem with going to the "real server guys" is that
terminal servers are sort of halfway between the
server/desktop divide, so some things fall on the desktop
side, and some on the server side. This specific issue is how
to get lxsession-logout to not show the shutdown/reboot
buttons, which I would deem to belong on the desktop side of
things. I may need to try the LXDE guys directly if nobody is
able to help here. I just thought I would try the distro
specific mailing list before going to the program specific one

Hi Anders,<br>

You can also ask in the Server Platforms Forum at<br>
