The standalone change-username script has to kill the xserver. Below is the section that determines what gets killed. I just added slim. Are there any other display managers that need to be added, and does slim show up as slim in ps? Hm... I guess another good question is whether or not something else might show up in ps that has the letters s-l-i-m in the name? That could be a problem.
- Code:
# Test if xinit or a display manager is running, and save the information
# for later use.
if ps -C xinit; then
dm_status="no"
elif
ps -C gdm; then
dm_status="yes"
dm="gdm"
elif
ps -C gdm3; then
dm_status="yes"
dm="gdm3"
elif
ps -C kdm; then
dm_status="yes"
dm="kdm"
elif
ps -C xdm; then
dm_status="yes"
dm="xdm"
elif
ps -C lightdm; then
dm_status="yes"
dm="lightdm"
elif
ps -C slim; then
dm_status="yes"
dm="slim"
fi

Depends if you want to support the Trinity (kde3 fork) DM, "tdm" .. It's used here.
Unfortunately using ps -C this only works for the "testing" (but due for release quite soon) version R14
The current 3.5.13-2 release can only be detected as "kdm" using ps -C because the actual process is /opt/trinity/bin/kdm (not tdm till R14)

could test
- Code:
xset -q
but that wouldn't provide a name
nor does
NAME
pidof -- find the process ID of a running program.
SYNOPSIS
pidof -s -x -o omitpid -o omitpid.. program program..
DESCRIPTION
Pidof finds the process id's (pids) of the named programs. It prints those id's on the standard output.
...so what you've already coded seems best

I don't remember where I found it, but this is in my notes. (gedit is just an example)
- Code:
ps ax | grep gedit NO!
ps -C gedit
pgrep gedit
ps -C gedit -opid= # show the pid for the given command
ps -p <pid> -ocmd= # show the command for the given pid
pidof gedit (obsolete)
- Code:
xset -q
Hm... That says DPMS is off, yet my xorg.conf has Option "DPMS" in it. Now I'm getting way off topic. Gonna look into this some more - my monitors don't go as black as I'd like when I leave the computer for a long time.

Does it run as "mdm" or does it run as "mdm-<something>"? Running 'apt-file find mdm' shows mdm-run, mdm-sync and mdm.screen in /usr/bin/.
I also came across mention of awesome window manager. Guess I need to add that, too, and I have the same question about it - what name does it use when running. Killing everything with 'adm' in its name is starting to get scary. I can imagine a process with 'admin' in the name getting killed by mistake. I might need to beef up the tests a bit or get some user interaction in there.

there is quite a few mdm entries, not sure which you are looking for. here is a screenshot

This change to the original test code correctly detects (here, in wheezy and sid) Trinity DM, both current "release" and "testing" versions:
- Code:
#!/bin/bash
# Test if xinit or a display manager is running, and save the information
# for later use.
if ps -C xinit ; then
dm_status="no"
elif
ps -C gdm ; then
dm_status="yes"
dm="gdm"
elif
ps -C gdm3 ; then
dm_status="yes"
dm="gdm3"
## changed: ##
elif
ps -C kdm ; then
dm_status="yes"
# Trinity DM (3.5.13 versions) actual PID shows as "kdm"
if /usr/sbin/sysv-rc-conf --list kdm-trinity|grep ":on" ; then
dm="kdm-trinity"
else
dm="kdm"
fi
## added: ###
elif
# Trinity DM (R14 "testing" versions)
ps -C tdm ; then
dm_status="yes"
dm="tdm-trinity"
###############################
elif
ps -C xdm ; then
dm_status="yes"
dm="xdm"
elif
ps -C lightdm ; then
dm_status="yes"
dm="lightdm"
elif
ps -C slim ; then
dm_status="yes"
dm="slim"
fi
echo "$dm is detected"
# shutdown detected DM
# service $dm stop

@raymerjacque: Could you post the ouput of this command for me, please? That way, I can see what processes are actually running when you're on the desktop.
- Code:
ps ax |grep mdm
Thanks.
@dzz: Thanks, that looks much better.

Of maybe like this, so that sysv-rc-conf isn't needed. Can you test, please?
- Code:
elif
ps -C kdm ; then
dm_status="yes"
if ps -C kdm-trinity; then
dm="kdm-trinity"
else
dm="kdm"
fi
elif
And just to make sure I understand correctly - there's no plain "tdm" in the ps output, just tdm-trinity?
