Bugzilla Bug 99436

Using KDM login manager, /etc/init.d/xdm stop gives this message:
 * Stopping KDM ...
 * Error stopping KDM.

Subsequent attempts at /etc/init.d/xdm stop give this detailed and useful
error message:
 * Stopping  ...
 * Error stopping .

Nothing else appears in any logs, and I've been unable to figure out just
what it's puking on or why.  If anyone can tell me how to induce it to produce
more useful messages I will do so.

Reproducible: Always
Steps to Reproduce:
1. /etc/init.d/xdm stop


Actual Results:  
The xdm init script failed to stop the X service.

Expected Results:  
It should have stopped the X service.

fast check:

does kdm/xdm/gdm run (check with `ps ax`)

If not, zap it:

/etc/init.d/xdm zap


and start it again. (and yes, a lot of init scripts fails to detect some types
of errors during service start and needs to be fixed)

Please file bug reports, nothing else helps! :)

I'm unable to reproduce this with gdm or kdm.

Tyler?

Does it still happen for you?

Yes, it still happens, and yes, kdm is still running.  I don't need ps to
diagnose this when I can still ctrl-alt-f7 and login via the window manager.

When did this start?

Quick check:
1) Make sure etc-update has been done.
2) Run emerge -uavDN world
3) Run revdep-rebuild from the 'gentoolkit' package.

> When did this start?
I can't tell you.  I very seldom need to shut down XDM.

> 1) Make sure etc-update has been done.
Done.  No change.

> 2) Run emerge -uavDN world
I'm not going to rebuild my system world for a "quick check", especially when
I'd need to make heavy modifications to my portage.mask to deal with all the
annoying circularly-blocking packages the portage tree's aquired lately.  Even
if that solves it, I'd rather know WHY it was breaking.

See above.

2 is actually the proper updating method.  Rebuilding your system would be
`emerge -e world`.  That checks for updates and new USE flags for all packages,
world and deps.  Not doing that can break stuff.  This should only take a long
time if your deps are out of date.

3 does a further check to see if any depedency updates have broken other packages.

I can confirm that with kdm. I had a look at the init script and executed 
"start-stop-daemon --stop --exe --exe /usr/kde/3.4/bin/kdm" (which should be the 
main command in the "stop" function of the script) and that stopped kdm.

Then I removed the "--quiet" and the ">& > /dev/null" in the invocation of the 
"start-stop-daemon" in the script and still got no error message (although xdm 
didn't stop).

Maybe a bug in the rc-script? But why does "start-stop-daemon" doesn't show any 
error even if stopping kdm fails??

/etc/init.d/xdm from the baselayout 1.12 series also fails to stop gdm. Running
`/etc/init.d/xdm stop` says "Stopping gdm... OK", but a ps shows that there are
still two gdm processes and a gdmgreeter running.

I still haven't seen this happen on any of the up-to-date systems I've worked
on.  In any case, X should provide the xdm script, not baselayout.  What X
version do you have installed?

Well, the xdm script might be OK, I don't know, but baselayout-1.11.13-r1
works.

I'm using xorg-x11-6.8.2-r2.

I've actually seen similar on my system. Perhaps one of the baselayout guys
could clue us in why xdm fails to stop with newer baselayout versions.

Nevermind, saw the other bug.
