DCOP server doesn't terminate, causing shutdown block

[SheeEttin]

Everyone knows about that problem where you try to shut down, but you get stuck at a black screen with the cursor, right?

Well, I've tracked it down to a process that, when terminated, allows the shutdown to happen. The process is "dcopserver_shut" (or similar).

Anyone know if this is caused by the DCOP server itself, as I think it is? How about a solution? Should I just report it to someone involved with DCOP, file a bug report, or what?

Just an idea for a little hack, er, work around ...:

USER # mkdir ~/.kde/shutdown
USER # touch ~/.kde/shutdown/terminator
USER # chmod +x ~/.kde/shutdown/terminator
USER # echo '#!/bin/bash' >> ~/.kde/shutdown/terminator
USER # echo 'killall dcopserver' >> ~/.kde/shutdown/terminator

(As, from my experience, bugs are long-living :P)

So putting a script in ~/.kde/shutdown will cause that script to be executed on shutdown? Interesting... i wonder what else I could do with it.

Worth a try, at least (- further reading).

Believe me: you don't want to know

Re: DCOP server doesn't terminate, causing shutdown block

Hmm... doesn't work.
Apparently, it doesn't get executed at the right time. There's no dcopserver_shut process at the time of execution for it to kill. Could I make it wait a few seconds before attempting the kill? (Also, exactly when does the script get executed?)

By the way, the process seems to be a little tricky to kill (by usual standards, anyway). It isn't killed by killall, nor can you get its PID through pidof for kill. I eventually had to resort to "kill `ps -e | grep dcopserver_shut | cut -c 1-5`", rather complicated for killing one process.

Maybe because you're not trying what I've asked you for (?).

While I've suggested to kill the dcop server as a whole, you are trying to kill it's shutdown process ...

Re: DCOP server doesn't terminate, causing shutdown block

Well, that process, when killed, will allow the shutdown to continue.
But if you think that killing the DCOP server outright isn't a bad idea, I'll try that.

Re: DCOP server doesn't terminate, causing shutdown block

Well, that didn't work. Here's what I tried most recently:

#! /bin/sh
killall dcopserver
kill 'ps -e | grep dcopserver_shut | cut -c 1-5'

The dcopserver_shut process apparently doesn't appear until after the script is executed. (Whether it actually appears after the script, or the script merely executes too quickly is something to give thought to.)

So, is it possible to insert a delay into a script? If not, where could I put a script that would execute after the process appears but before it hangs, waiting for it?
