I'm running LTSP on edubuntu 8.04

Seems that when a thin client runs things like tuxpaint or gcompris or tuxtype the apps don't want to close correctly. Even firefox in some cases.

Is this a common problem? I have a large server, but I'm loading it up with processes.

I didn't have this problem last year with 7.04

Could you provide more details ? Any specific errors ?

This was common with 7.10, and a program called watchdog was written to
kill off the running processes.* Perhaps this is what you need?

It looks like watchdog or xterminator will help for the cases when apps
are still there on after logging out.

But right now I can't even close some windows while still logged in. On
a fully patched 8.04, if I can't even seem to close SDL apps like
tuxpaint or gcompris.
There is nothing being logged that I can see.

I recall an issue like this being reported before. One workaround was to
disable sound. It seemed like the problem related somehow to releasing
pulseaudio.

Could you try starting it from the command line and see does the problem
repeat? Then, set
export ESPEAKER=
export PULSE_SERVER=

and see does the issue go away. If it doesn't, maybe disable sound on a
thin client (in lts.conf) and try again. Obviously you want sound, but
this will hopefully help track down cause of the issue.

Looks like I can close the apps when clearing those env variables.
This worked for both wesnoth and tuxpaint.

Any chance going against an external ldap server for
authentication/authorization has anything to do with this?
(just in case sound requires certain groups)

Do you have some more info on this? The only watchdog app i can find is
for restarting the box.

Okay. We should probably get a bug reported in launchpad. As I recall,
last time this was brought up, we concluded that it was against apps which
used libsdl (tuxpaint, tuxmath, gcompris,...). I'm not certain what
package to file against in ubuntu. You could file against tuxpaint or
gcompris and see what the package maintainer makes of it.

Not that I'm aware. However, if you find this is an issue, please let us
know.
