Bug Description

Binary package hint: ldm

I log in into Gnome via LTSP client, no problem. I can execute applications perfectly. I have been always able to log out then, and session ended with no problem. But since I updated Edubuntu 7.10 with the latest patches, I couldn't do it anymore.
When I press "log out", nothing appears. Then, I'm not able to open any application other than Firefox, as far as I know. No error message is printed out. I have to manually switch off computer. It doesn't work, no matter which user is selected.
Then, if I switch on computer again, I'm able to log in again using LTSP, but the same error appears when trying to exit.
Ctrl+Alt+Backspace works stopping session, but then GDM is not starting again, so that's the reason why I posted bug here.
Thanks!!

can you check if gdm is running on the server, and if gnome-power-manager is running in the users session ?
the gnome logout dialog queries gnome-power-manager first for suspend hibernate capabilities and also uses gdm-signal. if neither answers that can cause the logout dialog to not appear.

hmm, actually reading over what i wrote above seems a bit confusing so let me rephrase that:

ltsp itself doesnt use gdm anywhere on the thin clients, logging in is done via ldm which runs on the client.

gnome which runs in the session ldm has spawned *on the server* has some functions that talk to the local gdm running on the server.
gdm itself has nothing to do with ltsp ... but with gnome and its session handling in some areas.

Ok! I will check what you told me before, and let you know if I discover
something.

Thanks!!

I have checked it and everything is started (gdm and gnome-power-manager),
but it seems that when I reload gdm with:
/etc/init.d/gdm restart
as root, on the server, then the log out dialog appears (with three options:
log out, change user and switch off). Anyways, it doesn't do anything, just
stops when I press the button.
I have tried with different users, the best thing I get is the dialog
appearing, but no luck at shutting computer down.
Something has changed in the last updates, I think, that has made it stop
working.
Thanks!!

I got this solved. The problem was I had gdm installed and up on the server.
I removed gdm from the server, and it worked again perfectly. Can this be
possible?? Would it be possible to mask gdm package and block it from
installing on Edubuntu?? Because it messes up everything. BTW, would it be
possible to put an advice on this, for example, on installation?

I don't know how it could get installed, it's even possible I installed it
unadvertedly.
Thanks!!

no, no, it is right to be installed and run by defaut on the server, that behavior isnt right though (and doesnt show up here)
if gdm and the power manager are installed and runing, do you see any errors in .xsession-errors of the user if you try to log out ?

I have to take a look tomorrow, then. BTW, now, it's working, so I'm going
to try it another way (maybe in a VirtualBox) if I have to misconfigure
something.
I'll take a look at the error log, to see if there's something wrong. Ok, I
can test it a bit further, but I'm afraid it will stop working again, since
it's for working.
One thing: is it normal that when you log in, when the gnome panel appears,
it shows a green-man logo, and then shows the other one as the Log-out
icon?? (the door with the arrow). It seems like "something" is getting on
top of it, or that the Theme changes automatically, since I have realized
that some icons change 2 seconds after logging in, just after they get
loaded for the first time. Maybe it has something to do with the other
thing.
Thanks!!!
