By default, Bugzilla does not search the list of RESOLVED bugs.
You can force it to do so by putting the upper-case word ALL in front of your search query, e.g.: ALL tdelibs
We recommend searching for bugs this way, as you may discover that your bug has already been resolved and fixed in a later release.

kdm waits for the end of kdm_greet.
krootimage and kwin remain like a zombies.
Reboot/shutdown from a running session is ok.
On the test machine with Precise it works fine.

Does [X-:*-Core] TerminateServer=true help?

Unfortunately, no.
It hang up the same way.

Today I witnessed identical conduct kdm_greet from KDE4.8.4 (Debian Wheezy)!

It is interesting that on Squeeze with kdm-trinity helped me to update libx11 to 1.3.6 - with this version I would never notice the problem. However Wheezy contains libx11 1.4.5. It's weird.

Slavek,
tdm seems to work fine. Do you think we can close the bug? Or are you still experiencing problems?
Many changes went into kdesktop and kdesktop_lock since the time of the report.

It seems that the problem is no longer up to date - it concerns obsolete distributions and does not occur in the current ones.
