I can replicate this everytime..

Comment 1 Lubos Lunak 2005-04-25 10:48:08 UTC

It works just fine here. Is the problem specific to some application or can you reproduce it with any of them? Can you reproduce the problem with a fresh KDE account? Can you attach to the frozen kwin and provide the backtrace?

Comment 2 David Hubner 2005-04-25 18:14:36 UTC

It seems to be linked to this problem.. http://bugs.kde.org/show_bug.cgi?id=96602

Any window that has problem with size when shaded. The application was X-Chat. I shall attach and backtrace when i get home...

Comment 3 Lubos Lunak 2005-06-06 16:46:47 UTC

Waiting for the requested information.

Comment 4 David Hubner 2005-06-07 21:21:09 UTC

xsessions log

Comment 5 David Hubner 2005-06-07 21:23:01 UTC

Sorry forgot about this. 

It does not crash KDE but freezes X. It only happens when Xchat is set to shaded in the session. I have attached the Xsessions-errors log.

Need more info?

Comment 6 David Hubner 2005-06-07 21:51:02 UTC

I was wrong it does not look like kwin.. i have attached to it and it does not freeze on its own. Looks like ksmserver.

Comment 7 Lubos Lunak 2005-06-08 15:03:51 UTC

That log file doesn't seem to contain any useful information. Backtrace from the frozen application would be useful.

When i do a PS -A.. kde has started two Xchat instances and one is <defunct>

Comment 9 Lubos Lunak 2005-06-14 19:56:33 UTC

Can you reproducibly get the kwin backtrace with "KNotifyClient::startDaemon ()"? If yes, the problem might be with KNotify, or perhaps your sound system. Do you use arts (and start the soundserver)? Can you see knotify in the process list? Can you provide a backtrace from knotify?

Comment 10 David Hubner 2005-06-15 19:17:11 UTC

Yep.. everytime i reproduce it i get KNotifyClient::startDaemon ()

I use arts, i tried to turn off the soundsystem but i could still reproduce the bug. There is no knotify process running.

Comment 11 Maciej Dems 2005-10-26 21:32:12 UTC

I confirm this bug. I have made some test and it seems that problem is indeed with sound system. When you restore any window maximized/shaded etc. and the maximize/shade action produces any sound the KDE startup hangs on "Restoring session". It is enough to turn of the sound to have good behavior.
