Description Forgotten User OS1JNCFbCX 2005-10-10 15:58:54 UTC

Since today I have a very strange effect on a ThinkPad T42p running 10.1 alpha1.
The interesting thing with this problem is that it does now occur reproducable
although it did never occur before and I did neither install new software nor
did I change the setup of the machine in any way.

The problem is that whenever any KDE application produces sound output the X
server does no longer react to the keyboard. The mouse pointer can still be
moved but clicking to any place on the desktop does not have any effect. What I
still can to is switching to a text console and running any application there. I
can even restart the X server from there which again results in a running X
system until another sound is played. This even happens after the whole system
is rebooted.

There is no message in syslog when the problem occurs.

When I unload all sound drivers before logging into KDE everything runs stable
(but obviously the sound).

The sound chip in the machine is a "Intel Corporation 82801DB/DBL/DBM
(ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 01)".

Any idea where I could look for the source of this problem? Any stale socket
file or something like that?

Hmm, now works again without changing anything.

Still the question: Do you have any idea what could have caused this?

No certain idea.  The X driver problem?
