I have a reproducable issue on with an Intel G35 chipset using the Intel GMA 
X3500 running Debian lenny with the latest updates of today:

rd at blackbox:~$ dpkg -s xserver-xorg-video-intel|grep Version
Version: 2:2.3.2-2+lenny2
rd at blackbox:~$ dpkg -s kdm|grep Version
Version: 4:3.5.9.dfsg.1-5
rd at blackbox:~$ 

Whenever I end a session and kdm reappears (which happens as far as I 
understand without restarting X), the mouse freezes and is placed in the 
middle of the screen. The keyboard ist still working within kdm and I can 
switch to virtual consoles. Crtl-Alt-Backspace restarts the X-Server and this 
fixes then the mouse issue.

I checked Xorg.0.log on a virtual console, when the mouse hang. It contains 
these lines towards the end:

(WW) Configured Mouse: Grab failed (Bad address)
(WW) Configured Mouse: Release failed (Bad address)

For reference, the full Xorg.0.log and xorg.conf are at


Can anybody with confirm the problem? If yes, do yo have the same intel Xorg 
driver and kdm?

Can anybody advice if and if yes, against which package I should open a bug 
report? What information should be included?
