High, i habe here onto 2 laptop crashes with kdm. 1. installed is xdm and pam_mount 2. in /etc/pam.d/xdm where 2 lines addedt: auth required pam_mount.so use_first_pass debug session required pam_mount.so debug 3. reboot, graphical login, login, kde are working fine. 4. but after the logout (only session) dosen't restart the login screen, but the console screen. One messge in /var/log/messages for this is: Nov 16 13:01:02 efi kdm[1020]: Unknown session exit code 0 (sig 11) from manager process In /etc/init.d/xdm i habe added after the $DISPLAYMANAGER a -debug 15. So we can read in /var/log/messages a little bit more: Nov 16 13:33:12 efi kdm: :0[14494]: ping X server Nov 16 13:33:12 efi kdm: :0[14494]: X server alive Nov 16 13:33:12 efi kdm: :0[14494]: source reset program /etc/X11/xdm/Xreset Nov 16 13:33:12 efi kdm: :0[14494]: source /etc/X11/xdm/Xreset Nov 16 13:33:12 efi kdm: :0[14744]: execute: /etc/X11/xdm/Xreset ; USER=andy LOGNAME=andy DISPLAY=:0 XAUTHORITY=/var/lib/xdm/authdir/authfiles/A:0-dd I5Wn PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin SHELL=/bin/sh HOME=/home/andy Nov 16 13:33:12 efi kdm: :0[14494]: pam_unix2: session finished for user andy, service xdm Nov 16 13:33:12 efi kdm: :0[14494]: pam_mount: received order to close things Nov 16 13:33:12 efi kdm: :0[14494]: pam_mount: real and effective user ID are 0 and 0.

Can somebody reproduce this error? 2. How can i turn off this error? I think about an programming error in pam_mount.so, but i dosen't know, how to debugging something like this. An ulimit -c 200000 seems not working at an *.so.
