Hello, I just upgraded to xdm 4.3.0.dfsg.1-9 and after a restart my window manager won't come up. So I read the xdm log and found out, that sessreg wasn't called correctly. In /etc/X11/xdm/Xstartup at line 24 there is missing an "\" at the end of the line. So not all parameters where passed to sessreg. The correct line must be: exec sessreg -a -l "$DISPLAY" -u /var/run/utmp \ -x /etc/X11/xdm/Xservers "$USER" Could you please verify that? Thank you. Sven
