[Bug 480695] [NEW] kdm (and gdm) does not start if /etc/X11/default-display-manager is not completely standard

[MagnusPI]

Public bug reported:

Binary package hint: kdebase-workspace

I upgraded from 9.04 to 9.10 and both kdm and gdm could not be started by init neither automatically nor manually with 
"start kdm".

The reason is that the script for upstart is too strict in checking.

My /etc/X11/default-display-manager was

#/usr/sbin/gdm
/usr/bin/kdm

and the script stanza in /etc/init/kdm (and /etc/init/gdm) contains

[ ! -f /etc/X11/default-display-manager -o "$(cat /etc/X11/default-
display-manager 2>/dev/null)" = "/usr/bin/kdm" ]

which fails writing an almost useless log in /var/log/syslog
Nov 10 10:24:20 to4ixl init: kdm main process (1135) terminated with status 1
Nov 10 10:24:20 to4ixl init: kdm main process ended, respawning
Nov 10 10:24:20 to4ixl init: gdm main process (1138) terminated with status 1
Nov 10 10:24:20 to4ixl init: gdm main process ended, respawning


I suggest changing the first line  of the script stanza to

[ ! -f /etc/X11/default-display-manager -o "$( grep -E '^/usr/bin/kdm'
/etc/X11/default-display-manager 2>/dev/null)" = "/usr/bin/kdm" ]
