starting gdm, but not X

[Ekkard Gerlach]

Hi, 

how can I explain gdm to start without starting X? 

I'm using 10.04, xubuntu / ubuntu. 

Why? - xubuntu is running as vserver and X can't be started, 
gdm seems to crash after about 20 sec trying to start X. 
But ubuntu in a vserver environment can never start X ... 


root at xubuntu104:/etc# service gdm start
gdm start/running, process 10097

root at xubuntu104:/etc# ps ax | grep gdm
10211 ?        Ss     0:00 /bin/bash /etc/gdm/failsafeXServer
10226 ?        S      0:00 xinit /etc/gdm/failsafeXinit /etc/X11/xorg.conf.failsafe -- /usr/bin/X -br -once -config
/etc/X11/xorg.conf.failsafe -logfile /var/log/Xorg.failsafe.log
10232 pts/3    S+     0:00 grep --color=auto gdm

Is gdm running?
After about 20 seconds the gdm disappears automatically from process list:

root at xubuntu104:/etc# ps ax | grep gdm

root at xubuntu104:/# cat /etc/X11/xorg.conf.failsafe

EndSection


/etc/gdm/custom.conf:
