In the case of "flexible" I see also the custom setting:
... server-Standard0/flexible=false <custom>

I do that with '/etc/init.d/gdm stop' via ssh.
Then I check if gdm is running with 'ps aux | grep gdm'.
Then I start gdm with '/etc/init.d/gdm start'.

I have removed the 'vt7' and 'vt8' from the command's in the gdm config,
but display :0 still does not show a visuable gdmgreeter.

I told before that Xorg did not start on :0. That was wrong, Xorg does
start, but directly a program (gdmgreeter, I expect) is starting what
creates a blank screen.

When I do a "ps aux" (via ssh) I see 2 gdmgreeter's running, but the
gdmgreeter on :0 gives only a blank screen. On :1 everything is OK.

So far I know I do that. When I turn off :1 then :0 works fine.

gdm.conf: http://server.vandervlis.nl/xorg.conf5
xorg.conf: http://server.vandervlis.nl/xorg.conf5
syslog: http://server.vandervlis.nl/syslog5
Xorg.0.log: http://server.vandervlis.nl/Xorg.0.org5

I don't change this file, but it can be important:
defaults.conf: http://server.vandervlis.nl/defaults.conf
