Re: [gdm-list] telling gdm to manage my own servers

[Brian Cameron <Brian Cameron Sun COM>]

Paulo:

I'm not sure this is possible without hacking GDM to a degree.
You can't run gdmgreeter or gdmlogin by hand because these
programs talk to the daemon using stdin/stdout pipe so the
daemon really needs to start the greeter.

You might be able to setup your GDM configuration to run
some phony Xserver that will trick GDM into thinking it
started the Xserver.  Or you might be need to hack GDM to
skip the "start the Xserver" step.

The gdmdynamic command is designed to start Xservers in a
dynamic way, though I think it assumes that GDM does the
job of starting the Xserver...but you might want to add
an option to gdmdynamic to make it do what you want since
it is very similar.
