Sorry, I'm just a Linux user, how could I write such a standalone
program?

Sorry again, but I have very limited space left on the small ssd of the
eeePC, and compiling gdm should require to install a lot of *-dev
packages...
However, being "/usr/sbin/gdm --config=/etc/gdm/gdm-cdd.conf" the
command I can read when I do:
$ ps ax | grep gdm
12108 ? Ss 0:00 /usr/sbin/gdm --config=/etc/gdm/gdm-cdd.conf
12109 ? S 0:00 /usr/sbin/gdm --config=/etc/gdm/gdm-cdd.conf
I've tried what follows:
# strace /usr/sbin/gdm -nodaemon --config=/etc/gdm/gdm-cdd.conf >

If perhaps the output I've pasted here is not enough, I attach the
bunzipped file (just 13.3kB) with all the output, hoping it should be
useful...
