It is specified in the [daemon] section by the "StandardXServer" key and
also in the various [server-foo] sections by the "command" key.  It is
probably the later which is being used in your case.  I'd check both.
More information is here:

You might also check for any leading white space in the keys.  That
might also cause a problem.

If the full path is being specified and there is no leading whitespace,
then the problem is likely something else.  Further review of the code,
or building it with debug enabled and attaching a debugger may be needed
to figure out exactly where the failure is happening.  My analysis is
just a guess based on looking at the code.

Different distros use different filenames for the configuration file.
The default setting is usually in /usr/share/gdm/defaults.conf, and the
values can be customized in the /etc/gdm/custom.conf or
/etc/gdm/gdm.conf file.

I have no idea what upstart means.  Different distros use different
mechanisms to start GDM, so you'll probably need to talk to your distro
to find out exactly how GDM is being started, and how the service is
being managed.
