gdm doesn't respect $PATH, hardcodes X location

[Fabio Valentini]

Description of the problem:

- LightDM as display manager: X from /usr/local/bin/X is used, just as it should, according to the $PATH env variable defined in /etc/environment. Everything works fine with LightDM.

- GDM as display manager: X is always used from /usr/bin/X, and $PATH is ignored. It seems that the location of X is hardcoded somewhere. If I move /usr/bin/X to /usr/bin/X.bak and restart GDM, it fails to start and doesn't find X in /usr/local/bin.

I am using ubuntu quantal, my packages are up-to-date and I compiled X from upstream git master on fd.org.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.
