Bug#605658: gdm: Xsession gets DISPLAY=:0 even when server is :1

[Marc Lehmann]

Package: gdm
Version: 2.20.11-2
Severity: normal


(This might not be a bug in gdm, but it manifests only with gdm for me).

When starting gdm when a server is already active on :0, gdm shows a console
dialog asking me whether I want to start a server on display :1 instead.

When answering yes, it does so, but when logging in with a GNOME session,
the session immediately exits.

Analysis shows that DISPLAY is set to :0, so gnome cannot open the display.

Adding DISPLAY=:1 at the very top of /etc/X11/Xsession makes it work,
proving that DISPLAY was not set to :1 when it was invoked.

Obviously, gdm should either not offer the option of starting another
X-server or, maybe preferably, it should actually work.

Greetings,
