GDM 4 XDMCP installed with no xserver.

Ohh I forgot... I can run an Xserver, but as I'm running under coLinux it would be useless.

thank you for your bug report but that seems rather a user debug request than a bug

Sorry, The documentation referances [serverStandared] or something and this should be in gdm.conf or If I add these things to custom.conf. No, I'm sure that by default you can't alter how the X server is started as this is being a bug.

Like a feature that was removed.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue that you reported is one that should be reproducible with the live environment of the Desktop CD of the development release - Oneiric Ocelot. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. You can find out more about the development release at http://www.ubuntu.com/testing/ . Thanks again and we appreciate your help.
