What's very confusing to me is the mixing of the client and server support.

Has the XDMCP support of the gdmgreeter been removed?
Has the XDMCP support of the gdm server been removed?
Have they both been removed?

I believe this report originally targeted the gdmgreeter and that is the only XDMCP support that has been remoced. A possible workaround for some users would be to use tsclient / xephyr as a client. Also the upstream comment: https://bugzilla.gnome.org/show_bug.cgi?id=592976#c1 claims that gdm 2.30 server should still be supported. In fact I am able to connect to Lucid by adding the XDMCP entries Enable=true and DisplayPerHost=2 to the custom.conf file on the server with start xephyr session from a Lucid client.

But I only can start a single session which sometime has interesting issues like button presses not triggering. Also once I disconnect I cannot reconnect to the server with the error message: "Session declined Maximum number of open Sessions from your host reached" This only happens when connecting to a Lucid gdm 2.30.2 server. Connecting to a Goddard gdm 2.30.2 allows multiple successive logins.

I also have issues connection to a Lucid gdm 2.30.2 server at all on one machine that was upgraded from karmic. But I'm not sure whether it's worthwhile to report these issues until it becomes clear whether XDMCP is supported as a gdm service in Lucid or not.
