I also rebuilt Maverick's GDM keeping the --enable-ipv6=yes option and bringing in the 03_ipv6.patch patch from Debian as mentioned in #96 from http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=579033, grabbed from Debian package version gdm3_2.30.5-6 (build available in my PPA here: https://launchpad.net/~tellis/+archive/customer1/+packages).
This works as expected, XDMCP session is successful but gnome-session/panel's are not appearing until I log in via XDMCP for the 2nd time.
I also carried out some verification with 10.04 using GDM 2.30.2.is.2.30.0-0ubuntu4 - XDMCP is working perfectly.
To summarise:
Ubuntu 10.04 - GDM 2.30.2.is.2.30.0-0ubuntu4 - Remote XDMCP successful Ubuntu 10.10 - GDM 2.30.5-0ubuntu4 - Remote XDMCP connections fail Ubuntu 10.10 - GDM 2.30.5-0ubuntu5-ppa1 with --enable-ipv6=no - Remote XDMCP connections successful (but no gnome-session until second login attempt) Ubuntu 10.10 - GDM 2.30.5-0ubuntu5-ppa2 with 03_ipv6.patch from Debian - Remote XDMCP connections successful (but no gnome-session until second login attempt)
So, for 10.10, it looks like pulling in the ipv6 patch from Debian would solve part of the problem and for 10.04 I don't see an issue.
