I can confirm that gdm-setup is not working, though not exactly in the same manner as described here. Basically, when I run gdmsetup from the gnome menu, the window comes up for half a second and then vanishes.
When I run sudo /usr/sbin/gdmsetup from an xterm, I get a segfault. I use my own password, not the root password. In fact I have not enabled the root account on Dapper. -- gdm-setup not working in dapper https://launchpad.net/bugs/31180 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
