Today GDM 3.2.1 seems too hard to maintain on personal PPA anymore... :(
Yeah in fact Fedora17 would be released "completely without any ConsoleKit" but providing "Systemd" as new features... So now git branch goes along with this change dramatically from a couple of month ago. In opposite, Ubuntu still needs ConsoleKit even if it has some security disadvantages... Additionally, Gnome-Keyring has been updated to 3.3.92 as well.
Exactly today my gdm-3.2.1 have broken on Precise Pangolin with latest gnome-shell codes. On meantime, I've tried "tons of" patchworks while keeping ck for gdm-login routines, but still no luck... :(
I won't make any security-holes by dirty hacks, and now lightdm seems well on multi-display configurations, on user-switching, and so, even though we might have to make some new greeter to fit to gnome-shell's appearance and/or Look&Feel... I wonder it might be even easier than keeping gdm3 alive in the future of Ubuntu...
How it should be...?
