I've installed Cauldron on an older laptop I have because I wanted to look at Gnome 3.
I've noticed when I first boot the machine the login page is an older version of GDM and when I log in Gnome starts in fallback mode. However if I then log out, I get the new login screen and can log into Gnome 3 Shell.
So my question is - is this a known bug? I searched at https://bugs.mageia.org/ and couldn't find it, but it may just be that I don't know what to look for.
If it's something already known about and anyone can help me get it working I'd be most obliged. Or, if it's something I should log a bug report for?
From what I've seen in Cauldron, Mageia 2 is shaping up nicely.

Andrew.
