fedora 18 gnome-shell core dumps before live system starts

[Bram Mertens]

Hi,

For the VM on CentOS I found a solution: changing the video driver
from the default "cirrus" driver to xvga, after that the gdm screen
indeed showed a list of users.  Previously the error I got was
before/during the gdm so I never saw the gdm screen.

For the VM on Virtualbox I switched the displaymanager using
system-switch-displaymanager on the command line.

lxdm now offers me a username input field, nothing more.

I also used switchdesk to switch from Gnome3 to XFCE and that works.

Regards

Bram
