Bug Description
Version: Ubuntu Gnome 14.04, trusty
Laptop: Asus U36JC
I am currently using gdm version from "ppa:darkxst/
If there is only one display (the built-in laptop monitor), gdm works fine without any problems. If I plugged in another VGA display at boot time, gdm will flicker between grey and black (off) background without showing any text and buttons etc... gdm becomes useless at this state.
Workaround: Login to gnome-shell with one display first. and then plugged in the second VGA monitor. gnome-shell works fine with multiple monitors.
