data: fall back to old greeter if gnome-shell not installed (1.11 KB, patch)

Description Jeremy Bicha 2012-08-30 21:28:59 UTC 
I tried using GDM without having gnome-shell installed. Upon booting, the screen stayed black and I couldn't log in at all.

What should happen: GDM should recognize this case and use its fallback mode.

I worked around this in Ubuntu by having gdm depend on gnome-shell, but that's not the best solution.

I've pushed a simple fix for now, but we may want to add a TryExec type key to the gnome-session file format.

The following fix has been pushed:

data: fall back to old greeter if gnome-shell not installed

Some users use GDM without having gnome-shell installed. Upon
booting, the screen stays black and those users aren't able to
log in at all.

What should happen: GDM should recognize this case and use its
fallback mode.

This commit fixes that.  Suggestion by Jeremy Bicha.
