Thanks for the "not accelerated?" clarification.

I also tested Greeter Background loading with these two options,

a) Option "AccelMethod" "none" - works.

b) Option "AccelMethod" "glamor" - works conditionally,
with:
Xfwm4 - Xfce4 window manager
- enabled display compositing
- enabled synchronize drawing to the vertical blank

when 'glxinfo' starts, X crashes:

X.Org X Server 1.16.3
