This is probably why you are getting the blank output.. if
initialization of the Javascript code fails, nothing much will show up.
Why this is, I have less of an idea. signals is shipped along with gjs.
Does:

 ~/gnome-shell/install/share/gjs-1.0/signals.js

Exist?

This is normal for start-in-Xepyhr. This certainly needs to be fixed to
warn only once.

An R100. I expect performance to about like compiz - not pleasant to
use, but should come up. Amount of video memory matters quite a bit. In
any case, I think your problem is the Javascript error.
