First of all, evince and auctex communicate over the session dbus for
forward/backward search.  And apparently your WM without a DE doesn't
start a session bus.

But that can be fixed, I think.  I'm not sure, but wherever you start
qtile (maybe from .xsession or so), you might want to try to start
"dbus-run-session -- qtile" instead.


That would fire up a dbus session and qtile, and then my hope is that
forward/backward search with evince work as usual.
