yes...you need to set some things up AFTER installation...
it isn't plug and play...
at least not yet....
But really now pichlo..feigning shock?
it isn't any different than running linux on chroot in android...
it isn't plug and play either.
you need to set some things up.
No different than needing to set some things up if you want even a half functional n900...after reflashing...
(well quasi functional n900 nowadays..)

and yes ...the TWRP for the standard install of PM is outdated.
I noted a few days ago (when I decided that testing and retesting and documenting everything and tracking back some issues was a sane idea)..
that it was one of a few contributing factors to some of the issues I was having....indeed ..some of the symptoms of which ...some in the nexus forum complain of having during and after install..I believe may stem from a few issues resolvable ..

Dealing with that and a couple other little things..
and the issues I was having seem to be resolved.
regardless ...I intend doing a bit more testing just to be certain I got everything buttoned up.

then my next priority will be finding some solution to the res to x11 prog disparity ..
then I will see about a different "skin" to the beast ...a different wm / de ...if it is manageable to implement..
then ...".."...(haven't thought that far ahead)
