Does that mean it should be possible sometime 'soon' to run xwayland
-> wayland -> SurfaceFlinger?
I've not seen any xservers that work on android as yet; and I'd really
really like to use x2go or one of it's ilk on my galaxy tab.
vino's screensharing/console attach is rather broken in recent
ubuntus, xrdp's never worked quite right;
so the only options one has right now is good old xvnc/tightvncserver
running it's own unique X display, and performance is predictably
horrible unless you drop down to heavily compressed 8-bit.
