X Window with GNURoot I have installed GNURoot (Fedora flavour) on my Samsung Galaxy Note Pro 10.1 (2014 edition). I am trying to get GUI applications to work (gvim, for starters), but I've been unsuccessful so far.

I've tried several X Window apps, but I don't undersand how to connect to their display (all I found were instructions for the applications started on a Linux PC, not locally under GNURoot) and I tried installing XOrg under GNURoot.

I'm an Android beginner (this is my first "smart" device ever), so I might be missing something obvious or I might be searching in the wrong places. Also, because I am a beginner, I prefer to avoid rooting and installing Linux properly (for now).
If you install Pelya’s XSDL Server from Google Play, you can use X11 aplications. In GNURoot type:

apt-get install xfce4

It will install the XFCE4 Desktop Environment and Xorg with some utilities.

And after several minutes of packages downloading and making configurations, start XSDL and set your favorite display resolution and zoom, and then type in GNUroot:

DISPLAY=127.0.0.1:0.0 startxfce4

Switching to XSDL app, the XFCE4 starts and you can now use the graphical interface.

Some other things: 
* Change font size as in ordinary Gnome. 
* Moving a flat finger is same as click and drag, for resizing etc.
* I have to press the back button on the pad to get the screen keyboard displayed. This overlays lower part of X Window though.
* No terminal emulators seem to work properly. However, GNURoot can be used for that.
* Applications like Gnu Planner, gretl and Gnu Cash work without problems.
