How to use Xorg in TermuxArch?

[abicorios]

I need the Xorg for run my Java Gui code when I study the programming. I try my simple exercise https://github.com/abicorios/JavaGuiExercise by JDK, which I obtain by pacman -S jdk9-openjdk. As far as the error is No X11 DISPLAY variable was set, I use pacman -S xorg and pacman -S xorg-init. But startx produce errors too, and I cannot run my code. Also, how to connect the TermuxArch to the XServer XSDL? https://play.google.com/store/apps/details?id=x.org.server

Wow. It is work. After run XServer XSDL, just input in the TermuxArch console

export DISPLAY=:0 PULSE_SERVER=tcp:127.0.0.1:4712

And after it, I can start some Gui soft from the TermuxArch console.

I tried to install and run xfce4 with following commands:

    pacman -Syyu xfce4 xorg
    echo "exec startxfce4" > ~/.xinitrc
    export DISPLAY=:0 PULSE_SERVER=tcp:127.0.0.1:4712

but failed. Running startx outputs this:

Couldn't get a file descriptor referring to the console

I am probably missing something, probably it’s just the port number – how can I get that number?

You can see port nuber by 'XServer XSDL' app. Install it from https://play.google.com/store/apps/details?id=x.org.server
