XORG and Dummy driver compatible with Android

[Mgr. Janusz Chmiel]

Dear MR Anfimov,
Thank you very much for yours professional support.
But I AM sad, that external keyboard may be could not be used from AN x 
running app.
When I will type
export DISPLAY=:0
on Debian executed by using Proot, do you think, that Debian would be 
able to communicate with Xserver whichwill run on Termux?
Because Pulseaudio can be used by this way without issues.

It would be ideal solution. I would like to publicly thank all engaged C 
and C++ language programmers, who are making specific source code 
modifications so even XORG can be used on Termux environment.
Without yours hard work, Linux on Android would stay to be only Illusion 
and not The reality.

Termux have significantly changed my life. Because I Am able to use 
sound without distortion and system instability. And fortunately, there 
are many GTK compatible applications, which do not create shared memory 
files or shared executable stack.
Those apps including mate-control-center, many GTK window managers and 
even Pulseaudio havebuild in techniques to use normal memory pool 
instead of shared memory pool. Sure, developers have much more work to 
adapt their sources to support both modes.
