Xorg monitor calibration and Android devices

[Mgr. Janusz Chmiel]

Dear specialists,
My name is Janusz Chmiel. I Am visually impaired user with no sight at 
all. I AM very advanced so I have started to experiment with Userland 
variant of Debian stable ARM64 bit edition while using it on Android 
devices.
The Android kernel allow advanced developers, who have developed Proot 
to execute 64 bit code on ARM 32 bit cpu. And I have one big programmers 
plea to you.
Is it true, that XORG contain some monitor calibration routines, which 
can hardware severely corrupt touching display when using it on Android 
device? Or is it A fame?
If it can occur, please would you give Me some professional instructions 
which will prevent Me from getting my display corrupted when running Xorg?
Since Xserver XSDL complex C Android app do not implement all Xserver 
methods.
And I can not simply type startx to run my favourite desktop on Android.
I Am also very very sad, that there is no article, which would allow Me 
to configure Debian system which run in chroot container by using Proot 
to safely run Xorg.
Thank you very much for yours advices.
With warmest regards.
Janusz Chmiel
