It is actually possible, yes and Yes, I have done it.
And yes, I am currently running it…
On My Samsung Galaxy s7 phone.
I would be happy to post pictures.
It is pretty entertaining to see a mouse cursor moving around on my phone screen and Whisker Menu.
But is it practical enough to go through all the work? Ah… That is the question.
That being said, there is an easier way.
Dex is good for Galaxy S8 or above. Do a ducksearch for Dex Samsung.
For other Android- (Check compatability in the Google Play Store) you may also check out “Debian No Root” app which works Very Well, too.
Another app that works quite well is Andronix; you must also install VNC Viewer and Termux alongside of it. You install teh distro you want using Termux. You MUST Read the documentation in order to problem solve and enable all the things to operate it. It is a bit heavy on the setting up but once up and running, it works very well. It is not as heavy an installation is what your OP requests.
Hope this helps.
