How to use framebuffer video option on modern android?

[ffpp2003]

So far I was able to install Debian 11 with xfce and using Xserver XSDL 1.20.52 app, but I'm having a hard time moving through the UI (even with 2x scaling) just using my fingers. Not only that but the Xserver is king of buggy/unstable. Once I start the app in a specific orientation, switching orientation produces stretching of the image and some other artifacts. Not only that but some apps seem to render out of the screen when in vertical mode.

That's why I wanted to try to use framebuffer as the video output, but after looking at /dev, there was no folder named graphics and no files named fbX, so I'm kind of lost now.

I'm currently using Linux deploy on a Xiaomi Mi 9 lite (sdm710) running EvolutionX 7.9.2 (A13)
