I remember having to do something similar when I was running a Debian chroot on an Android phone on one of the early Android phones.

Haven’t stuck around so I don’t know if VNC is still common to use locally on Android when you want to run other Linux distros with graphical environments on your device.

It worked but having to rely on VNC for something that is local on the same machine never felt great to me. Same when I VNC into a VM on the same host. It just feels a bit wrong to me to have to use VNC. It works and I do it sometimes for VMs on my computer, but I don’t like it.

The cool people do things like PCI passthrough. But I don’t have an extra graphics card and I haven’t looked much at the details of PCI passthrough anyways. Seems like a lot of effort also.

I do like X11 forwarding. I don’t know what to do for Wayland when it’s a VM.
