I’m not much hoepful, but… just in case :)
I would like to be able to start a second session in a window of my current one (I mean a second session where I log in as a different user, similar to what happens with the various ctrl+alt+Fx, but starting a graphical session rather than a console one).
Do you know of some software that lets me do it?
Can I somehow run a KVM using my host disk as a the disk for the guest VM (and without breaking stuff)?
XWayland has something called a “rootful mode” where it opens an X11 session as a window nested inside a Wayland session. https://www.youtube.com/watch?v=Ij3rsqX2pKQ XWayland will be started as your own user, but maybe you could use
sudo -u ...
to set a different user.The other possibility is to switch to another terminal session with a different user, start an X11 session with
startx
, and usex11vnc -listen 127.0.0.1 -forever -passwd PASS1234
to run a VNC server that’s only accessible from the local machine.
