From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Do you know if it's possible to run a second session in a window? (lemmy.world)

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)?

Totally possible. It'll work best with Wayland thanks to nested compositor support, whereas on Xorg you'd need to use Xephyr which doesn't do hardware acceleration.

# Give the other user access to your Wayland socket
setfacl -m u:otheruser:rx $XDG_RUNTIME_DIR
setfacl -m u:otheruser:rwx $XDG_RUNTIME_DIR/wayland-0

# Open a session as the other user (note the trailing @, it's there to login in to the local machine)
sudo machinectl login otheruser@

# Start your DE!
WAYLAND_DISPLAY=/run/user/$(id -u yourmainuser)/wayland-0 startplasma-wayland

And tada! Nested Wayland session

Wow, that's so neat!

On my machine it opens a fullscreen plasma spash and then it shows the new session intermixed/overlayed with my current one instead of in a new window... basically, it's a mess :D

If I may abuse your patience:

what distro/plasma version are you running? (here it's opensuse slowroll w/ plasma 6.1.4)
what happens if you just run startplasma-wayland from a terminal as your user? (I see the plasma splash screen and then I'm back to my old session)

Screenshot of said mess? Purley for entertainment 😄

I fear it was nothing that entertaining: it was just my "normal" dark panel at the top of the screen and a second "default" white one at the bottom (this last one partially covered the windows I had open). I didn't try triggering notifications or otherwise causing some kind of mayhem.
