Oh wow that's definitely weird lol
(It's the next day for me so now that's the weirdest thing I've seen today lol!)
Also nice with the Codeberg repo, I've been trying to switch my repos over to it cause it seems nicer than GitHub
Do you set the wallpaper from your profile ?
I've only tried 9 on a remote system but image handling was painfully slow so I gave up on setting the wallpaper from the Rio theme. Maybe that's faster locally on bare metal ?
Like any other operating system, really: by downloading the appropriate installation media and creating a bootable USB stick to install from. After reading the FQA and other documentation, of course.
rio is the window manager for Plan 9. People have created patches for other window managers like dwm that attempt to mimic some of rio's key features such as window "swallowing" and the ability to draw new windows by simply clicking+dragging with the mouse.
If this is your first time ever encountering Plan 9, I would highly suggest watching some of the videos by adventuresin9; they're a solid intro to what the whole deal is with Plan 9.
Is this in a VM or on actual hardware?
This is bare metal, specifically on a Thinkpad T420. It is my current daily driver.
