Desktop here is the same, MATE Desktop on top of Linux Mint 22.3 XFCE Edition. Same background. But I wanted to showcase how it looks when I plug in my guitar.
This is Guitarix, and it sounds pretty welll as long as your guitar has got good pickups.

I have a folder full of cool pics that I’ve gathered over the years, and I change my wallpaper every so often.
