For some reason, in order to switch my wallpaper, I need to reboot my pc every time, and if I am not doing that, it will just mark the wallpaper I chose as "selected", but won't actually change until I reboot.

Is there any solution to that?

  • Also a problem for myself. And having to logout and back in is not a tenable fix. Nov 13, 2018 at 17:09

The same problem was solved for Loki previously.

You have to restart (or at least reload) Gala to change the wallpaper. To do that, you can type or paste the following into Terminal:

killall -HUP gala

The -HUP flag tells the command to basically "Hang-UP" the gala process, which makes it restart.
