The check box for this settings was infact already checked. So maybe if I change what happens when I close the lid, from sleeping to hibernation or something else this could fix this maybe?
Ah, I see. Guess you may as well give that a go. I’m guessing what might be going on here is KDE doesn’t count it as a media player for whatever reason. Are you using Jellyfin in a browser or with the dedicated Jellyfin Media Player app?
