I have a fresh install of Fedora KDE Plasma Desktop 40. Every time I log into the DE, the Discover application opens automatically on start. How can I disable this behavior so that Discover does not automatically launch? There are no apps configured for autostart in the KDE autostart system settings.
I had the same issue, I went to Session settings and disabled session saving. I can’t remember the exact names of them but I think that you’ll find it.
That did it! Thank you!
My solution: Desktop Session - System Settings > Session Restore > Start with an empty session
I could probably alternately add the Discover app to the Ignored applications list, but I prefer a fresh session on start.
Glad I could help! I only found out how to solve it today. Funny that I could use the knowledge immediately too.
