After I launched some program I need from an app image, it starts every time I log into system.
Going by Windows logic, there may be some menu or a queue that lists all apps that start after logining in with an option to disable it.
I’m struggling to find anything like that.
Yes but there should really be a menu where the autostart apps are. KDE Plasma has one.
They are in
~/.config/autostartIronically on Windows apps can autostart without being in the specific folder.
