I just updated my system and when I now login, Plasma does not start until a few minutes have passed. All programs that were open when I shut down the PC still start immediately, I can also access a terminal and issue commands. Most notably, mpd.service and mpd.socket are started and running (checked with systemctl status), but my client can only connect to it the moment Plasma starts up, which confuses me a whole lot and I cannot find a solution, so help and tips would be appreciated
There is an option enabled on KDE Plasma by default is “Session Restore”, if you set it to “Start with an empty session”, it should fix one of your problems.
I found out that the problem only happens on boot, if I log out and log in again everything functions as it should, task bar is there instantly, and my mpd client can connect to the socket immediately.
Can you check output for systemd-analyze and systemd-analyze blame, If they look normal.
You can try disabling plymouth and plashma splash screen. They might show any logs or warnings. Also, don’t forget to check if there is anything on Autostart from settings.
