KDE PLASMA: Slow login to desktop?

Question

I'm a new kde user so i hope anyone helps me.

My problem is, session starts very slow i don't know why ??

I have a lenovo core i5 , 8 gb ram ,hyperX ssd , and i'm installing Antergos with Kde Plasma desktop

Systemd output is so perfect:

Startup finished in 4.904s (kernel) + 1.485s (userspace) = 6.389s

On Desktop session:

1. Default leave is Turn off computer

2. on Login is Start with an empty session

Polkit Status:

polkit.service Active: active (running)

so any suggestion please.

Thanks you all.

Answer 1

I had to unplug the HDMI and kde plasma 5.10.2 login with arch linux took only 4 seconds. With HDMI plugged in, login took 23 seconds. This is the only answer I have found to date.
