Monitor is slow turning on after shutting down due to timeout

I have this problem, where when artix is going to lock the screen it shoves me back to the login (sddm). When I take longer to fetch my coffee, artix is shutting down the monitor. And there is the problem. When I come back and wake him up it takes a loong time (up to a minute) to see the sddm login screen. I know it is not the monitor which takes so long, as on other OSes this process is way faster (a few seconds). So why is it the way it is? Is the shutdown from artix different than on other OSes? how can I configure this? Any hints are as always highly appreciated, but no, it is no option to fetch my coffee faster ;)
as always, correct me if I'm wrong ;)

I'm using SDDM on XFCE and also have a monitor that takes a bit of time to wake up.
I disabled system and screen sleeps and uninstalled xfce4-power-manager.
It's not perfect yet, but the screen wakes up a little faster when I right-click.

You disabled the screen sleep completely?

btw: I am using KDE Plasma here (forgot to mention this in the original post)

Yes.
My monitor puts itself to sleep to save power.

And cpufreq is set to conservative, but ondemand is fine too.

For openrc :
Code: [Select]
sudo pacman -Sy cpupower-openrc
(In principle you can configure '/etc/default/cpupower' but it doesn't work for me.)

Launch cpupower at startup:
Code: [Select]
sudo rc-update add cpupower

To occasionally modify the governor mode (example):
Code: [Select]
sudo cpupower frequency-set -g powersave

As I use XFCE4, I had the luxury of adding xfce4-cpufreq-plugin.
But the equivalent must exist for KDE.

Thank you for the detailed response. I will try some things out and see if it gets any better ;)
