I have the same setup (EndeavourOS / KDE plasma 6 / Wayland / SDDM / 2 monitors) and had the same problem. The worst thing is that typing the password in the "active" login prompt (the one with the focus) wasn't working anyway, so I had to use the mouse to give focus to the other monitor first, and then type the password. Absolutely annoying.

The solution I found (sorry I forgot where, some forum) is to disable all the detected monitors except one in /usr/share/sddm/scripts/Xsetup. Basically your secondary monitor will not get any signal until you type the password and log in. At that point any other monitor will be reactivated automatically.

This is my Xsetup:

#!/bin/sh
xrandr --output DisplayPort-0 --mode 2560x1440 --pos 0x0 --rotate normal
xrandr --output DisplayPort-1 --off
xrandr --output HDMI-A-0 --off
xrandr --output HDMI-A-1 --off

IMPORTANT

Check out the output of xrandr in Wayland on my system:

$ xrandr | grep ' connected'
DP-1 connected primary 2560x1440+0+0 (normal left inverted right x axis y axis) 590mm x 334mm
DP-2 connected 2560x1440+2560+0 (normal left inverted right x axis y axis) 590mm x 334mm

DP-1 and DP-2 are the names used by Wayland, but they don't work in Xsetup because X11 calls the ports DisplayPort-0 and DisplayPort-1 - and I don't remember if HDMI ports are also called differently.

So you need to log in X11 first, get the names with xrandr, create or update Xsetup and reboot.

Democrats: "Either you vote us or you are fucked. And no you won't get what you really want (the end of the genocide, healthcare, whatever), but you can choose to eat out shit or the republican's. Are you happy with that? No? Fuck you and vote Harris anyway ah ah ah. You don't have a choice, we don't give a shit about you and your problems but you have to vote us. You have to."

You see, people are realising that their vote is useless by design, and maybe the only way to change something is to punish the party that pretend to be the good one, the one that pretend to be at your side and pretend to work for you but it really doesn't.

They are making you believe that democracy is just about preventing the others to get elected because they are worst. No it's not, and you should stop being a victim and do something, anything, to force them to change. Even if you get 4 years of Trump: whoever think that it makes a difference is delusional, he's just blatant fascist while Harris is secretly fascist. They are just two different seasoning for the same plate of shit.

Yes, the Taliban were armed and financed by USA.

Which mini pc? I have an Intel NUC Intel i5 and looking for something smaller but can run a dev desktop (xfce, vscode, node, docker).

We already know, you idiot: fascisms thrives when inequality is on the rise and capitalists feel threatened.

Lack of workers rights, as usual. In (most of) Europe those monitoring systems are illegal, as it should be.

The fate of consoles is to be cloud-only. You will own nothing and be happy.

Yes

The notorious land of the freedom.

Probably because its real purpose is not to sell things.

Also killing wounded/unconscious/incapacitated/hospitalised/trying-to-surrender enemies is a war crime. They just don't give a fuck because nobody stops them.

I'm confused, is he doing exactly what he said he would do?
