[SOLVED] Dual Monitors

Hey guys. Been a linux user before, but I'm pretty new on Arch. Been on it a month already. So far so good, just one tiny problem while gaming.

I know there are lots of post related to this topic, but I think solved ones are specific related to that hardware set.

The issue I got it's when switching from one monitor to another inside the game. After some time playing the character camera usually glitches. Can't move it with my mouse and can only move my character with the keyboard. Don't know what's causing. Never had that problem on Windows.

Anyway here goes my system:

OS: Arch Linux x86_64
Kernel: 6.8.1-zen1-1-zen
DE: Plasma 6.0.2
WM: kwin
CPU: AMD Ryzen 5 5600G with Radeon Graphics (12) @ 4.464GHz
GPU: AMD ATI Radeon Vega Series / Radeon Vega Mobile Series

I'm using Wayland btw.

And screens:

HDMI-A-1 connected primary 1920x1080+1920+0 (normal left inverted right x axis y axis) 950mm x 540mm
DP-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 600mm x 340mm

2nd is connected with VGA port. Desktop only has one HDMI port which is the one I use for gaming.

Hope you can help me out with this one. I usually don't post in forums for this kind of stuff.

Re: [SOLVED] Dual Monitors

What "game"? Steam? Did you try the behavior in an X11 session?

Re: [SOLVED] Dual Monitors

I do play most of my games via Steam. Mostly all games that have a camera moving with mouse (sometimes they react different but all glitch at some point). Lutris didn't fix it and haven't encounter any need for it so far.

Yes, X11 is the same. Was using it before Wayland. For some reason, Wayland keeps better track of customization changes.

What "customization changes"?

Maybe re-test X11, it's a known problem w/ kwin/wayland but works for everyone on X11…

Re: [SOLVED] Dual Monitors

Thanks Seth. Think it's solved by now. X11 wasn't saving my desktop settings for some reason, now it does.

And for the camera glitch, it seems like "yay -S preload" did the thing.

Been playing the whole day without issues so far.

Re: [SOLVED] Dual Monitors

X11 doesn't store anything, it'll apply the present config or, by default, activate all present outputs when the server starts.
Your session (KDE/kscreen) however will.

Likewise merely installing preload probably won't have done anything,

systemctl status preload
