[Linux] Mouse focus issue

[evilny0]

I have a multiscreen setup. When the game starts, it starts on my main monitor (which is quite rare actually for games, they usually start on the left monitor and I have to move the game window to my main monitor), but the mouse cursor is moved to the left monitor and the game window is minimized.

I can (usually after a couple of tries) bring the game window to focus by clicking on it in the window selection bar, but the mouse cursor is then again sent to the left monitor (and the game window minimized...) as soon as I move the mouse on the game screen.

The game is playable with a controller though (if I don't move the mouse!), so it's not SUCH a big deal, but it's still annoying. Dunno if it would be better with keyboard+mouse, but it's enjoyable enough with a controller :).

This happens if I set the game to fullscreen, or to windowed-fullscreen. It does not happen when set to windowed mode, but who wants to play this kind of game windowed :).

Any idea to fix this ?

I had another issue related to dual monitor setup with a different game under linux. Do you necessarily need both monitors on during gaming? Because you could just turn the other off via software. So the game can only use one screen and you will probably have no issues.

I have written myself some scripts to turn screen on and off with key-presses because I have 2 monitor 1 projector setup.

#!/bin/bash
xrandr \
--output DP-2 --auto \
--output DVI-I-1 --off \
--output HDMI-0 --off

This turn everything but my primary screen connected to the display port off. I then have another screen to turn both on again.

#!/bin/bash
xrandr \
--output DP-2 --auto --primary \
--output DVI-I-1 --auto --right-of DP-2 \
--output HDMI-0 --off

This may work only on X not on Wayland

My 3rd script turns the projector on and the 2 screens down.

I don't NEED the other monitors, but I'm used to monitor (oh oh) different messengers & other stuff while gaming.

I also have xrandr scripts, but if I can avoid using them... it always end up somehow messing up other windows and workspaces.

With KWin you can create a rule for a program/window to appear on a defined screen.
Haven't tested that however because of lack of multi monitor setup here.

The problem is inside Unreal Engine and should be fixed in version 4.20. However, this game is released and you shouldn't expect the developers to upgrade the engine at all, this won't happen since it's a lot of work.
