[raiguard][2.0.27] Factorio starts on the wrong monitor. (Linux)

[Mighty_Pig]

To start with I am not sure if this is a bug with factorio or just something wrong with my setup but since I've only had this issue with Factorio so far I suspect it has something to do with Factorio. If it is on my end you can move this topic to the technical issue forum.

For some reason factorio starts on the wrong monitor. As you can see here according to factorio it should be on my main monitor (1)

But if you take a look at the configuration

This should mean it should be located on the right monitor (Dell S2721DGF). But for some reason it is located on the left monitor.
When I select the prefered monitor instead of 1 *most* of the times it moves to the correct monitor (1). Sometimes I have to select the second monitor in order to move the game to the correct monitor.
I also noticed a few versions back whenever I moved it, it sometimes would start flickering and crash the game, but this seems to have been resolved.

Heres the log. This time I had to select the second monitor instead of the prevered one.

Some extra info about my setup:

Code: Select all

Linux Lithium 6.11.7-arch1-1 #1 SMP PREEMPT_DYNAMIC Fri, 08 Nov 2024 17:57:56 +0000 x86_64 GNU/Linux
nvidia-open 565.57.01-3
plasma: 6.2.3-1
Wayland: 1.23.1-1

I am also using the following launch option:

Code: Select all

SDL_VIDEODRIVER="wayland" %command%

if you need any more information let me know.

Update: I tried to use the fix below, but for me it doesn't fix the problem.
The given log is from version 2.0.18, however I am still experiencing the issue on 2.0.21, 2.0.22, 2.0.242.0.27 so the titled has been updated.

You're using KDE plasma, right? I get the same issue in 2.0.15 but you can make a Window rule for Factorio, in order to force it to your preferred location. It's in the system settings, as seen as below.

You can use the "Detect Window Properties" to get the proper information about arbitrary windows (not just Factorio) and then build your rules from there. I've also included a factorio.kwinrule file to my post (rename it to remove the .txt suffix if you want to import it easily).

Yes I am, thank you for this info. Haven't tried it yet.

But I still wonder where the cause of the problem is. For now I'll leave it open in the bug report even if this solves it since it's just a bandaid to the real problem.

This happens to me also, using KDE Plasma 6.2.3 on Nobara Linux 40 (Fedora 40).

So I went through the bug reports one more time and I noticed this bug seems to be reported already, and also already assigned, however no fix has been implemented so far. But I'll link those other assigned bug reports in here for tracking sake.
116349 I had the flickering at the beginning of the 2.0 update, but this seems to be fixed tho. Just noticed it also says it has been fixed, however it wasn't moved to fixed bugs (yet)

Edit:
It might be a issue with sdl2. https://github.com/libsdl-org/SDL/issues/4827
Seems seems to be very similar to what we are experiencing as far as my knowledge goes. The problem should be fixed once Factorio upgrades to SDL3.

Unfortunately, Wayland does not have a proper concept of what the "primary display" is. SDL3 has a convenient function to query the primary display based on several criteria, but SDL2 does not have this.

Plasma users can use the posted workaround in the meantime.

Thanks for the info. Any idea how fast Factorio might update to SDL3? It seems the first official release of SDL3 (3.2.0) is planned for January 15th.

There are several blockers:

* SDL3 needs an official release (apparently on the 15th).
* Nintendo Switch port of SDL3 needs to be updated.
* We need to perform the upgrade and do thorough testing of all systems.

So it will be a while.

Okay thank you once again! It's just a minor issue that I wasn't able to solve with the mentioned issue, however with the shortcut of the super + shift + arrow keys I can just put the game onto the correct screen very easily. So I can definitely wait a while .

Hello, thanks for your input.
FYI SDL3 is now released : https://github.com/libsdl-org/SDL/relea ... ease-3.2.0
That would be awesome to have it
There's even a migration guide SDL 2 -> SDL 3 : https://github.com/libsdl-org/SDL/blob/ ... gration.md

I tested the SDL3 "GetPrimaryDisplay" function and it doesn't appear to be any more reliable than our existing Vulkan method. The reality is that Wayland simply doesn't have the concept of a primary display and Factorio trying to specify a display to use is never going to work well on it.

I may just axe this feature entirely when on Wayland and leave it up to window managers / desktop environments to position the window where they want.
