Ubuntu 20.04 Dual Monitor Issues

[Your Majesty Padded Gamer]

So basically, space heaven upon starting the program from steam, will chose my none primary monitor instead of my primary monitor. And thanks to the limited video settings, I can't seem to force it to use the correct monitor.

I made sure to try other games, to see if this was an issue with the operating system and so far I have only seen this issue in space heaven. This happens both with boarderless on and off and in windowed mode as well as full screen.

Hi there.

Have you tried putting the game in windowed mode and dragging the window to the primary screen, and then trying to switch settings to fullscreen? Will it go fullscreen in the correct monitor now?

When it boots into full screen mode on my none primary monitor, it will ignore all changes to video settings. So I would have to restart the game after turning full screen mode off, in order to force it to boot in windowed mode the next time I launch the game. And then switch to full screen mode in order to get it to use the correct monitor.

When I get it to go into full screen on the correct monitor, the video settings will work as intended without needing a restart.

While this is a valid workaround, it's not an ideal solution. As I have to do that every single time I want to launch the game.

Hmm. Ok, can you specify the exact steps to get it to work in the correct monitor?

Is it launching or switching to windowed mode, and then dragging to the correct monitor, and then going full screen?

Or does it actually launch into windowed mode on the secondary screen, and when you switch to full screen it automatically jumps to primary screen without you dragging the window to the primary screen?

I am having the very same problem on Pop!_OS 22.04 LTS, Nvidia GTX 1060 6GB.
I want to display the game on my primary monitor but it always jumps to the secondary monitor when borderless mode is selected.

I tried your suggestion and dragged the window to the primary monitor, then switched to borderless mode, but the game then jumps back to the secondary monitor.

Workaround: Switch off the secondary monitor, then start the game. Switch the monitor back on. Of course this is not a viable solution to the problem.

Then next time I start the game it is back to the secondary monitor, so I always have to switch it off before starting the game.

Also when I deselect borderless mode, the game does not change to windowed mode but stays in fullscreen. Only when I then restart, the game starts windowed.
