When you launch a game on Linux with dual monitors connected, it usually tries to open on your primary screen. However, depending on your setup and display server, fullscreen mode does not always behave perfectly. The game might stretch oddly, open in borderless mode, or allow your mouse to drift onto the second monitor instead of staying locked where it should.<\/p>\n\n\n\n
With the right settings and a few simple tweaks, you can keep your game perfectly fullscreen on one display while your other screen remains fully usable. If you prefer an ultra-wide experience, you can also span the game across both monitors at once, using tools like Gamescope or by creating a virtual super-resolution monitor with XRandR<\/a> or Nvidia TwinView.<\/p>\n\n\n
