I tryed to create a UI for the Values, but could not find any usable documation about KWin-Scripts. Thats why you need to set the Values inside the ~/pkg/contents/code/main.js file.

Configurations:

• geometry.x:

Window-Position from the left most Screen.

• geometry.y:

Window position from top - If you have rotated screens or different resolutions (e.g. 1080p, 1440p, 1080p), you can centre it on the other screens. I have the left and right screens rotated left and right. This means I calculate "(1920-1440)/2=240" and with 240 pixels from the top the window is centred on left and right screen and full screen on the middle one.

• geometry.width:

Combine all screen widths.

• geometry.height.

The required maximum height of the window.

Dependencies

• KDE

• gamescope

Hotkey's:

SUPER + G = Gameing-Mode (GameWindow over all Screens, AlwaysOnTop(Off/On))

STRG + ALT + T = AlwaysOnTop(Off/On)

Starting Game's (Only Steam needs (%command%)):

• Normal:

gamescope -h 1440 -w 4720 -b %command%

• MangoHUD:

gamescope -h 1440 -w 4720 -b -- mangohud %command%

• MangoHUD with parameters (DOSE !NOT! WORK! HELP NEEDED!):

gamescope -h 1440 -w 4720 -b -- MANGOHUD_CONFIG=fps_limit=165,fps_only mangohud %command%

Creating the .kwinscript (You could also just use the file from the Releases on the GitHub-Page):

• Change the values inside the ~/pkg/contents/code/main.js to your Setup.

• Create a .ZIP with only the pkg folder in it.

• Rename it to "GamingMode.kwinscript".

Installation:

• In the KDE-Settings, go to the KWin-Script-Section and install the .ZIP.

• Enable it.
