A user on reddit recently asked how to quick tile a window when it opens in a multi monitor setup. While they could easily position the app using a KWin Rule, that solution would only work for a single monitor. As if you launched the app on the 2nd monitor, the app would always show up on the 1st monitor.
When KWin Rules fails, you can write a KWin Script!
Then paste this in the
That’ll define the name/icon of script that shows up in System Settings. Make sure
X-KDE-PluginInfo-Name=QuickTileAppOnStart uses the same name as the folder you place it under. Next up is the actual script.
Then in the
firefox to whatever “window class” you’d use in a KWin Rule to limit this quick tile effect to a single application. Otherwise remove the if statement.
Finally, open up KWin Scripts in System Settings, enable the script and hit apply. If it doesn’t work and you edited the
main.js, to “reload” the script, disable the script, hit apply, then re-enable the script and hit apply.
