Choose on which monitor new windows appear in KDE

kdekwinmulti-monitorwindow-management

I am using KDE on Debian Jessie.

Whenever I open an application, it appears on the first (left) screen. How do I change this?

This happens with most applications. For example Vuze opens correctly on the monitor it has been before, but Double Commander (doublecmd) which I use heavily doesn't.

If it matters I have 3 screens. Left: FullHD TV (HDMI) + middle: QHD monitor (DisplayPort) + right: FullHD laptop display.

I found that only a handful of applications, including Double Commander, does show up on the non-primary left screen, on which mouse cursor is not. That would suggest an error in those applications, rather than a problem with window manager settings. I will contact such developers.

How to stop KDE from changing the screen resolution

There's a module in KDE called KScreen that is doing this.

To disable it, go to K Menu->Computer->System Settings->System Administration->Startup and Shutdown->Service Manager. Look for a service called KScreen, and uncheck the Use box. You can stop the service now if you want.

You can also manually edit $HOME/.kde/share/config/kdedrc, and add these lines:

[Module-kscreen]
autoload=false

This stops KDE messing with monitor configurations, and will stick with the one KDM provided at startup.

Kscreen is a per-user service; you'll need to set it for every user unless you have a policy set up.

Xrandr multiple displays showing different areas of the same virtual screen

I guess KDE may have something in it's settings to control this behavior. But if not, then you might try this

xrandr --output HDMI-0 --auto --output HDMI-1 --auto --{right,left}-of HDMI-0
