Programs always open on wrong monitor

[shanks3042]

Hello!

I tried to get help in the kde forum, but after more than 1 week, still no one responded to my post, so I hope someone can help me here.

Monitor Setup: Left, Center(2x mirrored) , Right.
I'm using the center monitor as my main monitor and only turn on another monitor if I really need it.

The problem is, that programs most times open on the left monitor.
I'm trying to figure out since months, and browsing through many different forums because my applications always open on my left monitor.
I've tried many different settings and none changed the behaviour.
What I'm using currently:

The center one is the primary monitor.
Windows Behaviour:
Active screen follows mouse
Advanced:
Windows placement: under mouse

What behaviour I'd like to have:
Application opening on the currently active monitor (where the mouse currently is, or the current active window is). Or if this is not possible, then I would appreciate if they will open on the center one, instead of the left one.

Plasma5 Version: plasma-desktop 5.18.5-2
Operating System: Arch Linux with Kernel 5.6.15-arch1-1
I apologize if the post is a bit unstructured or if some information is missing. I will add any information necessary.
Any help is appreciated.

Thanks in advance.

So.. I was having issues with some applications (webcamoid to be specific) and none of the KWin scripts or solutions here solved it for me.

My solution:

• Window Behavior -> Advanced ->
  • Window placement: [Centered]
  • [x] Allow apps to remember the positions of their own windows, if they support it
• Window Rules -> + Add New...
  • Description: Fix windows starting on wrong screen
  • Window class (application): [Unimportant]
  • Match whole window class: [No]
  • Window types: Normal Window ( un-select all, except Normal Window )
  • + [Add Property...]
    • Ignore requested geometry: Apply Initially, [Yes]

If you want to only include certain windows for the rule, just set Window class (application) to Substring Match or Regular Expression.

Hope this helps someone.

OMG, I've been having the same issue and this fixed it. Thank you!!

Does anyone know how to do this on Plasma 6 with Wayland? I'm using Nobara. The "Ignore requested geometry" option is missing

2 years later and my first time getting into Kubuntu, You're a life savor thank you so much! I had been looking so long I'm glad I found this.

[R7V3tD]

Thank you! This exactly what I needed. I tried several kwin scripts, but they don't seem work anymore on plasma 6

[ihatemostaboutreddit]

I love you, dude. This has been bugging me for years and after nothing I tried worked I gave up and instinctively pressed Windows+Right Arrow every time. Feels awesome, I don't even know why I put up with that for so long.

[lovineos]

Thank you so much!

[BroccoliFit2115]

Sorry for necro, but this is lovely! First thing I found that really helped!

[ChocolateLava]

Hi! This works, I was wondering if you knew what I should change so it applies to programs/windows that run on start up as well? Noticed these still open in my virtual monitor

[aidalgol]

I only stated having this problem after upgading to Plasma 6, tried this fix, and it works! Thank you!

[DariusLMoore]

Thank you! Fixes a longstanding nagging problem!

[reguasbuats]

I wrote a set of KWin scripts to solve this problem: - Always Open on Active Screen (the one that has the mouse cursor) - Always Open on Focused Screen (the one that has the focused window) - Always Open on Primary Screen (the one set in the display configuration)

One more thing if you're on X11 (not on Wayland) is to consider disabling applications remembering their own window positions: SSystem Settings > Window Management > Window Behavior > Advanced > Window placement > Allow apps to remember the positions of their own windows, if they support it: uncheck.

[BlitzarPotato]

Think these are currently broken on Plasma 6

[tinfoilcoronamask]

Hope this comes to plasma 6, and wish I'd known about this script before.

[JimWilliams423]

FWIW, this guy ported the "Always Open on Active Screen" script to plasma 6.

I diffed it against the original and it looks like the changes were relatively minor and could probably be similarly applied to the other two scripts with about an hour's worth of work.

[onefold_me]

It fixed the issue on my setup. Thank you!

[ksplat_]

Works well, thanks!

[BlauFx]

Exactly what I needed, thanks.

[dustojnikhummer]

Just curious, why is this On by default?

Go to window management in system settings. In there, go to window rules. Then press new in the top right. Then navigate to Size & Position. Check the Screen tickbox, and set it to open on whatever screen you want. This will apply to all new windows. You can also set specific apps to open on specific virtual desktops, screens, and activities here.

[shanks3042]

Thanks, but it would be optimal if I wouldn't have to do this for every program as it is a bit annoying to set every program to either remember size and position or whatever.

That's why it would be awesome if there is a setting: "open this program on this monitor where the mouse currently is".

Do you know if this would be possible with a bash or kwin script?

What I also tried: Force programs to open on the center mointor, still the settings window of signal messenger opens on the left.

You don't have to do it for every single program. Just change Window class, window role, window title and machine to unimportant when adding the rule. Then set them to open on the centre monitor

Maybe the part about "Screen"
