Window positions in KDE

I can’t seem to get the alt-m mixer to open up on the display that I want, maximized. Has anyone been able to set up window specific settings for Ardour in KDE? I have 2 displays, and I want the mixer to open on the primary display, and the main window on the secondary display…thanks in advance!

strange. I have a dual display as well and the windows always open where they should. I have done nothing particular. When I create a new session, I open the different windows I want and place them where I want too. When I save the session and reopen it, windows are placed correctly where I saved them.

yeah, mine will open on the right displays, but the mixer isn’t the size that I left it. Also, I want the mixer to ALWAYS default to the primary display, even on new projects…usually I just right click on the window border and go to advanced:special window settings and make the setting their, but it doesn’t seem to work…
