I have been trying several options (gui tools, manual changes of the config files, etc) but I have never found a real solution. And it happens with or without the native Nvdia drivers loaded. The only point I'm sure is that I did not have this issue with OpenSuSE 13.1.

Hi Marco, If your setup is like mine, you have one display connected through the card's HDMI port and the other connected through the VGA (or DVI) port, correct? Have you invoked On Screen Display (OSD) in each external display side by side to ensure that they are configured _exactly_ the same? Does the problem persist if you swap just the displays left <> right?

This could be caused by a disparity in the way that 'power save mode' is handled on the VGA/DVI side vs. HDMI. Maybe a good place to start is to turn off all power saving features, in KDE as well as in the displays (if so equipped,) and to also disable the screen saver. Once this has been accomplished, both displays will simply stay on all of the time (and the window 'migrations' will be avoided.) It might then be possible in KDE to enable just the screen saver, or just 'power saving mode,' and see if the window 'migrations' problem is solved. hth & regards, Carl -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
