Am running KDE on my laptop and every time that i connect an external display, all my open windows move over to the external display and i have to manually bring them back to the default laptop display.
Any suggestions/ solution for this?
I don’t know anything KDE specific but I guess you have a similar functionality - which can set the primary display.
It exist with Nvidia and XFCE and most likely you will have something similiar.
I have already set my laptop screen as the default and external as secondary but still the same same thing happens.
