Created attachment 107927 [details] System setting for default monitor/view Distro: KDE Neon Developer Edition Git-Unstable from 19th August 2017. Plasma: 5.10.9 KDE Frameworks: 5.39.0 When two (possibly multiple) monitors are attached, the setting of a main display that is not the main display chosen by either BIOS or the OS in general but rather set by the user in the system settings (see attached image), kscreensaver only uses the the chosen monitor/view, when the user is signed in and the screen gets locked (this behaviour can be tested by seing which password input field gets the focus). However, when starting the OS and when signing the user off - and therefore, the ksreenlocker is shown - kscreenlockers seems to order the monitors according to either BIOS- or default OS setting. IMO this behaviour is inconsistent. Is there a way to globally set a default monitor?
The "primary display" is only meant for where the panel goes. It doesn't have much meaning, especially not for kscreenlocker. Which screen gets the active password field is pretty much random.
