[Reposting to keep this searate from the discussion of what the default
settings should be]
This was discussed at one time (https://lists.fedoraproject.org/piperma
il/kde/2015-April/014478.html) but never got anywhere.
In brief: I use Session Restore under KDE. I have a number of desktops
and most windows are restored correctly on the correct desktops. The
ones that appear to have problems are non-KDE apps. Specifically:
* Firefox starts on the correct desktop but with the "This is
embarassing" error page. On clicking the button, the extra window
starts up correctly with all its tabs, but on the current desktop
rather the assigned one.
* Chrome doesn't start at all. When started manually, it fires up all
the correct windows and tabs but on the current desktop instead of the
I have manually configured the desktop settings for these apps, but of
course that assumes the app lives on only one desktop.
I am now on kf5-plasma-5.19.0-2.fc23.x86_64, using SDDM and Kwin. I'm
open to suggestions but have basically given up on hearing from the
developers (see https://bugs.kde.org/show_bug.cgi?id=343875
