--- Comment #216 from pitlochry <pitloc...@gmx.net> --- You have to delete at least ~/.config/plasma-org.kde.plasma.desktop-appletsrc (perhaps also ~/.config/plasmashellrc and ~/.local/share/kscreen/). [Because of another bug I deleted all ~/.cache ~/.config and ~/.local] Then you have to reconfigure the appearance of plasma. Then you will see the bug has improved: The taskbar and the wallpaper stays when plugging in the hdmi cable. Alas, unified output is bugged. When clicking on unified output+apply, the output is not unified (I understand unify as "mirror output"). Only the resolution is set to equal. There are now 2 independent screens side-by-side (as before the unification), but the image in Settings->Display is now unified to one screen (before there were two screens shown). So, either this image is wrong or unified output is bugged. One can unify (i.e. mirror) the output e.g. by enabling 2 virtual workspaces, then unify output, then reduce to 1 virtual workspace. Then it is really unified (mirrored), although Settings->Display says that it is NOT unified (it offers the option to unify and not to break the outputs). Another error (but I have to check on another screen, because this seems odd): On each edge are missing approx. 50 pixels. Another error: When you unplug the hdmi cable it shows the old unified resolution, although it has (thankfully) switched to the default resolution [no big deal, you have to reload the settings, then it shows the right resolution] -- You are receiving this mail because: You are watching all bug changes.
