I have an Antergos system all up to date with KDE desktop.
I assume it’s Plasma 5, though there is no obvious way to discover the version of KDE through KDE itself, which seems like an oversight!
Anyway, I would like Alt-tab task switching to give me something useful as a visual indicator of what I am switching to.
I have found my way to Settings->Window Management->Task Switcher
But none of the ‘Visualization’ options therein seem to work. Nothing on my screen changes when I am Alt-tab-ing.
Until recently, only ‘Breeze’ worked. Now even that one does not.
I have kdeplasma-addons installed. Even uninstalled & reinstalled.
Any clue how to get this working?
Possible hint to the problem:
If I run
kcmshell5 kwintabbox in an xterm, I get a bunch of outputs: (7 times to be precise)
kf5.kcoreaddons.desktopparser: Could not locate service type file kservicetypes5/kwin-windowswitcher.desktop, tried ("/home/peter/.local/share", "/usr/share", "/usr/local/share")
