loginctl info

I'm running KDE Plasma 5 on Arch Linux, and I have discovered that if I press Alt+Left or Alt+Right or Alt plus a function key (as if I were in a console VT session and attempting to switch to a different VT), logind thinks my session has become inactive.  However, pressing Ctrl+Alt+Left does not have this effect.  I have attached some relevant information from loginctl.

So you are saying that on Alt-Left the KDE session stays in the foreground but logind thinks you switched away from it?

logind doesn' handle Alt-Left, that's up to the DE. And Ctrl-Alt-Left is an X11 thing to handle.

What is KDE doing on Alt-Left?

Yes, the problem was that the KDE session stayed in the foreground but logind though I switched away from it.  I couldn't find any action assigned to Alt+Left in KDE's shortcut key configuration, so I assumed logind was somehow receiving it directly (which is of course ridiculous).  However, I cannot reproduce it anymore.  I recently had an NVIDIA driver update; maybe that driver was doing something stupid.

OK, will close then. Feel free to reopen if this returns and turns out to be a logind issue.
