Re: Ctrl-C and Ctrl-V stopped working under KDE Plasma

FOOBAR is a sanity test ;-)
So there's a chromium clipboard handler which holds both main "clipboards" (PRIMARY is the selection/3rd button cnp, CLIPBOARD is ctrl+c/p) and something weird which looks very similar to the root window, but likely is not (compare "xwininfo -root") which holds the wacko SECONDARY buffer where nobody knows what it's actually good for.
You could kill all chromium PIDs and see what changes (though I assume while the owners change, the behavior won't restore)

Then it gets interesting: try killing the SECONDARY buffer owner:

xkill -id 10485935

ENSURE FIRST that
a) this is NOT the root window
b) you're prepared for an immediate session loss, because we don't know what this window belongs to

See which process dies as consequence and oc. whether the clipboard behavior is restored.

Re: Ctrl-C and Ctrl-V stopped working under KDE Plasma

Refreshing. I have the same problem after recent update. CTRL+C/V and SHIFT+INS does not work in Opera, Leafpad but CTRL+V works in Libre. If i copy something from Libre and paste it to Opera, Leafpad, nothing happens.

Re: Ctrl-C and Ctrl-V stopped working under KDE Plasma

And did you check the selection owner status and, in case, what that window belongs to?

Re: Ctrl-C and Ctrl-V stopped working under KDE Plasma

I am revisiting this after 6 months.

After multiple updates, until the initial problem has been reported, CTRL-V still does not work in any application (except for the virtualized OSes in VirtualBox). The only way to use the paste functionality is through SHIFT-INSERT.

Since I already invested a lot of time hacking this issue without arriving at a workable solution, my conclusion is that KDE simply does not work for me (one ThinkPad and one ThinkStation).
No, window ownership is not the central problem, or it is messed up to the level that I cannot even understand what is expected and what is buggy behavior.

At this point, I am concluding that this issue already consumed an unjustifiable amount of my time and I am abandoning KDE. Setting up a paste shortcut should not require this amount of hacking and I am not able to find any relevant community documentation that covers the issue.
