I'd be surprised if this is NOT a duplicate but I've searched long and hard. I'm on linux - fedora 24, There are so many different versions of kde things in my yum list installed I don't even know where to start. SOMEHOW I managed to create a very large number of sticky notes - some unintended use of keyboard or mouse or combination. 1. How can I find out how many there are? 2. How can I delete them all at once, not one at a time? 3. How can I kill/disable/remove/eliminate notes from my desktop? 4. I suspect that whatever created the notes also caused my copy/paste to stop working. How can I reset whatever it does that makes copy/paste work?
Please keep in mind that this is not a user support forum. What's happening is that when you middle-click on the desktop, it pastes the clipboard contents into a new sticky note. See http://www.ocsmag.com/2017/06/17/plasma-secrets-tips-and-tricks-for-the-kde-desktop/ To disable this behavior, right-click on the desktop, click on "Configure Desktop", then go to "Mouse Actions" and then remove the action for "Middle-Button" by clicking on the button with a minus sign on it. You might try asking in a Fedora-specific forum (or even just a general KDE forum) regarding answers to your other questions.
You don't view it as a bug that the UI doesn't seem to give me any way to get rid of all these notes? Or find out how many there are? I restarted my computer and every screen is still full of sticky notes. I don't even know what I can uninstall to get rid of them.
mouse actions says middle click paste -- but I want that. Normally it doesn't paste into a sticky note. Why it did so this time I don't understand.
I'm actually not sure either. It's quite likely that there's some sort of bug there that caused the unintentional creation of so many notes, but if you can't reliably reproduce the issue, we have no way of knowing where it is. Please let us know if you manage to find some concrete steps to reproduce. As for removing them all, you can right-click on them and click remove. It'll have to be one-by-one, I'm afraid, because each note is actually its own separate widget.
Here's another indication of a bug: From application launcher, utilities, I click on popup notes (knotes) This gives me a taskbar icon. Right click on that shows delete selected notes. When I click on that I get an empty list, even though all my desktops were already filled with empty notes before I did any of this. I can create notes and get them to show up in that list. And when I quit notes, the new ones disappear but not the old ones.
KNotes is a standalone app that manages one or more notes; the sticky notes that appear on the desktop are individual Plasma widgets.
Can you at least tell me where these notes are stored? Why is this so difficult to figure out?
~/.local/share/plasma_notes/
Wow, 211 of them. Can I effectively delete them all by just deleting all of these files?
Yes, I think so. We'll track the issue of not being able to easily remove them all at once with Bug 397240. *** This bug has been marked as a duplicate of bug 397240 ***
>mouse actions says middle click paste -- but I want that. This setting only controls middle clicking on the desktop, not general behaviour. From what you described, you don't want that.
