While fixing a problem with a Wayland app I noticed that the programm got a notification from a Wayland fd whenever I selected some text in any other window (not belonging to the app) and was able to read the contents of the selection.
As I’m not a fan of sharing data without explicit actions (so Ctrl+C, Ctrl+V), is there a way to disable this behaviour of Wayland?
OS info: Fedora 43 KDE
I thought this was an old feature of Linux (maybe Unix?). Highlighted text gets copied to the buffer, which is useful when you’re on the command line (because Ctrl+C ends the current process).
I don’t know how you’d change this, but maybe that can give you some clues on what to do.
It’s been a hot minute, but wasn’t what you’re referring to done by a third-party app? The original consoles had no real concept of a mouse by default, let alone copy/paste from highlighted text. Any highlighting inside an app (e.g. vi/m) was buffered by the app and not the OS?
It was implemented as part of the X11 standard, so the concrete program would’ve been X.org…
I thought text selection was handled via keyboard. Also been a hot minute since I first learned about this, and not using that buffer has not exactly been a common discussion point, since being able to reuse text is typically a desirable trait!
