Recently I found the auto-copy on selection feature of gnome-terminal really annoying. However, I tried to look for a way to disable it. As it turns out, there's few documentation for that. I was wondering if there's a way to disable this feature?
That's not gnome-terminal doing that, it's X. And there's no way to disable it since "copying" in modern environments is just copying the PRIMARY selection to the CLIPBOARD selection therefore disabling it would prevent any copying at all. Just learn to not hit the middle mouse button.
