For the second time today I do feel old. I issued on my Debian machine. The list of changes notified me that
gsettings-desktop-schemas (50.1-1) experimental; urgency=medium
Since GNOME 50, X11-style middle-click paste (pasting the primary selection, usually activated by a middle mouse button click) is disabled by default, because it was often done accidentally by users who did
not expect it.The recommended way to copy/paste text is via the clipboard, usually Ctrl+C, Ctrl+V or Ctrl+Insert, Shift+Insert.
If recommended packages are installed during upgrade, a user session migration script will keep middle-click paste enabled for existing user accounts. If the upgrade was done while logged in, it will be necessary to log out and back in to make this take effect.
Middle-click paste can be configured via the “Tweaks” utility from the gnome-tweaks package (Mouse & Touchpad → Mouse → Middle Click Paste) or by using the gsettings command from the libglib2.0-bin package, for example:
gsettings set org.gnome.desktop.interface gtk-enable-primary-paste true
Middle-click pasting was a staple of Unix. I used it since well…. before Gnome existed. Well, “oh the times they are ‘achangin“
And yes, I do have stable, testing, unstable AND experimental in my sources. Here’s how to live happily and easily with it.
