Hi, > So I upgraded to F23 just around Alpha or Beta can’t remember and I’ve experienced some odd mouse / copy paste behaviour. I haven’t yet filed a bug but now I’m wondering… How do I know if I’m using Wayland? I’ve never specifically configured it so anything I’m experiencing in a normal GNOME 3 session is either ‘normal’ but I don’t like it, configurable change that has a different default or some weird bug… I’d like to know if I’m somehow not using X anymore, and that’s the problem. It's unlikely that you're using wayland in Fedora 23 since it's not the default. You can check if you're on wayland by running $ ls -l $XDG_RUNTIME_DIR/wayland-0 if it returns a socket you're probably using wayland. -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
