I didn't have this problem before I upgraded to 18.04, though. In fact, I've never had this problem with any release since I started using Ubuntu with 8.04 years ago. It was literally right after I upgraded and restarted my machine that the problem appeared--it didn't appear before the restart that was required to finish the upgrade. So I'd assume it's something within the updgrade.
I couldn't tell you about the repos being activated, because I frankly don't know what those are. I don't know much of the under-the-hood of Ubuntu yet. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1758306 Title: Cannot switch mouse primary button to Right (left-handed) in Settings To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1758306/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
