Personally I haven’t. While Linux is imperfect, choosing the right distro makes the rest of the experience straightforward. And with it’s whole complexity, I find Linux more user friendly than Windows. Even driver issues, broken shadow file ownership and KDE specifics only made me more confident about my choice to use Linux after I solved everything.
My Thinkpad X260 TrackPoint and mouse buttons under the spacebar still don’t work. I have lost my mind trying to figure it out and gave up. I don’t use the laptop that often.
I’ve had that Laptop and ran Arch (and other distros) on it with those working no issue. I’ve since passed it to a friend who also uses it with Debian and hasn’t complained about issues. Are you certain this is a Software issue? Are the TrackPoint and buttons actually plugged in? Do they show up?
