If you're referring to openSUSE rather than Linux in general, I have had the opposite experience. I had been on Manjaro for the past couple of years and decided to switch to openSUSE Tumbleweed on a whim and everything for the most part has just worked out of the box with minimal troubleshooting (or just a lot less than I remember when I was originally configuring my Manjaro install). What all have you had problems with?
