THANK YOU ALL for your replies. I’ll do a clean install and made a backup of my files (was not difficult bc most stuff I have in the cloud). I’m moving indeed from Mint to OpenSuse Tumbleweed. I don’t know exactely why, but it seems to me an interesting thing to do. Still figuring out what distro fits me best.
I’m still in the fase of exploration. When using Windows, you just have 1 choice. I just want to discover what suits me best. So nothing against Linux Mint. It’s great, but maybe OpenSuse is better for me? I don’t know.
