Well, I think I’ve actually messed with libraries some times when installing or trying to some programs x’d. Yeah, regular Mint was surely a better choice, but well, now that I’m on LMDE I don’t find a reason to switch to Mint. I prefer directly going dual-boot with a distro that solves the concrete issues I’m having, since in general LMDE is totally ok but has these specific “issues” in my personal case. Thanks!
