Thank you for your answer !

I was looking at pop os, and apparently KDE can be installed the way you suggested, however that might create some instabilities, that’s why I slightly prefer distributions that have KDE by default.

I guess i’ll stick to Manjaro then. It’s probably not perfect, but I like it.

Thanks for the advice on the partition. If i’m correct, I won’t have to modify anything besides sda4 and sdb3, so I guess I should be fine

Oh, ok, I did not have any issue so far so that surprised me, but I guess I was just lucky

I’m out of the loop, why is Manjaro considered a “bad distro” ?

I have used it for quite some time now, and I enjoy it, i find it fairly simple, fast and pretty.

Is there something I’m missing ?
