People doing the 30 days linux Challenge are having several problems because of Mint's old packages and technology. Why people still recommend it when there is Fedora and Opensuse with KDE and Gnome?
Because people suggest distros based on their preference, not what is best suited in a given situation.
On one hand Mint is limited to X11 for now and surprise surprise “dealing with multiple monitors is horrible on Linux”. On other hand they’re on NVIDIA. This is close to not be the case, but X11 was a hard requirement for decades
