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?
By default Mint ships 3 years old kernel and a lot of hardware don’t work with it. Mint allows installing newer kernel easily but one must know that is the case.
Mint only works on X11. This is fine to some, but to others it’s a showcase of X shortcomings right away
