Fedora ships with support for several desktop environments, which are easily installable, such as XFCE, LXDE, Sugar, and several others (including, of course, KDE as well!). Fedora's default is Gnome 3, but that doesn't mean it's your only choice. The other options might be more suitable for a low resolution display.

Through 3rd-party packages, other environments might also be available, such as Cinnamon and MATE.
