Linux on new computers is always dicey. Or it has been for me.
Right now I have a Windows 8-running (aka Secure Boot-equipped) HP Pavilion g6-2210us, and its AMD video chip is not playing nicely with 3D-accelerated video in Linux.
So GNOME 3 is unusable, Ubuntu's Unity is marginal.
But Xfce, in all it's 2D glory, looks perfect.
