I'm not sure the OS can detect the video drivers.
you do a lspci and it shows up, but the OS doesn't know what it is.
you attempt to force various driver packages on it from the saucy repository, the nvidia-331 and others, but all you get is a message saying xserver can't start.
you look at log and you get an error that it can't detect screens i guess because GLX won't start.
is anyone running linux on a 4800 with this k2100m card? getting native graphics without going compatible.
Maybe this is necrobump, but have your success with linux mint and your K2100 ?
