The server doesn't have any built in intel driver.  You should figure
out what version you have, and update if it isn't 2.1.1.

I would guess that your monitor might not be getting attached to the
output you want.  Option "Monitor-TMDS" "Monitor_TFT-L" in the device
section would hook that up.  But it would be better to figure out why
autodetection isn't working -- update xserver (to get an EDID fix) and
xf86-video-intel and supply a log with Option "ModeDebug" "YES" to a
bugzilla report if the issue continues.
