The driver doesn't seem to detect your internal panel (LVDS), it's
surprising that upgrading Xserver and keeping intel driver 2.9.1 broke
this. You should try with kernel modesetting enabled if not already done.

Then you could try forcing the enabling of LVDS (or LVDS1 if KMS is
enabled) by using
  Option "Enable" "true"
and then add custom modelines if needed, see
