hi,
diff below seems to let me use igfx on a thinkpad x1 carbon
3rd gen with a broadwell chipset.
% cat /dev/vgactl
type igfx
size 2560x1440x32 x8r8g8b8
tilt none
hwgc soft
hwaccel off
hwblank off
addr p 0xc0000000 v 0xffffff00c0000000 size 0x4000000
softscreen on
i tried using the hdmi port on the side but the tv did not
get a signal. i have been testing it lightly and there does
not seem to be much difference from vesa.
