> Is the lvds console display shifted if you don't connect any external monitor ?

So far I only got the LVDS to display anything by connecting the DP monitor, so
I don't really know.  I didn't try much there... I'll try some other magic
incantations/plug sequences tomorrow, maybe there's a sequence to get LVDS-only
with it actually showing something.

Starting X while the LVDS is off works fine, reenabling it.

Also, the "LVDS off" state after loading the module has the backlight off too,
maybe it's a bug in the brightness control and there is content but I just
don't see it...
