[LightDM] display mode changing when lightdm launches?

[Mickey Lyle]

Thanks Robert! I figured out that it's X that is doing the mode change,
it's ignoring my KMS mode, preferring the default mode that it polls from
the monitor instead of the one set in KMS. If I could fumble through
getting an xorg.conf to work I could probably fix my problem, but given how
awful xorg is, I'm not sure it's worth it. Thanks again and sorry for the
noise on your list!
