Hi Kevin,

   Sorry for late reply.
   Yup, "VBEModes" option can be used in xorg.conf to enable VBE mode.
   And for "vga=xxx" option, please see:
      https://en.wikipedia.org/wiki/VESA_BIOS_Extensions
   It can also be used for VBE setting I think.
   As far as I digged into the OpenChrome code, I found right now DP/HDMI port
is not supported, especially for VX900. So do think VBE can be used before they
are supported?

Thanks,
Frank
