I suppose in this case you'd have to hope that the SDVO init code at POST time set up the device correctly, so that if you called SDVO_CMD_GET_LVDS_PANEL_INFORMATION it'd tell you the truth. But that assumes that the SDVO init code does that, and it might not, I don't actually know; Intel doesn't release the docs for that publicly (or even under NDA unless you're an OEM). That or we'd need to add a way of passing in a VBT from the kernel command line, like ACPI DSDT override does. - ajax --=-Tb904eSbyqO3lrH3kQ/S Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iEYEABECAAYFAk6e5pYACgkQW4otUKDs0NOVtQCeKp9u1UixF2218o1eaHweIwNd QpAAnjW3TmFwphrRwVx18EsrnQHZbhYl =OT5E -----END PGP SIGNATURE----- --=-Tb904eSbyqO3lrH3kQ/S-- --===============1357597897== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx --===============1357597897==--
