[Intel-gfx] Does xf86-video-intel 2.11.0 support interlace? Lucid 2.6.33

[Xavier de Almeida]

Hello,

It's my first post in such mailing list. My issue is that I can't configure my old LCD supporting 1080i (interlace mode) with my Clarkdale i3 (h57) HD Graphics.

I see in the Xorg log such messages:
(II) intel(0): Not using mode "1920x1080i" (interlace mode not supported)

Therefore my 1st question is to know if interlace is supposed to work with these drivers?

Then I'd like to know what I am missing in my xorg.conf in order to be able to set this display mode (and also when the TV is not connected or powered on).

My issue is that the resolution "negotiated" is 1280x720_50.0 instead of 1920x1080i.

Thanks
XabiX
