Hey Everyone,

I've been looking around here a bit and trying to find a solution with no success so far, so I thought I'd open it up to greater minds.

I've just installed 9.10 on a machine with a Radeon 9200. I'm using the open source ati driver, and I'm trying to set up my monitor to be a Philips 30PW9100D/37B, which supports 480P and 1080i. 480P is enabled in the set by default, and in the monitor settings dialouge I can choose 1920x540, which I'm assuming is the 1080i as 540 should be the pre-interlaced number of pixels. However, if I switch to this setting the screen acts as though it is not getting an input, and displays nothing. I've managed to pull the EDID settings off of a windows box if that's helpful for everyone, so here they are:

Here's my xorg.conf, some things are commented out because either because there was no effect, or they interfered with me using an lcd monitor in the meantime.

EndSectionI've tried setting the modelines in my xorg.conf, but it hasn't had any effect as far as I can tell. If anyone's got any ideas, I'd love to hear them!
