ASUS M2A-VM HDMI issues

[gsmd]

I'm running Ubuntu 8.04 meant intended for use as a mythtv box with tv connected via hdmi as the only display.
I've installed fxglr from ubuntu repos and it would work on monitor connected to VGA/DVI but not over hdmi.
Here's my xorg config that would bring video to tv if only ati driver is disabled. Otherwise I get a black screen. Has anyone who faced such an issue was able to sort it out?
TIA.

I would try removing the "Modes "1920x1080" and "VertRefresh 60.0 - 60.0 " lines from your config file, see if the ati driver can auto detect.

If your computer is reasonably powerful, you could always run the open source radeonhd driver with software video for the time being until you get the fglrx issues sorted out.

Hi. Removing those doesn't help. Thanks on suggesting radeonhd, i'll check this out tonight. Not sure whether it would a)perform good on fullhd b)will get sound over hdmi.

Well, radeonhd finally brought a fullhd picture to my tv, yet still no luck with sound. unmuting the hdmi sound output makes mythtv slo-o-ow. anyways, sick of asus, switching to gigabyte's 780g mobo.
