[mythtv-users] Fwd: TV-Out configuration problem - doesn't work without VGA monitor connected

Thanks for your reply!

The link you sent me is only valid for the ATI proprietary drivers, but the
Radeon 9250 is not supported by the current proprietary drivers, so I'm
using the open source ones. Anyone in this list has a working configuration
for TV Out with a radeon board using the open source drivers? I want to be
able to use only a TV connected to the TV Out, without any monitor connected
to the VGA output.

Best regards

Fernando
