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

[Fernando Gomes]

Hi, I have a Ubuntu 8.04 with MythTV installed with a ATI 9250 graphics
card. After reading some posts I managed to activate the TV-Out using the
following commands:

xrandr --addmode S-video 800x600
xrandr --output S-video --mode 800x600
xrandr --output S-video --set tv_standard pal
xrandr --output S-video --off
xrandr --output S-video --mode 800x600
xvattr -a XV_CRTC -v 1

This is working perfectly with my 42" plasma TV, the only problem I have now
is that it doesn't work if I start the PC without the VGA monitor connected
(only works well with the TV Out if the VGA monitor is also connected to the
VGA connector). Can anyone suggest me some tip to solve this limitation? I
want to use this PC with no VGA monitor, only a TV connected to it.

Thanks!

Fernando
