radeon 9000 (rv250) tV-out troubles

[Charles Hibbits]

Thank you for the quick response.  I tried the values you suggested for the org.conf file.  They do not seem to change anything.  The xvattr worked great though.  I noticed something that may be of interest.  If I have a monitor attached GDM starts up fine (minus tv-out).  If I start up without the monitor attached, I get a message about Ubuntu is running in low-graphics mode it also modifies my xorg.conf to have all sorts of "failsafe" values in it.

Also, I fiddled with the xrandr command order a bit and found I can get away with fewer commands as such:
xrandr --addmode S-video 800x600
xrandr --output S-video --set tv_standard ntsc
xrandr --output S-video --mode 800x600

Monitor-less is also how I used this machine in xorg 7.2.

 understanding the instructions correctly so I apologize for another
 thread.  I have an Sapphire Radeon 9000 64MB with TV out. Everything was
 running fine with the patched opensource driver on Ubuntu Feisty (xorg 7.2
 I believe). Saturday I upgraded to Gutsy (xorg 7.3) and I lost the tv
 out.  At first the gnome X configuration tool set it to a VESA driver
 which produced black and white TV out.  When I use the XORG ATI driver
 the TV out goes away.

 again. Also My main usage of this computer is to run mythtv, but the
 video will not play on the TV, only the monitor.  I assume this has
 something to do with it not being treated as a primary display or something to
 that effect.  I assume there is something wrong with my xorg.conf, but
 I have not been able to find the right options. Here is my xorg.conf:

You can force the TV on with the following options (add to the device
section of your config):
Option "ForceTVOut" "true"
Option "TVStandard" "ntsc"

As for the overlay, it can only be sourced to one crtc at a time.  In
dualhead mode it follows the video window.  In clone mode you have to
explicitly tell it which crtc to source to.  Use an application like
xvattr to select the crtc for the overlay:
xvattr -a XV_CRTC -v 1

possible values:
-1 auto
0 crtc0
1 crtc1
