View Full Version : [mythbuntu] Tv-out only in open source ati driver?
August 21st, 2009, 06:39 PM
I have a mythtv box that's connected to a PAL tv via S-video. It has no other monitor. I was wondering if someone has any idea if it is possible to get this to work with the open-source driver.
I know about the:
xrandr --addmode S-video 800x600
xrandr --output S-video --mode 800x600 --rate 50
trick, but it only seems to work if there already is a monitor connected.
Any help would be appreciated.

It works on mine (Radeon X300) although I had to set the TV standard to NTSC to get a picture. I also had to turn off DRI otherwise Mythfrontend displayed only blank rectangles.
I'll be installing a Geforce 7300 as soon as the postman turns up with it.
My current xorg.conf
DisplaySize 272 153 # or 203 143 for 4:3
Option "PreferredMode" "800x600"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
Identifier "Configured Video Device"
Option "DRI" "off"
Option "ForceTVOut" "on"
Option "TVStandard" "ntsc"
Option "monitor-S-video" "TV-monitor"

Well, it's still not working properly, but that actually helped a lot since now it actually displays something on the screen, even if it's just garble. The card is a RV200.

That sounds like the picture I got when I set the output to PAL.

I got it to work, even in PAL mode. Your xorg.conf actually worked, I had just forgotten to "--purge remove" the fglrx driver.
I will however as well find a nvidia card, because without dri it is quite slow.
Thank you for the help non the less.
