If you are having trouble getting TV-Out functionality on a Radeon graphics card below Radeon 9500, the following instructions may help you. This method patches the open Xorg open source drivers with a tv-out patch from the GATOS project. These instructions have only been tested with [[Ubuntu]] Edgy.

Try these instructions if installing the proprietary drivers gives you a
"high gamma" or "washed out" looking screen whenever the TV jack on card
is in use at boot-time, or if your card is a Radeon with TV-Out that is not supported at all by the proprietary ATI drivers (fglrx).

==Pre-Installation==
===Download Prerequisites===
First, install driver and other needed packages.
Copy/enter the following into the terminal.

sudo apt-get install build-essential libdrm-dev mesa-common-dev \
x11proto-render-dev x11proto-core-dev x11proto-fonts-dev x11proto-gl-dev \
x11proto-randr-dev x11proto-video-dev x11proto-xext-dev \
x11proto-xf86dri-dev x11proto-xf86misc-dev x11proto-xinerama-dev \
xserver-xorg-dev pkg-config

===Patching===
Second, use wget in terminal to download the driver and patch

mkdir ~/ati; cd ~/ati
wget http://megahurts.dk/rune/stuff/xorg7.1-6.6.3-tv_output.patch.gz
wget http://xorg.freedesktop.org/releases/individual/driver/xf86-video-ati-6.6.3.tar.bz2
*Note the above command is very wide, make sure you copy it all.

Next, patch the driver

tar xjvf xf86-video-ati-6.6.3.tar.bz2
gunzip -c xorg7.1-6.6.3-tv_output.patch.gz | patch -p1 -d xf86-video-ati-6.6.3

==Installation==
===Building===
Next, configure, build and install the driver

cd xf86-video-ati-6.6.3
export XORG_PREFIX="/usr"
export XORG_CONFIG="--prefix=$XORG_PREFIX --sysconfdir=/etc --localstatedir=/var"
./configure $XORG_CONFIG --with-xorg-module-dir=$XORG_PREFIX/lib/xorg/modules
make
sudo make install

*Note, using "sudo" will cause the terminal to ask for your password.

===Configuration===
Lastly, tweak xorg.conf by entering

sudo gedit /etc/X11/xorg.conf

and editing it with the following changes, note the specified lines:

Section "Device"
Identifier "<YOUR CARD NAME HERE>"
Driver "ati" #<---------Important line here
BusID "PCI:1:0:0"
Option "TVOutput" "NTSC" #<---------Important line here
EndSection

Section "Monitor"
Identifier "SyncMaster"
HorizSync 30 - 50 #<---------Important line here
VertRefresh 60 - 60 #<---------Important line here
Option "DPMS"
EndSection

Section "Screen"
Identifier "Default Screen"
Device "<YOUR CARD NAME HERE>"
Monitor "SyncMaster"
DefaultDepth 24 #<---------Important line here
SubSection "Display" #<---------Important line here
Depth 24 #<---------Important line here
Modes "800x600" #<---------Important line here
EndSubSection #<---------Important line here
EndSection

After this point, check for any typos, and save the file.

Then press CTRL+ALT+Backspace to restart X. If all went well, you should come back up to the login screen and your TV-out should be working fine. If its not up at this point, but you do come back up to a login screen, try rebooting with the tv cable plugged in.

==Utilities==

There is a utility called tvo_set which allows you to tweak the tv out options. It requires more headers:

sudo apt-get install libxv-dev

Now head back into the source directory:

cd ~/ati/xf86-video-ati-6.6.3/src/tvo_set/

xmkmf
make
sudo make install

The readme for tvo_set can be found in:

~/ati/xf86-video-ati-6.6.3/src/README.tvout
