TV-Out on Intel 945GM

From openSUSE

The TV output on Intel 945GM is supported by the intel driver. However, sax2 in openSUSE 11.1 cannot configure this correctly. This Graphics chip has three output connectors but can only handle two outputs at a time, which means one of the outputs must be disabled.

• First, let sax2 configure the graphics. Create a backup of your working X configuration with the command:

cp /etc/X11/xorg.conf /etc/X11/xorg.conf.working

• In the Device section of /etc/X11/xorg.conf, there should be the following options:

Option "monitor-LVDS" "EXT"
Option "monitor-TV"   "EXT"

• Change these options to look like this:

Option "monitor-LVDS" "EXT1"
Option "monitor-TV"   "EXT2"

• Search for the Monitor section with the following line:

Identifier "EXT"

• Change the value of the identifier as follows:

Identifier "EXT1"

• To disable this output, add the following line to the same section:

Option         "Ignore" "true"

• The Monitor section for EXT1 should look similar to this:

Section "Monitor"
  HorizSync    30-81
  Identifier   "EXT1"
  ModelName    "SAMSUNG SYNCMASTER"
  Option       "PreferredMode" "768x576"
  Option       "Ignore" "true"
  VendorName   "SAM"
  VertRefresh  50-75
EndSection

• Create a new Monitor section:

Section "Monitor"
  Identifier   "EXT2"
  Option       "PreferredMode" "1024x768"
EndSection

• save the file and restart your X server.

Now, the basic configuration is done. You can check the success of the configuration with the command:

xrandr

To get colour on your TV, use the follwing commands:

xrandr --output TV --set TV_FORMAT PAL
xrandr --output TV --mode 1024x768
