If, like me, you happen to be using an NVidia based graphics adapter with TV-Out, you might find useful the following instructions to configure it, adding a KDE service menu to watch your movies on the TV with a single click.

Three steps are necessary:

1. Configure your X server, creating a TV dedicated layout. We’ll later start X using this setup.
2. Create a script to start X, running xine with the file we want.
3. Create a .desktop file which inokes this script for the MIME types video/*.

1. First we must have NVidia’s driver installed and running. This has already been discused elsewhere, so there is no need to elaborate. Once it is done (I recommend applying NVidia’s patches, which are posted on the forums), append the following to your /etc/X11/xorg.conf file:

1. #### Configuración para la salida de TV de NVidia <nonick AT 8027 DOT org>
2. #
3. # ATENCIÓN: aquí se hace referencia a las secciones "Mouse[2]" y "Keyboard[0]"
4. # Deberás sustituir estos identificadores por los tuyos.
5. #
6.  
7. Section "Monitor"
8. HorizSync 30-50
9. VertRefresh 60
10. Identifier "tv"
11. EndSection
12.  
13. Section "Screen"
14. Identifier "Screen_tv"
15. Device "Card_tv"
16. Monitor "tv"
17. DefaultDepth 24
18. EndSection
19.  
20. Section "Device"
21. Identifier "Card_tv"
22. Driver "nvidia"
23. BusID "1:0:0" # May differ (not needed unless you have two or more cards)
24. Option "TVOutFormat" "COMPOSITE" # or "SVIDEO" ?
25. Option "TVStandard" "PAL-B"
26. Option "ConnectedMonitor" "TV"
27. EndSection
28.  
29. Section "ServerLayout"
30. Identifier "tv"
31. Screen 0 "Screen_tv" 0 0
32. InputDevice "Mouse[2]" "CorePointer"
33. InputDevice "Keyboard[0]" "CoreKeyboard"
34. EndSection
35. Download this code: xorg.tvout.conf

2. Now you need the script to start the X server using the new tv layout. You can use the following if you like it; just save it somewhere and set it executable with chmod +x /path/to/your/file/tvout.sh:

1. #!/bin/bash
2. #
3. # v0.1 [ Thu May 19 09:23:04 CET 2005 <nonick AT 8027 DOT org> ]
4. # v0.2 [ Fri Feb 24 03:52:39 CET 2006 <nonick AT 8027 DOT org> ]
5. # v0.3 [ Mon Jul 10 12:02:50 CEST 2006 <nonick AT 8027 DOT org> ]
6.  
7. xineexec="/usr/bin/xine"
8. fileexec="/usr/bin/file"
9. wmanager="/usr/X11R6/bin/twm"
10. tvlayout="tv"
11.  
12. if [ ! -z "$1" ]
13. then
14. run="$xineexec -f -g"
15. arg=$1
16. # Se trata de una imagen ISO?
17. if expr match "$arg" '.*\(\.iso\)'
18. then
19. # Es una imagen válida? Sólo lo comprobamos si existe $fileexec
20. if [ -x "$fileexec" ] && file=$(file --brief "$arg") && \
21. ! expr match "$file" '\(ISO 9660\)'
22. then
23. kdialog --error "'$arg' no es una imagen ISO válida.\n$fileexec dijo: $file"
24. exit 1
25. fi
26. msg="¿Quieres ver la imagen ISO '$arg' en la TV mediante xine?"
27. arg="dvd://$arg"
28. # Es un fichero normal:
29. else
30. msg="¿Quieres ver '$arg' en la TV mediante xine?"
31. fi
32. else
33. run=$wmanager
34. arg=""
35. msg="¿Quieres activar la salida de televisión?"
36. fi
37.  
38. kdialog --warningyesno "$msg"
39.  
40. if (( $? == 0 ))
41. then
42. # Comprobamos que se puede ver
43. if [ ! -z "$arg" ] && [ -d "$arg" ] && [ ! -f "$arg" ] && [ -z "${arg#dvd:}" ]
44. then
45. kdialog --error "'$arg' no es un directorio o fichero válido."
46. exit 1
47. fi
48.  
49. exec /usr/X11R6/bin/xinit $run "$arg" -- /usr/X11R6/bin/X :9 -layout $tvlayout
50. fi
51. Download this code: tvout.sh

3. Finally, we add the konqueror context menu entry which will show when clicking thr right mouse button over a video file. Save the following file in .kde/share/apps/konqueror/servicemenus, just changing the path to your script:

1. #
2. # View file via TV out
3. #
4. # v0.1 [ Fri Feb 24 09:26:15 CET 2006 <nonick AT 8027 DOT org> ]
5. # v0.2 [ Mon Jul 10 11:42:50 CEST 2006 <nonick AT 8027 DOT org> ]
6.  
7. [Desktop Entry]
8. Encoding=UTF-8
9. ServiceTypes=video/*,application/x-iso
10. TryExec=tvout.sh
11. Icon=tv
12. Actions=ViewOnTV
13.  
14. [Desktop Action ViewOnTV]
15. Name=View on TV
16. Name[fr]=Voir à la télé
17. Name[es]=Ver por la TV
18. Icon=tv
19. Exec=tvout.sh "%U"
20. Download this code: file_tvout.desktop

4. Have fun!
