| |
| − | The provided archive contains a source release which can be compiled and installed by {{cmdroot|make && make install}} within the extracted directory. The atitvout tool will then be installed to {{path|/usr/local/sbin/atitvout}}.

| − |
| |
| − | The tool uses the VESA Bios Extensions (VBE) which are initialized only once during power on. So if you want to use the TV-out, be sure to get the corresponding video device such as a tv connected before powering your ThinkPad. Under some circumstances the tool fails to communicate properly with the VBE Bios. By issuing {{cmduser|atitvout -f t}} you activate the SVideo output port. The command {{cmduser|atitvout -f l}} you change the graphics output back to the LCD.

| − |
| |
| − | The atitvout doesn't seem to work on higher resolutions. To send a Xserver to a connected video device, it is possible to start a second Xserver e.g. with {{cmduser|startx -- :1 -xf86config XF86Config-4_reduced-resolution}}. For resolutions up to 1024x768 the switching should work fine.

| |
| − | While this works very well for ordinary X applications, playing video files, say with mplayer or xine might result in wrong aspect ratio or otherwise distorted output.

| − |
| |
| − | Switch to a text console (preferably a non framebufferd one) and issue an {{cmduser|atitvout -f t}}. Then start {{cmduser| mplayer -vo svga}} and the filename and other options needed. After enjoying the show, switch back with {{cmduser|atitvout -f l}}.

| − |
| |
| − | If you have problems with weird colors when moving the mouse or pressing Alt, either switch to a terminal and back, or just disable hardware cursor in you X config.

This HOWTO should help you enable TV-Out support on your ATI Radeon or ATI Rage based ThinkPad.
Using Xrandr (preferred)
To use the TVout on Radeon 7500 type following:
$ xrandr --output S-video --set load_detection 1
$ xrandr --addmode S-video 800x600
$ xrandr --output S-video --mode 800x600
And set mode PAL or NTSC with:
$ xrandr --output S-video --set tv_standard ntsc
If you want to use XVideo overlay on TV, try following command:
$ xvattr -a XV_CRTC -v 1
ThinkPads/Other laptops this has been successfully tested on
- A30p
- T30
- Compaq Evo N800v
- T40 with Radeon 7500
- T41 with Radeon 9000
