ATI Radeon 7500 TV-out?

Message

First I apologize if there has been several threads about this already but I can't find them if thats the case.

#1. How do I do to activate the TV-out on my Radeon 7500?
#2. Do I have to use the GATOS-drivers?
#3. Is it possible to have the TV-output as a separate screen and not a clone, if so, how?

To the rescue?

ati-gatos yeah or atitvout or use windoze
I have a 7500 M7 in my laptop. If you have a pci or agp version like the allinwonder radeon 7500 I'd try the ati-gatos drivers you might not have the same limitations.

atitvout works and I have used it - it only works in 800x600 mode and you CANNOT use the LCD and the TV simultaneously.

Get atitvout from here http://0pointer.de/lennart/projects/atitvout/

and below was taken from here http://www.nuclearelephant.com/papers/t30.html for its clarity

TV Out
It took me a long time to figure out how to get the TV-Out to work with my Radeon Mobility 7500, but it does in fact work. The first thing to do is install a tool called atitvout (you've probably already done this and pulled your hair out trying to make it work). Once the tool is installed, you'll need to reboot with the S-Video connected to the TV. I have not yet figured out a way to "reset" the video card so that it would be detected in real-time, but I'm sure there is a way (as Windows does it). Anyway, once you've rebooted, you can run "atitvout detect" to confirm that the TV is detected and connected to S/Video. Next comes the tricky part...

In order for atitvout to work, I had to create an X session using the vesa driver (instead of radeon). In order to do this, I had to create a copy of my XF86Config file (or xorg.conf if you're using Xorg) and change this line:

Driver "radeon"

to:
Driver "vesa"

You'll also need to set the resolution to 800x600 or lower for standard television sets. Save this new file as something like XF86Config.vesa. Now you have two options: you can either reboot and start X using this config, or you can simply create a dynamic X session from your normal all-purpose desktop. You can do this in much the same way as I previously discussed under Dynamic 3D X-Server Creation. Chances are, if you're wanting to get the TV to work, you want to watch a movie - so I've concocted this handy little script to automatically start up an X server and Mplayer's GUI in full screen mode:

#!/bin/bash

/usr/X11R6/bin/X :1 -xf86config xorg.conf.vesa -depth 24 -auth /var/gdm/:1.Xauth vt8 &
DISPLAY=:1.0
export DISPLAY
sleep 5
atitvout ntsc
atitvout -f t
gmplayer -vo sdl -fs
atitvout -f lc
DISPLAY=:0.0
export DISPLAY

As usual, when you're finished you can press CTL-ALT-Backspace to end the session or CTL-ALT-F7 to switch to your normal desktop.

NOTE: I haven't found a way to allow the TV and LCD to simultaneously function. It's presently either-or. GMPlayer also requires the use of a different video output device than the standard X11. This can be SDL, if you have SDL support (hence, -vo sdl) or vesa if you don't (-vo vesa).

Hi

I've used atitvout also to control the tvout. I really don't know how this is different from Dolemites way but you don't have to restart the machine to make it work (at least on my computer...). I'm using Radeon 64 DDR which is quite same as 7500 (infact I think it is 7200). By running in console with proper mode (800x600@ 60Hz?) you can do the following to switch tvon out on or off. And then start X.

to switch tvout on:

Code: Select all

atitvout -r auto
atitvout -r auto

and off:

Code: Select all

atitvout off
atitvout detect

btw: with quite new kernel (2.6.7) and X (xorg 6.7) I haven't been able to control tvout from X. Screen alway gets messed. So I have controllet it from console with those atitvout commands.

hi,

you don't have to reboot, what you can do is go into suspend mode and after waking up, you can use tvout, no reboot required, but it's not a final solution, because windows don't need even this.

Thx for you're solution with the vesa ....

thats good to know- isnt a special suspend partition required to use suspend?- acpi or apm? I never setup suspend because of that.

Gatos has support for TV out. Which versin of X are you using?
If you have Xfree 4.3 or XOrg 6.8 you do not have a problem. I think, but I am not 100% sure, Gatos does not work for Xorg 6.8.1. Check the website

Moreover, Gatos is part of Xorg in version 6.8.2

Finally, you can use directfb and this is what I am using. This is not because Gatos doesn't work, but because with Gatos I had to set the resolution to 800x600 for the TV, but for the monitor is 1024x768. This means that a 800x600 resolution did not fit in the monitor. Up to now I was not able to find a solution for this.

I just did a small improvement of Dolemite's script (thanks! thanks!) so now it kills the X server right after gmplayer exits.

Code: Select all

#!/bin/bash
 
/usr/X11R6/bin/X :1 -xf86config xorg.conf.vesa -depth 24 -auth /var/gdm/:1.Xauth vt8 &
xpid=$!
DISPLAY=:1.0
export DISPLAY
sleep 5
atitvout ntsc
atitvout -f t
gmplayer -vo sdl -fs
atitvout -f lc
kill $xpid

Does this mean I just have to emerge ati-gatos and it works in conjunction with xorg-x11?

Good news!

Which video card are you using? If it's a dual output card (1 VGA/DVI + 1 TV), can't the TV resolution be whatever you want?

How is the performance with directfb? Are you able to watch video smoothly?

I am running an AIW 7500 and it would certainly be nice to finally be able to use the TV out under Linux.
