All,

I configured Knoppmyth using a computer monitor(LCD) and I got everything working. It was set up to 1024x768.

Now I want to connect it to a TV, so I connected the SVIDEO out of my ATI Radeon 8500. It boots up and everything looks good until after the splash screen, then it goes black.

So I changed the default res to 800x600 in XF86Config, and it still does the same thing.

Any ideas how I can get TV-Out to work past the spash screen? What do I need to edit/change?

Your modelines? Your driver? ... Any of several other things?

However you'd be better off actually diagnosing the problem before you start flailing around changing things blindly. See the TroubleShooting pages on the wiki. Especially this one - http://www.knoppmythwiki.org/index.php?page=CheckingLogFiles Your X logfile is the first place to look. See what it's complaining about aside from missing font paths. After that, look for directions on setting up with an ATI video card.

My driver is the default XF86 RADEON driver.

Isn't there an OPTION that I can add to XF86Config-4 that does TV-OUT, using this driver?

I also tried installing knoppmyth with 'TV' from the get-go. TV out worked fine during the whole configuration, but after the first reboot, it goes to the black screen.

Because of their historically poor support for Linux drivers, ATI support for TV out is still a work in progress. It works for some people, and there are writeups here and on the wiki for setting it up. So far you haven't provided us with any logfile extracts however, or other useful information to indicate which if any of these directions you're trying to follow, what errors it's encountering, ...

Did you search?

Did you find this "blacklist" thread? http://mysettopbox.tv/phpBB2/viewtopic.php?t=6321

Did you find the thread it links to which describes some people's success? http://mysettopbox.tv/phpBB2/viewtopic.php?t=6309

Or this one that they were following? http://mysettopbox.tv/phpBB2/viewtopic.php?t=3279

HI,

Check for 60 htz vertical refresh in the XF86Config-4 file, I know my lcd will only work at 60. A pain cause I have to use an old crt to do the setup and edits first.

I installed the new ATI Linux drivers, and then I did the following from one of the threads:

"- Download the package from the ATI site
- Convert the RPM to a .deb and install it
apt-get update
apt-get install alien
alien fglrx-4.3.0-3.12.0.i386.rpm
dpkg --force-overwrite -i fglrx_4.3.0-4.12_i386.deb

this installs a program called fglrxconfig which will make an XF86Config-4 for you. "

I did all of this, but it did not install 'fglrxconfig' anywhere on my system.

I ordered a couple Nvidia cards with TV out just because I need to learn more about how Linux drivers work without getting frustrated.

I will build a second Myth box and try to get the ATI to work, but in the meantime, my wife just wants ONE that works with a TV!

I took a step back and approached the ATI TVOUT from the Linux support sites. I collected bits of data from various sources and came up with a working XFG86Config-4 file for ATI AIW 128. The ATI site's link is http://lerdorf.com/t42p_XF86Config-4

You may only need to add a few lines. I did install ATITVOUT found on GATOS, but I'm not certain if that pacthed anything. It did allow me to confirm if my card had CRT and TV Composite active. I had it hooked up to the SVideo and it worked, but ATITVOUT reported TV not active.

#for search: ATI all in wonder TVOUT wunder Xwindow

Hi,

Try dropping back to a console, ctl alt F2 should do it. Login as root, do killall gdm, then do startx and it should report any issues. If x starts clean, alt ctl backspace should kill it. gdm restarts your xserver and frontend. Fix anything needed to get x to run as desired.

You can also do this testing via ssh (easiest method) hopefully you will find some clues to get you going.

Mike

No problem will report if Knoppix OS thinks everything is good. Above config file has a few MUST HAVE entries for the screen to display correctly.

myth19kirt,

So this does this config file care which Radeon driver I have installed? The default generic (open source) drivers, or does this require the ATI Drivers?

I will give this a try tonight.

Thanks!

Note that the above XF86Config-4 file has a DRIVER "vesa" instead of "ATI". My CPU is doing the work as I have no HW acceleration.

I tried three ATI cards. The AIW Rage2+ and Radeon 7200 were PCI and did not have sufficent bandwidth to playback except at the lowest bit rate. I thought of changing the PREBUFFER settings, but have yet to try. My ATI128 AIW is AGP4 and has a good playback.

I have redone my Mythbox using AUTOINSTALL without using TV, and then overwrote the default XF86Config-4 with the above and that alone worked; giving me TV out. I did not need to install any drivers. My ATI128 AIW is AGP4 and has a good playback, except for HIGH QUALITY videos with a lot of movement. "Price is Right" occasionally has a slight audio stuter, and scan lines appear where high-motion occurs. I currently use a variable bit rate of 2200 - 4200.

New ATI cards maybe able to use ATI's linux drivers and gain some hardware acceleration. I tried the GATOS ATI Theater drivers, but was not certain what I was doing. I stopped experimenting, but if someone gets the ATI Theater acceleration working I may pick it up again.
