after a lot of messing around a finally got the TvOut working on my laptop which has a Ati FireGl 9000 video card. Here is how:
lspci says this about my video card:
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon R250 Lf [FireGL 9000] (rev 01)
First I downloaded&installed the ati-driver. The version I used was "ATI Proprietary Linux x86 Driver 8.26.18" which appears to be the last driver ever to support this card. Download from https://support.ati.com/ics/support/...ge&folderID=27
Install as laid out in the Installer instruction (simply execute the downloaded file as root)
Then you can use 'aticonfig' to update your xorg.conf file.
aticonfig without options will show you how to use it.
aticonfig --initial=dual-head --tvf=PAL-B --tvs=VIDEO --hsync2=50 --vrefresh2=50 --ovon=1 -v
will create a dual-head config with my lcd "left" and a second screen to the "right". (I found this on the gentoo-wiki: http://gentoo-wiki.com/HOWTO_TV-Out
But what I was looking for was this:
/opt/ati/bin/aticonfig --initial --tvf=PAL-B --tvs=VIDEO --hsync2=50 --vrefresh2=50 --dtop=clone --ovon=1 -v
This will create a "clone" of your lcd screen on your TV.
Make sure to re-start your X-server to activate the settings (f.i. using Ctrl-Alt-Backspace).
Your old xorg.conf from by backuped up as xorg.conf.original.1 but making your own backup beforehand won hurt.
Good luck, Ronald
