Thanks for the reply. I did as you said - boot with the TV turned on. Below this post you can find the relevant lines from the Xorg log file.
I get now a screen on my TV, which is a clone from the LCD.
This is something ofcourse, but there are still two things bothering me:
- there is a black bar on the bottom of the tv, making me think that the sync values might not be optimal.
- the virtual size is 1280x1024, with a viewport of 1024x768, annoying for watching video.
With the second thing I have been fighting now for some time, but I was unable to figure it out. In the end I messed up my xorg.conf, after which I reinstalled the driver.
The first seems even more complicated to me. Since my tv did not provide EDID information (it's an old one), the driver might have guessed slightly wrong values. I have no idea how to fix this. I'm very grateful for any help given on the subject.
