Description Joakim Sindholt 2009-12-01 17:29:19 UTC
When X starts it will incorrectly report that a monitor is connected through my Mobility Radeon X1400 (M54/RV515) S-Video port, even though no cable is in the port. This then causes GDM at least, to select the best common mode between the LVDS and S-Video, which happens to be 1024x768, thus showing a stretched and blurry picture on the LVDS.

This happened for the first time on the Fedora 12 live-cd. Approximately 1 or 2 weeks prior to the F12 release I had used Rawhide with no such bug.

Reproducibility:
Every time

Steps to reproduce:
Start the F12 live-cd or any F12 installation on the appropriate card.

I have attached the VBIOS for my card on recommendation of airlied. Hope this helps and thank you in advance.

The output of the S-Video port is garbage. The VGA port also outputs garbage, but seemingly works at random.
This bug still persists on the Fedora 13 BETA LiveDVD

tv-out load detection is very often unreliable.
