xorg problem: no color at TV AFTER start
 

Hi,

Really awkward thing: when I start KDE /more specifically -- xorg/ and then connect computer to my TV /s-video -- euro-scart/ I can see desktop screen with no problem, however it is black&white. If now I restart just xorg /not even the system/ without disconnecting TV, the picture gets colors even at the KDM login screen.

How to get the colors no matter when I connected computer to TV?

thanks in advance
