I am running a geforce 6200 card with ubunt 12.04 with nvidia drivers installed. I am a nubie to ubuntu but love it. I would like to find out how to set up the component dongle to output to my Samsung flat tv. It does display on the tv but there is no color. All cables are set up correctly. If i run sudo nvidia-xconfig it backs up the xconfig file and will not let me adjust anything. Cannot change anything in the nvidia control panel, the apply button is grayed out. please help, i would really like to watch movies and surf the net on my tv.
