Yes, I use "nv" for normal use, when I have to use tv-out I change the driver. I have one "small" script to shut down gdm and change the xorg.conf and restart again. (with nv driver sometimes appears bad characters instead of letters and numbers, when I change resolution and come again it's ok, this is other reason to try to use the nvidia driver)
I'm, thinking to buy one ati x300 or similar to substitute the nvidia 6200tc.
Do you know if it it's better the driver support for ati graphic cards?
Do you know if this bug only happens with ati chipset + nvidia card, or happens also when is ati + ati?
