sorry for insisting on this particular point
However, it seems no one found the solution yet though it makes the TV out unusable :
with a geforce 6600, ubuntu dapper, the TV out always flickers _a lot_ (that is to say, it's unbearable). However with the previous version, it used to work perfectly. I didn't change everything and tried many combinations of xorg.conf settings :'(
Does anyone have an idea ?
Just in case, I attach my xorg.conf file
PS : also, but this is less serious, the nvidia-settings settings are only restored when I relauch nvidia-settings
Thanks for reading
