I have an 8500 GT and these are the error messages I get:
error: MM_X_TV_TYPE="HD480P' is not valid for MM_X_DRIVER='nvidia'
error: the 'x' init script does not understand MM_X_TV_TYPE='HD480P'.
error: 'MM_X_MODE' format is not valid
error: check '/var/log/minimyth.err.log' for further details
Not sure if I have a conf file issue or if it's a driver issue. I left MM_X_MODE to default.
Any help much appreciated.
