this was discussed here not long ago.
you are probably using nvidia drivers (mid-2010 mini?)
create a configuration with nvidia-xconfig if you haven't done so
then add to the "Device" section:
Option "UseHotplugEvents" "false"
You will also probably want to look into the CustomEDID option, so you
can boot and start the mini without having to have the TV first on
