modprobe blacklist help desperately needed.

[Ray Parrish]

Where have you put that blacklist line? I was just looking at the output 
of modprobe earlier tonight. There are a bunch of blacklist lines in the 
configuration file, and they all start at the top, and continue down for 
many, many, pages in the file.

Modprobe is designed for adding things like new blacklist lines to the 
configuration for you, so have a look at "man modprobe" in Terminal to 
discover how to do it. I note that when looking at the output from 
modprobe earlier, even 'though it had my nvidia video card driver 
blacklisted early in the file, it later enables and runs the same driver 
for me according to the later output in the same file.

I had to pipe the output of modprobe through more as there was way too 
much to keep in the scroll buffer in Terminal. Here's the command to 
dump the configuration out where you can look at it before making any 
changes -
modprobe -c  --showconfig | more

"man modprobe" of course will load the manual for you, so you can look 
up how to use it to blacklist, then later run your driver, or whatever 
you have to do with it.

Later, Ray Parrish
