is a blacklist
- as long as nouveau is loaded, nvivdia will *never* work.


I disable kms and nouvea when I install nvidia, but I do not use packages -
I run their installer.  I also do not use a GUI for anything but mythtv, so
I do not need KMS - Allen might.

Does Ubuntu rebuild it's initramfs after modeproba -a is run.  I put the
blaccklist on the kernel cmdline as well so it is not run from initramfs
(even though I rebuild it).  In Redhat speak, it is
rd.driver.blacklist=nouveau - not sure about debian.
