[SOLVED] Help! I cannot bear Win 8.1 - Installing LL 2.2 on Lenovo U530?

To make the story short , I didn t removed the nouveau driver or whatever that I had on my install , it was left there after rethinking about it .

Ok -- thanks for clarifying.  That's pretty much what I thought, but wasn't sure because I've never had to deal with it.  If it were an already existing NVidia driver on the system, then for sure one would need to purge that ahead of time; but not the nouveau driver.
