Please try to include some basic information with your questions. As it stands almost all of the questions that you have made are not presented in such a way that it is easy to help. – Chris Down Nov 13 '12 at 21:25
Please add more information. What version of the nvidia-driver are you currently using? How did you install/activate it? What make.conf are you talking about? Have you DKMS installed as well? – Nils Nov 13 '12 at 21:27
wait i'm looking for these questions . /etc/portage/make.conf (for Gentoo it's main file) – Xsi Nov 13 '12 at 21:47
Okey , i'm accustomed user of Q&A google (it's btw not serious at all) - so I'ts hard time for me to getting on with all this. More work less shortness of questions for audience... Trying to be more serious (eager to ..but habits(( I'll try. Maybe all my questions'd disappear or fulfilling myself or they would reemerge again with more vital argumentation. – Xsi Nov 13 '12 at 21:51

You can't expect to use the proprietary nvidia driver's tools when you're running the open source nouveau driver.
