I have a MSI GS70 laptop with Ubuntu 13.10 installed. Unfortunately, my laptop has an NVidia graphics card, the only effect of which for me is constant fan noise, hot temperature of the laptop and drastical power drain (powertop reports 36–40W instead of 24W).

How do I disable this NVidia card?

I found a way to do this: here is a very nice guide on how to turn off the NVidia card. But use it with caution! When I followed this guide, I couldn't boot my system anymore, there was Kernel panic. But here is a workaround. Just change:

# echo "blacklist nouveau" >> /etc/modprobe.d/blacklist

to:

# echo "blacklist nouveau" >> /etc/modprobe.d/blacklist.conf

and it should work. At least it worked for me.
