Re: Strange behaviour of Asus U30Jc
This methods might be interesting. Anyhow, since I have no application where I really
need the NVIDIA, I'm trying to switch it off before the XServer is loaded and then
blacklist nouveau. I'm doing this with MacOS and the box works quite well and
it earns me a lot of battery life.
The kernel backtrace in dmesg I was talking about also appears in 10.10 x86_64:(
