need the binary driver for that.
I was wrong. Seems like the driver installation was so
transparent, I barely noticed anything, at least, bumblebee did
it for me. Though there seems to be no way have vdpau on my
hybrid graphics today.
I don't have performance issues, I have high CPU load in idle
mode. I'm currently on win7 and the cooler seems to be off, in
Ubuntu and Mint the cooler worked at high speed and quite warm
air was coming from the radiator.
Weird. Doesn't happen to me on any distro.
That said, did you look at the system monitor?
System monitor reports some weird information for me: it claims
all processes are sleeping and consume 0% CPU yet on the
processors tab it shows constant load of about 10% jumping from
core to core. Anyway, I switched back to Mint and plan to address
my issues on their forum.
Notice which process is using up the CPU - if it's something in
Unity,
then KDE/XFCE/LXDE/whatever can fix your problem. Unity IS a
resource hog, but it shouldn't cause a permanent load on the
CPU.
There is a possible cause, but that would be GPU, not CPU load:
NVidia stated that they don't intend to support Optimus on
Linux.
What's worse, if you have an Optimus GPU, it runs on 100% all
the time even though you're not using it.
It shouldn't produce heat because there's no load on it.
Bumblebee 3 claims to turn off discrete GPU by default an turn it
on only on demand when an application is run with optirun.
