I asked this in another forum but nobody answered and I really want to sort this out. I've installed ubuntu 13.10 RC and now I'm experiencing some high temperatures (I experienced this on 13.04 as well). The temps are higher with 10-15C than their equivalents on windows. My notebook is a Sony Vaio S with nvidia graphics 640M LE (hybrid graphics). These temps are as high immediately after installation with zero load.

I tried installing nvidia-current and nvidia-settings which after a restart, when I logged in I was presented with a black desktop with just the cursor. After I uninstalled the nvidia packets and did a clean with auto-remove when I tried logging in again, instead of being redirected to the desktop it kept redirecting me to the login again. BTW, I tried checking the Additional Drivers and it didn't suggest any proprietary drivers to install.

Does anyone have any suggestions with regards to these temps with that model of the nvidia card? If possible I'd like to permanently use the intel card. Are these temps caused by the lack of the nvidia driver or maybe something else?

Thank you.

is the fan working? check that air is being blown out of laptop. In some instances the fan stops and is not started by Linux distros.

You should check out your processes as well using the system monitor or htop, sometimes a program can bug out and run wild or not work properly and cause a run up of recourses. An example once I had my quad desktop over heat because I walked away from a buggy kppp operation that was running my cpu wild. Not sure if it helps but thats my guess.

To get the hybrid graphics working properly you have to use Bumblebee in addition to the Nvidia drivers. I suggest to try that first.
Also, Canonical somehow has "forgotten" to enable the p-state driver for power-management on newer Intel CPUs in Ubuntu 13.10, this could also be your problem, you may want to try it with a self compiled kernel or a different distro than Ubuntu.
