I installed Mint on the above mentioned ultrabook.

Even in idle the machine gets really hot really fast. It is almost not possible to touch in on the bottom.

I tried using Bumblebee but it doesn't seem to work at all. I get the following error:

[  933.896850] [ERROR]The Bumblebee daemon has not been started yet or the socket path /var/run/bumblebee.socket was incorrect.
[  933.896916] [ERROR]Could not connect to bumblebee daemon - is it running?

I also tried following this guide: http://tuxtweaks.com/2008/08/how-to-control-fan-speeds-in-ubuntu/

But when I run: sudo pwmconfig

I get this error: # pwmconfig revision 6166 (2013-05-01) This program will search your sensors for pulse width modulation (pwm) controls, and test each one to see if it controls a fan on your motherboard. Note that many motherboards do not have pwm circuitry installed, even if your sensor chip supports pwm.

We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.

/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed

Under Windows 8 everything is running smoth.

What wonders me the most is the fact, that the fan isn't spinning at all. Under Windows 8 I can hear it running.

Any suggestions are welcome!

EDIT: I made some progress. I added the option "acpi=1" to /etc/default/grub. It now looks like this:

GRUB_CMDLINE_LINUX_DEFAULT="radeon.dpm=1 acpi=off"
GRUB_CMDLINE_LINUX="acpi=off"

That seems to let the Laptop not to heat up to much. But the it seems like it doing it by slowing down the CPU. The whole device is running slower and the fan still isn't spinning. There seem to be no options in the BIOS to fix thix issue.
