I have an overheating and excessive fan noise problem with Ubuntu 11.10 on a brand new Toshiba Portege R830-13C laptop. The laptop is dual boot with Windows 7, where I don't have this problem at all, so I'm assuming it's an Ubuntu issue. Any ideas?

I've looked into this myself. As far as I know, it is just an ongoing bug with the 11.10 release--I saw that stated 3 days ago. It happens to my laptop also...this is the first distro version that it's done it with :/ – user36417 Dec 3 '11 at 4:45

There is a known issue with the Active State Power Management (ASPM) in the kernel for Ubuntu 11.10 that effects some laptops - details in this Phoronix article .

You can edit your GRUB cofig file and add some parameters to try to solve the issue;

  1. From a terminal (or after pressing Alt + F2) run:

    gksudo gedit /etc/default/grub

    and enter your password.

  2. Find the line starting with GRUB_CMDLINE_LINUX_DEFAULT and append i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 pcie_aspm=force quiet splash to its end. For example:

    GRUB_CMDLINE_LINUX_DEFAULT="i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 pcie_aspm=force quiet splash"

    Save the file and close the editor.

  3. Finally, start a terminal and run:

    sudo update-grub

    to update GRUB's configuration file (you will need to enter your password).


If pcie_aspm=force is set, hardware that does not support ASPM can cause the system to stop responding. Before setting pcie_aspm=force, ensure that all PCIe hardware on the system supports ASPM.
