Ubuntu 11.04 Laptop Freeze & Mouse Issues

I'm running Ubuntu 11.04 (Natty Narwahl) on a Toshiba Portege laptop and a few problems when the laptop is running on the battery.

  • The system freezes / locks up and the Toshiba fan goes into high speed mode
  • The mouse doesn't work (although the trackpad does)
  • The screen eventually shifts to the lowest brightness and the brightness cannot be increased
  • Executing the dpkg -s laptop-mode-tools command shows that I'm running version 1.57-1 . For the time being, I'd rather sacrifice the battery saving features provided by the laptop-mode and disable it entirely. To do this, I edited the /etc/laptop-mode/laptop-mode.conf file to disable the tools.

    ENABLE_LAPTOP_MODE_TOOLS=0

    The change should take effect immediately.

    Updated: June 23, 2011

    In the month since I made the change described above I continue to have the system freezes although they don't seem as frequent and I also have periodic issues with the mouse that are resolved by using the touchpad.
