The following solotuion is what I used when my USB mouse and USB keyboard worked fine at startup but stopped working after a while. I have successfully used it on a Toshiba A100 laptop running Ubuntu 7.04, a.k.a. "Feisty".

Disclaimer: The success (or otherwise) of the following solution will depend on your hardware and possibly which version of *buntu you are using. Feel free to add your feedback to this thread and alternative solutions



  1. From a terminal, type Code:
    gksudo gedit /boot/grub/menu.lst
    You will be asked for your password - don't worry if your password doesn't show, this is normal. Just type in your password as usual, and it will be accepted.
  2. When the editor opens, scroll down to the line which reads and change it to read Code:
    # defoptions=quiet splash acpi=force irqpoll
  3. Save the file, exit the editor
  4. From the terminal, type in Code:
    sudo update-grub
  5. Restart your computer.



But after i enter my password i just get a blank window. Ive tried three different usb mice in two different usb ports and they all do the same thing. Im currently using a P5NSli motherboard and a 1.8ghz C2D. Any help would be greatly appreciated.
