Title:
  keyboard and/or mouse freezing

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Ubuntu 10.04
  This bug does not occur all of the time and it makes it usually appears at the GNOME login screen.
  Sometimes at the login screen, when I click on my username, the keyboard will freeze and I will not be able to input anything through the keyboard, or the first or second letter that I type will endlessly repeat itself as though I have my finger on the keyboard.  In other instances, when I click on my username and start entering my password, the mouse will freeze.

  Other times, the keyboard or mouse will freeze after I have logged in.
  Sometimes the system will have operated fine for over an hour and then
  suddenly the mouse no longer responds or the keyboard freezes or
  starts repeating a keystroke.  If I have already logged in, sometimes
  BOTH the mouse and keyboard will freeze so that I can't do anything
  other than hit the reset button.

  My mouse is plugged into a USB port, but using an adapter to plug it
  into the PS/2 plug does not rectify the problem.

  The problem appears to repeat consistently if my Epson CX8400 printer
  is turned on at start-up.  It is plugged into a USB port.  I have
  noticed that if I turn the printer on after logging in, Ubuntu will
  not detect the printer, but leaving it on while starting up simply
  leads to freezing.

  I am using an Asus P4S800 motherboard.

  Mouse and keyboard freezing at login occurred consistently (almost
  every login attempt) prior to changing from the default display
  manager to the NVIDIA display manager.

  Keyboard freezing does not occur in GRUB.
  If I start Ubuntu 10.04 in recovery mode and use "gdm" to get to the login screen, freezing does not appear.
