Title:
  left mouse button ignored

Status in xserver-xorg-input-evdev package in Ubuntu:
  Expired

Bug description:
  After a random amount of time, the left mouse button gets ignored, regardless of where one tries to click. The other mouse buttons still work. It does not seem to be connected to any particular application.  I never saw the problem in 10.04 or 10.10, but it happens nearly daily in 11.04.  (both 32- and 64-bit)
  I suspect it could be caused by the system failing to notice a key/button release and so try to get out if it by pressing all the keyboard modifier keys and all mouse buttons one by one.   Doing so sometimes helps, other times a reboot is needed to get the left mouse button back.
  As a test, I started "xev" while the system was affected by the bug. It gives ButtonPress and ButtonRelease events for most mouse buttons, but no event is generated when pressing the left button.
  I don't think it is a hardware problem as I've seen it on two computers with different mice.
  There is a discussion thread devoted to the issue too:  http://ubuntuforums.org/showthread.php?t=1750236
