[Bug 1537308] Re: System sends Control, Alt and Shift events without input.


Sorry for the delay, my laptop decided it didn't want to use the monitor
when booting from a live CD for some reason, took me a while to figure
out a way around that.

I was able to boot into the Jan 31 nightly, and recreated the problem.
Screen came back on and xev logged a Control_L less than 5 minutes after
the screensaver came on.

  System sends Control, Alt and Shift events without input.

Status in xorg package in Ubuntu:

Bug description:
  I noticed strange behavior from my Ubuntu system.  While left idle,
  the screensaver would shut off with no interaction with the machine.
  While using the machine, webpages would zoom in or out when trying to
  scroll, and command windows would open while typing.

  Using xev, I found that these events corresponded with ALt_L,
  Control_L and Shift_R events, even though those buttons were not being
  pressed.  I'm attaching a xev log, searching for _L will show the
  events.  ((Shift_R events are, for some reason, much rarer and do not
  occur in the particular log I'm adding.)  In many (but not all)
  incidents, the KeyRelease event occurs without a preceding KeyPress
  event.  This problem starts a variable period of time after booting
  the machine; generally within 4 hours.  Once it starts, it persists
  until a reboot.

  Disabling the trackpad with xinput will stop the problem for several
  hours, but eventually something re-enables the trackpad and the
  problem reappears.

  Running memtest on the box generates an error when one specific core
  runs one specific test, but I cannot rule out that being related to
  memtest's problems with UEFI systems.  (See
  passmark.com/forum/showthread.php?5638 for info on my memtest results
  and the UEFI issues.) I returned the machine to HP for service.  They
  replaced the keyboard, trackpad and memory.  This did not resolve the

  I've recreated the problem in UbuntuMate, Ubuntu, and Debian, on both
  3.x and 4.x kernels.  I cannot reliably reproduce the issue on the
  Windows partition on the same box; I think I might have seen it once
  or twice while working on the machine, but can't rule out accidental
  keypresses by me at those times.  Leaving a keylogger running for over
  24 hours on the Windows partition did not show any unexpected keyboard
