Thank you for taking the time to report this bug and helping to make
Ubuntu better. This sounds like a kernel or X.org problem - certainly
not openssh - so reassigning.

** Package changed: openssh (Ubuntu) => linux (Ubuntu)

Title:
  hp x360 laptop keyboard freezes for 1 sec. every few minutes

Status in linux package in Ubuntu:
  New

Bug description:
  A couple weeks ago Installed ubuntu 14.04 on an hp spectre x360.  It
  works great except for a strange keyboard problem.  Every 2 or 3
  minutes the keyboard freezes for about 1 second - it misses keystrokes
  completely.   Anything typed during that 1 second period is missed.
  For that same period, the LED in the F5 key turns off.  The F5 key is
  normally illuminated. If you hit it, that turns the LED off and turns
  on the keyboard backlight.  Hit it again, and the backlight goes off
  and F5 lights up again.  Apparently while that light is out, the
  keyboard is disabled.

  I wrote a program that printed a variable character pattern to a
  terminal every 4 times/sec  and just watched it. I wanted to know if
  the whole computer (or just whole desktop?) was freezing, or just the
  keyboard.  When the keyboard light turned off, the program kept
  running, so I think it's just the keyboard.

  The timing of the light blinking off is variable.  If I am not typing, the light seems to blink at a 2min 30 sec.to 3min 30 sec period.  It seems more often than that when I am actually typing, perhaps 2 minutes.  I'm guessing this is a keyboard driver problem?  Anyone else seen this?
