Title:
  clicking noise on acer 131t-c1yf

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  My machine is solid state.
  I updated the intel graphics driver
  I update a few days ago via ubuntu udpater

  There is a subtle clicking noise coming near from the usb port.  The machine is solid state and the ubuntu is running from the sd card  The noise happnes with usb live boot too.
  The mint 17 usb makes the noise too and then warns me that that the graphics gpu will not be used and then the clicking stops.
   
  Lubuntu installed on top of ubuntu still makes the noise.
  Lubuntu live usb does NOT make the noise.
  Windows 10 does not make the noise.

  I suspect compiz, but ultimately I think it is a kernal problem.
  I suspect this is a CherryView Bug.

  
  This bug has been reported on ubuntu forums and ask ubuntu and no responses.
  I will be switching to Lubuntu in a few days unless I hear back from you.  I am technical and willing to help.
