This isn't really a problem with powerd. As far as I know there's no
standard interface (and likely as not no interface at all) for telling
an input driver to stop sending events other than closing the input
device, and powerd can't close the device on behalf of another process.
The input stack needs to close the input device (preferably, or else
stop listening to events from the touchscreen input device) whenever the
screen is off.

Title:
  Digitiser still works when phone locked

Status in Music application for Ubuntu devices:
  Invalid
Status in PowerD:
  Confirmed
Status in “powerd” package in Ubuntu:
  Confirmed

Bug description:
  Boot Ubuntu on a Nexus 4
  Open music app
  Start playing songs
  Tap the power button to lock the screen
  Swipe in from left or top edge
  Tap the power button to unlock the screen
  Observe the launcher (left) or indicator (top) have opened, while the screen was 'locked'

  Reproduced this on #106 and #111, only happens if you launch music
  first and play music it seems. Launching music and _not_ playing a
  song isn't sufficient to trigger this.

  Here's a video showing it. https://www.youtube.com/watch?v=0Y_JoVfzDmA
