D5381: Add brightness control using ddcutil lib

[Dorian Vogel]

dvogel updated this revision to Diff 13586.
dvogel added a comment.


  Addition of a QTimer set by default to 1 sec to filter setBrightness calls: the actual DDC communication happens 1 sec after the last setBrightness() call.
  This solves brightness flickering when scrolling quickly on the battery icon, and communication failure over DDC when waking the monitor from power-save mode (Dell U2212HM wakes up in less than 1 sec).
