Can anyone provide a workaround first? For example how to prevent light
sensor from working at all, disable the module or kernel feature that
uses it.

Title:
  light sensor misjudge ambience light

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Running Ubuntu 14.04 on bModo12 (same hardware as WeTab). When running
  on battery, the screen changes brightness frequently, by itself, while
  there are little change in ambience light. In fact, if I just place it
  stablly on the table and observe from distance, it turns bright and
  dark all by itself happyly, once a few seconds. It is unbearable to
  use.

  I installed brightness control applet "indicator-brightness", and
  hoped manual control overwrites automatic ambience light sensor. But
  no, automatic sensor overwrites manual setting. If I set brightness to
  10, for example, it is bright for one second, and back to darkness.

  I urgenly need a workaround - a method to turn off light sensor and
  force always brightest light output. Kindly offer a workaround before
  solving this bug. Thanks!

  My hardware and system is the same when I reported bug 1318639 - and the bug always exists since I installed the OS in day 1.
  Inform me if you insist on a new machine-generated PC/OS information set.
