Yeah, agreed! Shakes hurt my eyes.. I just installed Atom because of this cool plugin, lol.

I agree.

I change the intensity in activate-power-mode.coffee to 0. Now it doesn't shake any more.

Thanks for the tip @grjiq it doesn't shake anymore!

as per 0.4.1 the config config.cson will be

"*":
  "activate-power-mode":
    screenShake:
      enabled: false

before 0.4.1, I'm very appreciate @grjiq @markpanado , I have solved the problem!

$  cd ~/.atom/packages/activate-power-mode/lib
$ vim activate-power-mode.coffee
# comment below code and chang it
# intensity = 1 + 2 * Math.random()
intensity = 0

finally, reload the Atom

Fixed in 0.4.0.

In activate-power-mode version 1.10, I opened the 'config-schema.coffee' file and changed the default value of screenShake to false. Restarted atom. and it stopped shaking.
