[Bug 1332947] Re: HDPI: unity randomly turns on large text in universal access

 

Has anyone tested the fix in Unity 7.3.1? If yes, please confirm that it
works. It then should be backported to Unity 7.2 as 7.3.1 won't be
backported to Trusty.

Bug description:
  I have a macbook pro with retina display. In Ubuntu 14.04 64bit, every
  couple of reboots, the 'large text' option in Universal Access gets
  switched on upon login. It happens in roughly 1 out of 5 reboots for 1
  or more users on the computer.

  It appears to happen to people with small HighDPI screens. In my case, it's 13 inch at 2560x1600.
  Another example is 13 inch at 1080p -  http://askubuntu.com/questions/453785/large-text-button-in-universal-access-turns-itself-on-after-reboot-ubuntu-14-0
