Public bug reported:
The display is dimming after a few seconds of "inactivity" despite
turning off the setting to dim the display. This seems to occur on any
power setting and a reboot did not solve the problem. This makes
activities such as reading difficult as the display becomes harder to
read and I have to interact with the computer more than necessary to
keep the screen bright.
