[Solved] Issue with brightness settings?

[kmacmart@darkcloud.ca]

62 and 70 are the Brightness I2C address so the controller should work.

What exactly happen when you move the brightness slider, the utility crashes or the screen brightness stay the same or something else?

I can't get as far as being able to move the brightness slider; it loads the screen you're seeing in the screenshot from my first post with the error at the bottom and then returns to the previous menu.

Good to hear this is likely a software issue though! Do you think maybe the June 6th image has a bug in the script?
