Set_Backlight_pet Files

August 22nd 2026 there are two files.

1.- Setbacklight.pet.- @ozsouth original.- "This is a variation on the setbkl script I 've used for some time. Probably won't work for everyone. 

Puts an entry in Utility menu. Allows you to select screen brightness in 10% increments (10-100). Default is 60%."


2.- Setbacklight 1.1 improved.pet   @pp4mnk modded. 

I updated the original package with the improved version.
