Re: Backlight Won't turn on - Gateway!
Likely not due to Linux.
I've worked on Laptops as a benchtech and can tell you....if the light isn't lighting up, the backlight is likely bad. The LCD backlight is always on, the light level is software controlled (BIOS) via key combination.
-Find a place that fixes them and have it repaired (probably not worth it)
-Find a the same model laptop on ebay that is for parts only...cannibalize the LCD. (worth the time if you can find it on the cheap)
-Replace the laptop. Walmart has an HP full sized laptop for $348 and a more powerful model for $528
