    Backlight Won't turn on - Gateway!

    Hey all

    Ever since I installed Ubuntu 9.04 onto my Gateway MT3423 Laptop, I've been having issues with my backlight - namely, it works only sporadically. Interestingly enough it will nearly always turn on for a second just before the boot loader appears and also for a second if use the laptop key to use two monitors.

    Any advice?

    Thanks!

    Hi!

    First of all, I'd plug it in to an external monitor, then check if you have all the restricted drivers. Which graphics card does your laptop have?

    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.

    options:
    -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
    Before Executing commands, understand WHAT you are doing and WHY YOU WOULD WANT TO DO THAT. Some Commands can be VERY dangerous if you are uninformed!

    Hey Emanuel - mind telling me how to check for that? I don't even know what restricted drivers I need.... Also, I'm using an NVIDIA GeForce Go 6100 graphics card.

    Don't mind at all! First you go to "System -> Administration -> Hardware Drivers" and see if there are any. If not, the next version of Ubuntu, 10.04, is supposed to have better support for NVIDIA drivers. So you could upgrade to the BETA now, or wait until the full version comes out at the end of the month...
