    Re: Unable to adjust screen brightness

    What is in your /proc/acpi/video directory? There should be a brightness file in there somewhere I think. It was my mistake on suggesting smartdimmer as that is for use with GeForce cards and you don't have one. I think you would then need to chmod the brightness file to make it executable and then do the following:

    Code:
    sudo brightness 10
    which would set the brightness level to 10. I hope I'm remembering this correctly.

    Code:
    chasen@Shadow-II:~$ cd /proc/acpi/video/
    chasen@Shadow-II:/proc/acpi/video$ ls
    GFX0
    chasen@Shadow-II:/proc/acpi/video$ cd GFX0/
    chasen@Shadow-II:/proc/acpi/video/GFX0$ ls
    DD01  DD02  DD03  DD04  DD05  DOS  info  POST  POST_info  ROM
    chasen@Shadow-II:/proc/acpi/video/GFX0$

    each of those DD0 directories have a brightness file, they are all blank except for the one in DD03. Changing this file has no effect on my brightness.

    I created my own thread before I even saw this one.
