    Terminal/adding codes help :)

    Hi everyone,

    I've just installed ubuntu 12.04 on my lenovo laptop. This is the first time that I've ever used ubuntu so I'm still very much getting used to it. Once I installed ubuntu, I noticed that the brightness on my laptop doesn't changed when I try to change the brightness in the settings. I have found out how to fix this -

    I need to add the code:

    acpi_backlight=vendor

    to the code:

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

    This will sound like such a stupid question but I don't know what it means to add a code to another code :S

    Something to do with the terminal??

    Thanks in advance.

    hey, you know, every one has been lost the first time; no need to worry

    open the terminal, and run:
    sudo gedit /etc/default/grub
    change the line to looks like : GRUB_CMDLINE_LINUX_DEFAULT=" acpi_backlight=vendor quiet splash"
    then you need to save that file and exit
    and finally update the boot loader:
    sudo update-grub
    Thats it
