    How are you doing it now?

    You should be able to do it from Yast - boot

    Can't you be more specific as to where is that "on some line of kernel"?

    Sigh...

    Please, you have to be more talkative. You have to explain exactly what
    you did. In this case, what exact file you edited, and what exactly you
    edited on it. I can make guesses, but it would be preferable that you
    told us :-)

    here we go...

    I edited the grub.cfg file and added acpi_backlight=vendor to the line that start with linux /boot/vmlinuz-3.12.6.5

    tia!

    More, I need more.

    Assuming that you are using grub2, I'd guess that you have edited
    "/boot/grub2/grub.cfg", but you could have saved me guessing and said so
    explicitly, and thus got an explicit answer 6 hours ago.

    Well, changes to that file do not survive. Instead, you have to edit the
    file "/etc/default/grub", this entry:

    Code:
    GRUB_CMDLINE_LINUX_DEFAULT=" resume=/dev/disk/...."
    And then, read the comment at the start of that file, and do what it says:

    Code:
    # If you change this file, run 'grub2-mkconfig -o /boot/grub2/grub.cfg'
    # afterwards to update /boot/grub2/grub.cfg.
