Terminal/adding codes help :)

[edward1100]

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
