Brightness Key Fix for Lenovo U350 running 10.04

[Betobuntu]

I came across this fix, sadly i dont remember from where. It so that you can use the Fn+Up/Fn+Dn to adjust desired brightness on your display. This worked on a lenovo U350 running 10.04

open terminal type in:

sudo nano /etc/default/grub

Change:

GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash”

to


GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset acpi backlight=video"

also change:

GRUB_CMDLINE_LINUX_DEFAULT=”"

to

GRUB_CMDLINE_LINUX="nomodeset acpi backlight=video"

then run:

sudo update-grub

Awesome fix!! I have been using Ubuntu for a few years now and never cared to find this. This worked on my g530. Thank you
