There is no nf file in 12.10 that I have found, so the solutions that suggest editing that file don't do me a whole lot of good. In /etc/default/grub: GRUB_CMDLINE_LINUX_DEFAULT='quiet splash 'RegistryDwords' 'EnableBrightnessControl=1' Things I have tried include:Įditing /sys/class/backlight/acpi_video0/brightness I've tried all the solutions I could find around the Internet but none of them work.
It is set to the brightest setting when I boot up and when I try to change it, I see the notification bar come up but the brightness doesn't actually change. My brightness control doesn't work with a fresh install of 12.10 (brand new laptop).
