Ubuntu 18.04をインストールしたLet's note CF-NX2で輝度調節をする

Last updated at Posted at 2018-11-19

Let's note CF-NX2にUbuntu18.04をインストールしたら、輝度調節ができなくて詰んだので、一晩丸々つかって、いろいろ試した。

LinuxMint 19でも動作確認済み
##手順1

/etc/default/grubを開いて、

GRUB_CMDLINE_LINUX="acpi_osi="

にして保存する。
その後、update-grubする。

##手順2

/usr/share/X11/xorg.conf.d/20-intel.confを作成し、以下のように入力し保存

        Identifier  "card0"
        Driver      "intel"
        Option      "Backlight"  "panasonic"
EndSection

再起動して、調節できるか確認
