Arch Linux Laptop (Lenovo Thinkpad X250) Monitor Brightness

for xfce4 fn+F5 and fn+F6 work fine but for i3 it didn’t work.

if trying to change backlight brightness by xbacklight -inc 10 then get error message

No outputs have backlight property

so added /etc/X11/xorg.conf

Section "Device"
    Identifier "Card0"
    Driver "intel"
    Option "Backlight" "intel_backlight"
EndSection

But it failed starting Xserver because system coudn’t load intel package. The system couldn’t load intel because it doesn’t have intel driver and using modesetting.

And according to arch wiki, xbacklight command will not work with modesetting.

Now I decided to replace xorg-xbacklight to acpilight.
acpilight is AUR package and its backward compatible xbacklight replacement.

Installed it from AUR and copy 90-backlight.rules to /etc/udev/rules.d/

Now xbacklight work fine!

new laptop (lenovo Thinkpad X250) Windows 10 Arch Linux Dual Boot

I bought new laptop lenovo ThinkPad X250 installed Windows 10 professional edition.
It was second hand laptop I found in sofmap Kobe.
It has Intel core i5, 8GB RAM, 500GB HDD and price was 66000 Yen (roughly $600).
I didn’t need it immediately but its spec and price was appealing to me so I bought it.

Here is record of installing arch linux on this machine.

Referenced YouTube video

I know official Arch Linux website strongly insists that we should follow official installation guide especially if you are a newbie and discourage to just follow random YouTube installation video. I totally agree about that. I totally agree about that. I referenced this YouTube video but I also read official installation guide too and understand what’s going on in each steps in video since I had installed arch linux several times.

Installation process was almost same as shown in referenced YouTube video. The process was really smooth because I had done before and better understand the installation process than I was complete newbie.

The major difference from previous my installation was it’s dual boot system with windows 10. So I need to create free partition for new arch linux on windows system and I don’t need to create efi boot partition because it’s already there.
