Installing Debian on Thinkpad X1 Carbon 5th Gen


Debian stable (code name "stretch") installed without any problems, but a few tweaks were in order.

Wireless

Since non free firmware isn't included in Debian, I had to manually download and copy over firmware-iwlwifi to the machine using a USB stick.

Once that was installed, the 4.9.0-6 kernel recognised my wireless network card and I got it up and running with WPA EAP without any problems.

Adjusting screen brightness

I prefer using a command line tool like xbacklight for this. However, it failed with the message:

No outputs have backlight property

To remedy this, I added the following to /etc/X11/xorg.conf to make it locate /sys/class/backlight/intel_backlight:

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

After restarting my login manager, xbacklight worked as it should.

i3

I added these lines to ~/.config/i3/config to make the multimedia keys work:

bindsym XF86MonBrightnessDown exec xbacklight -inc -10
bindsym XF86MonBrightnessUp exec xbacklight -inc 10
