DebianOn is an effort to document how to install, configure and use Debian on some specific hardware. Therefore potential buyers would know if that hardware is supported and owners would know how get the best out of that hardware.

The purpose is not to duplicate the Debian Official Documentation, but to document how to install Debian on some specific hardware.

If you need help to get Debian running on your hardware, please have a look at our user support channels where you may find specific channels (mailing list, IRC channel) dedicated to certain types of hardware.

Important Note

If you are planning on using an Ultradock with external monitors, make sure you upgrade the dock firmware in Windows before installing Debian, otherwise, you may run into frozen display problems.

Also before installing Debian, I disabled these two unnecessary things in the BIOS, just to be safe:

Configuration

Audio

The snd_hda_intel driver included in alsa-base works out of the box.

However, garbled sound can be heard from some applications that use alsa directly so you may want to set this in /etc/libao.conf:

default_driver=pulse

Dock audio

The audio jack on the Ultradock doesn't work. To fix it, put this in /lib/firmware/hda-jack-reconfigure.fw:

[codec]
0x10ec0292 0x17aa220e 0

[pincfg]
0x16 0x2121101f
0x19 0x21a11030

and this in /etc/modprobe.d/hda-jack-reconfigure.conf:

options snd-hda-intel patch=hda-jack-reconfigure.fw,hda-jack-reconfigure.fw,hda-jack-reconfigure.fw,hda-jack-reconfigure.fw

HDMI audio

If the speed / pitch of audio on the HDMI output is off, try using this option on the kernel command line:

i915.disable_power_well=0

Mouse

To disable the touchpad and only leave the top row to simulate trackpad buttons, put the following configuration in /etc/X11/xorg.conf.d/thinkpad_clickpad.conf:

Section "InputClass"
    Identifier "tp only with clickpad buttons"
    MatchDriver "synaptics"
    Option "HasSecondarySoftButtons" "on"
    Option "SecondarySoftButtonAreas" "58% 0 0 8% 42% 58% 0 8%"
    Option "AreaBottomEdge" "1" #disable moving but not buttons
EndSection

This required me to grab version 1.8.0 of the xserver-xorg-input-synaptics package out of experimental.

Power Management

Suspend-to-RAM works out of the box. To prevent the laptop from suspending when the lid is closed, set the following in /etc/systemd/logind.conf:

HandleLidSwitch=lock

If you use laptop-mode-tools, you will need the following in /etc/laptop-mode/conf.d/lcd-brightness.conf to configure the brightness of the screen:

BATT_BRIGHTNESS_COMMAND="echo 70"
LM_AC_BRIGHTNESS_COMMAND="echo 100"
NOLM_AC_BRIGHTNESS_COMMAND="echo 100"
BRIGHTNESS_OUTPUT="/sys/class/backlight/acpi_video0/brightness"

WiFi

Wireless did not work out-of-the box, but required installation of the non-free Debian package firmware-iwlwifi.
