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.

Configuration

Display

The graphics card is a an on-board Intel card; using lspci it shows up as 

00:02.0 VGA compatible controller: Intel Corporation Broadwell-U Integrated Graphics (rev 09)

It works out of the box, no configuration is required.

OpenGL/3D Acceleration

The drivers are available in backports (https://unix.stackexchange.com/questions/207855/cant-get-intel-hd-5500-graphics-to-work-with-debian)

Switch to External Screen

Multiple external displays through the dock are not supported in the stable kernel. But some solutions are available to use more than one external screen:

  1. Use VGA and mini Display Port
  2. Use the mini Display Port and one of the ports of the docking station
  3. install the 4.x kernel from testing/unstable and use the ports of the docking station (caution, I had trouble with the trackpoint using the testing kernel)

Audio

Using lspci, the sound card shows up as follows: 

00:03.0 Audio device: Intel Corporation Broadwell-U Audio Controller (rev 09)
00:1b.0 Audio device: Intel Corporation Wildcat Point-LP High Definition Audio Controller (rev 03)

The drivers work out of the box, although it might still happen that no sound can be played. Most probably this is because the ordering of the sound cards, detected by ALSA, is wrong. Check using cat /proc/asound/cards 

 0 [HDMI           ]: HDA-Intel - HDA Intel HDMI
                      HDA Intel HDMI at 0xf1230000 irq 64
 1 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xf1234000 irq 61

In this case, a new file /etc/modprobe.d/sound.conf should be created with the following content: 

options snd_hda_intel index=1 model=thinkpad

This will change the ordering of the cards. If sound is still not working, try to press fn + f3 or fn + f4; when accidentally the sound card gets muted using the fn key, ALSA is unable to unmute the sound output again. Pressing the mentioned key combinations should bring back sound in this case.

Mouse

Power Management

To get better battery life time, the package laptop-mode-tools should be installed. 

sudo apt-get install laptop-mode-tools

WiFi

To get WiFi working, the non-free firmware must be installed. The procedure is described here.
