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.

Display

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

1920x1080 native screen resolution
not sure howto verify 2D/3D hardware acceleration
from the look how windows move and resize, I can tell it's software rendered
also Xorg.0.log shows this entry: (EE) AIGLX: reverting to software rendering
Was able to render with hardware acceleration by installing an experimental package, xorg-video-intel_2.99.917-1~exp1_amd64. Use this at your own risk, it's in the experimental repo. However, the defauls settings had some bugs, in that scrolling of some text fields resulted in black bars that made reading impossible. This has been solved by writing a configuration file so that the acceleration method used is 'uxa' (I believe the default method is 'sna'). Also tried 'glamor' method but this resulted in a similar bug. 'uxa' worked flawlessly thus far. Have done limited testing and will report possible problems if they come up. Tests have included HD video playback, successfully using sleep mode, and use of HTML5 750p video streaming. The change in configuration was done by creating a configuration file in the following location: /etc/X11/xorg.conf.d/20-intel.conf. The file contains the following:

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "AccelMethod"  "uxa"
EndSection

Gnome on Wayland runs with hardware acceleration. However, the environment was otherwise unstable, such as windows hanging after some time and no longer responding to clicks or drags. This needs to be tested further for details and was true with a fully upgraded system as of 27 April 2015.
with a backports kernel I had much better graphics experience when using xserver-xorg-video-intel from backports:

apt-get -t jessie-backports install xserver-xorg-video-intel

Audio

Audio works out of the box. The first sound device is Intel HDMI, the second Intel PCH. So applications using "first ALSA device" won't play via the speakers.

cat /proc/asound/cards
 0 [HDMI           ]: HDA-Intel - HDA Intel HDMI
                      HDA Intel HDMI at 0xe1230000 irq 66
 1 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xe1234000 irq 65
29 [ThinkPadEC     ]: ThinkPad EC - ThinkPad Console Audio Control
                      ThinkPad Console Audio Control at EC reg 0x30, fw unknown

To reorder sound cards (and PulseAudio will see both cards) edit 2 files and reboot (not sure which one actually does the difference):

# cat ~/.asoundrc
defaults.pcm.card=1

# cat /etc/modprobe.d/thinkpad-t450s.conf
options snd_hda_intel index=1,0

In pavucontrol I had to disable Configuration => (1st) Built-in Audio (Digital *). And leave Analog Stereo Duplex enabled.

This way google-chrome and skype output sound properly.

Using the PulseAudio Volume Control also allows audio to be pushed to an external display (like a TV) via the mini ?DisplayPort. You will need to open the volume control panel and select the "Built-in Audio Digital Stereo (HDMI)" option for the application that is creating the sound. This option seems to only appear while the application is actively producing audio, so you may need to start the video/music before opening the volume control panel.

Dockingstation

The dvi-expander is a kernel module that is not working in current stable jessie (3.16) -> the result is that only one external monitor can be plugged into the dockingstation. Solution: install the backports kernel (4.1). More information here [1]. After adding following line to /etc/apt/sources.list

deb http://http.debian.net/debian jessie-backports main contrib non-free

The following command shows the available kernel-images

apt-get install update
apt-cache search linux-image

Now choose the most recent kernel-image <KERNEL-IMAGE> and execute following command (in my case linux-image-4.1.0-0.bpo.2-amd64)

apt-get -t jessie-backports install <KERNEL-IMAGE>

Now restart - grub should have a new entry with the new kernel which should be loaded automatically.

Camera

works out of the box. Tested with: vlc => Open => Capture Device (/dev/video1)

Touchpad

Touchpad: 2-finger scrolling works out of the box
Trackpad buttons: Left/Right work as ?MouseWheel buttons. Middle doesn't work. Had to use imps driver to bring back proper behaviour, but that removes 2-finger scroll on touchpad

To use imps driver add this file and reboot:

$ cat /etc/modprobe.d/psmouse.conf 
options psmouse proto=imps

Note: There are reports that kernel 3.19x fixes the problem, so that trackpad, trackpoint, and touchpad work without restrictions. Needs to be confirmed.
Note: Tested with kernel 4.0.0-trunk-amd64. The left and right buttons are working without restrictions for the trackpad. In one test, system loaded fine, with excellent trackpad response, yet wireless/wifi functionality was disabled.
Note: Some versions seem to detect a click halfway between left and right as being a middle click. In this case, the default driver can be used.

Trackpoint scrolling

To enable scrolling using the trackpoint and the middle mouse button, place the following under /usr/share/X11/xorg.conf.d/90-evdev.conf

Section "InputClass"
    Identifier "Touchpad/TrackPoint"
    MatchProduct "PS/2 Synaptics TouchPad"
    MatchDriver "evdev"
    Option "EmulateWheel" "1"
    Option "EmulateWheelButton" "2"
    Option "Emulate3Buttons" "0"
    Option "XAxisMapping" "6 7"
    Option "YAxisMapping" "4 5"
EndSection

Note that these settings will cause the system to recognize both the trackpoint and trackpad as a single, PS/2 device, and you will be unable to use two-finger scrolling or disable the trackpad while typing.

Fn Hotkeys

3.16.0-4 amd64 kernel loads thinkpad_acpi module.

xbindkeys can handle some of Fn keys: XF86MonBrightnessDown, XF86MonBrightnessUp, XF86AudioRaiseVolume, XF86AudioLowerVolume (the rest was not tested)

I did not test default behaviour of the keys in Gnome or KDE.

On Window Maker I had to bind keys manually to custom scripts. In order for brightness adjustments to work following script is bind to the key via xbindkeys

#run as root
#!/bin/bash
BRIGHTNESS_FILE=/sys/class/backlight/intel_backlight/brightness
STEP=50
current=`cat $BRIGHTNESS_FILE`
new=`expr $current + $STEP`
echo $new > $BRIGHTNESS_FILE

Switch between Fn and F1-F12 keys

Fn+Esc enables/disables the Fn key lock.

Power Management

(not covered yet)

WiFi

works with Non-Free drivers. "non-free" section in /etc/apt/sources.list is required

sudo apt-get install firmware-iwlwifi network-manager

with a backports kernel I had to install firmware-iwlwifi from backports or else iwconfig was not showing wlan0:

apt-get -t jessie-backports install xserver-xorg-video-intel

Bluetooth

works out of the box

sudo apt-get install bluedevil blueman
