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. |

Audio
works out of the box (this needs confirmation, as after playing with sound settings PulseAudio cannot play via built-in speakers). 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.
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.
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
Power Management

- works with Non-Free drivers. "non-free" section in /etc/apt/sources.list is required
sudo apt-get install firmware-iwlwifi network-manager
