Debian Jessie on Thinkpad X240

+ + + +
+

Why not Debian Wheezy?

+
+

+I've tried really hard to get the X240 running on Debian Wheezy (Stable), +but after investing days trying to fix basic hardware failures I decided to +move to Debian Jessie (testing). +

+
+
+ +
+

Hardware

+
+
+

Kernel

+
+

+Before you do anything you should get the hardware working correctly. +In order to do that, any Linux kernel image from the +testing/unstable/experimental repositories will work great. +

+ +

+It's known that most hardware components will work properly starting kernel +version 3.12.
+3.13.x and 3.14.x versions only worked for me. +

+ +
+ +
uname -a
+
+
+ +
+Linux raiser 3.14-1-amd64 #1 SMP Debian 3.14.7-1 (2014-06-16) x86_64 GNU/Linux
+
+ +

+This is how your output of lspci should look like. +

Brightness Controls

+
+

+By default, the brightness keys will control stages of the brightness +level. To change that behavior to gradually change the brightness, add +the following line to your /etc/default/grub: +

+ +
+ +
cat /etc/default/grub | grep GRUB_CMDLINE_LINUX_DEFAULT
+
+
+ +
+GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux acpi_backlight=vendor"
+
+ +

+Next update GRUB: +

+ +
+ +
update-grub
+
+
+
+
+ +
+

Intel Graphics

+
+

+By default, X server will enable the hardware acceleration, DRI, and +other GL settings. To enable SNA acceleration for the Intel GPU, +create a configuration file in /etc/X11/xorg.conf.d/ with the +following: +

+ +
+ +
cat /etc/X11/xorg.conf.d/20-intel.conf
+
+
+ +
+Section "Device"
+   Identifier  "Intel Graphics"
+   Driver      "intel"
+   Option      "AccelMethod"  "sna"
+EndSection
+
+
+
+ +
+

Power Saving

+
+
+

Powertop

+
+

+Powertop is a tool that will output the current usage of electricity +by each hardware component, and how it's been managed. +

+ +

+The best feature from Powertop is the Tunables section. In this +section, you're able to fine tune the available power saving modes of +your hardware components. +

+ +

+Start Powertop +

+ +
+ +
sudo powertop
+
+
+ +

+Hit the key <TAB> to browse, and select from a range of tunable +options. Powertop tells you which to change with a description of +Bad. +

+
+
+ +
+

RC6 Kernel Settings

+
+

+The Intel i915 RC6 triggers a lower power state during the GPUs idle +state. +

+ +

+To enable RC6, you need to add the GRUB boot flag: +

+ +
+ +
cat /etc/default/grub | grep GRUB_CMDLINE_LINUX_DEFAULT
+
+
+ +
+GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.i915_enable_rc6=1"
+
+ +

+Next update GRUB: +

+ +
+ +
update-grub
+
+
+ +

+This will enable it on boot, but usually TLP handles RC6 switching +on suspend/hibernation/resume modes. +

+ +

+For more information on Intel i915 power saving settings, see +Ubuntu's Power Saving Tweaks. +

+
+
+ +
+

TLP

+
+

+Everybody in the community recommends TLP for controlling power +usage, and triggering the power saving capabilities of multiple +hardware devices. TLP works well with systemd, and it provides +specific modules for modern Lenovo Thinkpads. +

+
+ +
  • Installation
    +

    +Create a tlp.list file for the tlp repositories in +/etc/apt/sources.list.d/ that contains the following line: +

    + +
    + +
    cat /etc/apt/sources.list.d/tlp.list
+
    +
    + +
    +deb http://ppa.launchpad.net/linrunner/tlp/ubuntu lucid main 
+
    + +

    +Add TLP's keys to the apt keyring with the following command: +

    + +
    + +
    apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 02D65EFF
+
    +
    + +

    +Re-synchronize the packages index and install the TLP's packages: +

    + +
    + +
    apt-get update
+
    +
    + +
    + +
    apt-get install tlp tlp-rdw tp-smapi-dkms acpi-call-tools
+
    +
    + +

    +For more information about the installation process, see TLP's +installation section. +

    +
    +
    • + +
  • Configuration
    +

    +My TLP configuration: +

    + +
    + +
    cat /etc/default/tlp

Touchpad

+
+

+As you already notice, the touchpad is quite peculiar. Itself is a +giant click-button. In the upper section of the touchpad, there are +divisions assigned for each mouse button. It gets time to get used to, +but I prefer it since I mostly use my trackpad. The distance between +the divisions of the mouse buttons and the trackpad is perfect, this +makes the usage of both pleasant. +

+ +

+By default, the divisions of the buttons, two-finger scrolling, and +the sensibility calibration are not set. To enable all of them, set up +a configuration file for the X server in /etc/X11/xorg.conf.d/ +with the following: +

+ +
+ +
cat /etc/X11/xorg.conf.d/50-synaptics.conf
+
+
+ +
+# Synaptics Touchpad configuration for Thinkpad X240

System

+
+
+

systemd

+
+

+systemd is a great tool for managing services and system states. I +won't explain what systemd is, or why you should be using it in +your system. I will only add that, it does have a learning curve, it +goes against all the established patterns for upstarting a system and +its services. +

+ +

+For learning documents and other resources, go to systemd +official website. +

+
+ +
+

systemd for Debian

+
+

+It's redundant to explain how to install and configure systemd in +Debian, when the Debian's wiki covers everything you need. +

+ +

+Visit https://wiki.debian.org/systemd +

+
+
+ + +
+

journalctl

+
+

+journalctl is meant to query the systemd journal. systemd's +journal is an aggregation of most important logs and events occurring +in your system. +

+ +

+In order for the normal user to access journalctl, you must add the +user to the systemd-journal group. +

+ +
+ +
usermod -a -G systemd-journal <your username>
+
+
+ +

+Now reboot systemd: +

+ +
+ +
systemctl reboot
+
+
+
+
+ +
+

NetworkManager

+
+

+By default, NetworkManager.service should be part of the systemd lib +directory, and should be enabled. +

+ +

+You should be able to find the service units for NetworkManager in +/etc/systemd/system/ +

+ +
+ +
cat /etc/systemd/system/dbus-org.freedesktop.NetworkManager.service
+
+
+ +
+[Unit]
+Description=Network Manager
+
+[Service]
+Type=dbus
+BusName=org.freedesktop.NetworkManager
+ExecStart=/usr/sbin/NetworkManager --no-daemon
+# Suppress stderr to eliminate duplicated messages in syslog. NM calls openlog()
+# with LOG_PERROR when run in foreground. But systemd redirects stderr to
+# syslog by default, which results in logging each message twice.
+StandardError=null
+# NM doesn't want systemd to kill its children for it
+KillMode=process
+
+[Install]
+WantedBy=multi-user.target
+Alias=dbus-org.freedesktop.NetworkManager.service
+Also=NetworkManager-dispatcher.service
+
+ +
+ +
cat /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service
+
+
+ +
+[Unit]

+ExecStart=/usr/lib/NetworkManager/nm-dispatcher.action
+
+[Install]
+Alias=dbus-org.freedesktop.nm-dispatcher.service
+
+ +

+You should see that NetworkManager.service is enabled. +

MySQL

+
+

+The MySQL server debian package doesn't contain a unit service for +it. +

+ +

+Here's a version that I wrote myself: +

+ +
+ +
cat /etc/systemd/system/mysqld.service
+
+
+ +
+[Unit]
+Description=MySQL Server
+After=network.target
+
+[Service]
+PermissionsStartOnly=true
+ExecStartPre=/bin/mkdir /var/run/mysqld
+ExecStartPre=/bin/chown -R mysql:mysql /var/run/mysqld
+User=mysql
+Group=mysql
+WorkingDirectory=/usr
+ExecStart=/usr/sbin/mysqld --defaults-file=/etc/mysql/my.cnf --datadir=/var/lib/mysql --socket=/var/run/mysqld/mysqld.sock
+
+[Install]
+WantedBy=multi-user.target
+
+
+
+ + +
+

TLP

+
+

+TLP's Debian package by default, doesn't provide +/etc/systemd/system/tlp.service and +/etc/systemd/system/tlp-sleep.service files for systemd +

+ +

+You can grab this from the TLP's upstream git repository like I did. +

+ +
+ +
cat /etc/systemd/system/tlp.service
+
+
+ +
+# tlp - systemd startup/shutdown service
+#
+# Copyright (c) 2014 Thomas Koch <linrunner at gmx.net>
+# This software is licensed under the GPL v2 or later.
+
+[Unit]
+Description=TLP system startup/shutdown
+After=multi-user.target
+Before=shutdown.target
+
+[Service]
+Type=oneshot
+RemainAfterExit=yes
+ExecStart=/usr/sbin/tlp init start
+ExecStop=/usr/sbin/tlp init stop
+
+[Install]
+WantedBy=multi-user.target
+
+ +
+ +
cat /etc/systemd/system/tlp-sleep.service
+
+
+ +
+# tlp - systemd suspend/resume service
+#
+# Copyright (c) 2014 Thomas Koch <linrunner at gmx.net>
+# This software is licensed under the GPL v2 or later.
+
+[Unit]
+Description=TLP suspend/resume
+Before=sleep.target
+StopWhenUnneeded=yes
+
+[Service]
+Type=oneshot
+RemainAfterExit=yes
+ExecStart=/usr/sbin/tlp suspend
+ExecStop=/usr/sbin/tlp resume
+
+[Install]
+WantedBy=sleep.target
+
+ +

+After that enable both services. +

+ +
+ +
systemctl enable tlp.service
+
+
+ +
+ +
systemctl enable tlp-sleep.service
+
+
+ +

+Now check that everything is working properly. +

+ +
+ +
systemctl status tlp.service
+
+
+ +
+tlp.service - TLP system startup/shutdown
+   Loaded: loaded (/etc/systemd/system/tlp.service; enabled)

acpid

+
+

+systemd and acpid with acpi-support both offer the same +capabilities for events triggered by hardware, specifically, the ACPI +calls. For example, closing the lid to suspend a laptop. +

+ +

+For instance, by default, the closing the lid will trigger acpid to +call the suspend state of pm-utils, but at the same time +systemd recognizes the closing action which in the same case will +trigger suspend actions in systemd. +

+ +

+In order to avoid these, we have to disable the action in either +acpid or systemd. +

+
+ +
  • Disable Lid action
    +

    +To disable this in acpid, modify /etc/acpi/events/lidbtn, and +comment all of the lines. +

    + +
    + +
    cat /etc/acpi/events/lidbtn
+
    +
    + +
    +# /etc/acpi/events/lidbtn
+# Called when the user closes or opens the lid
+
+#event=button[ /]lid
+#action=/etc/acpi/lid.sh
+
    + + +

    +To disable this in systemd, modify /etc/systemd/logind.conf, and +change the key HandleLidSwitch to ignore: +

    + +
    +HandleLidSwitch=ignore
+
    +
    +
    • + +
  • Enable Lid suspend action in systemd
    +

    +To enable suspend on closing the laptop lid, disable the acpid's +like mentioned above. Change the key HandleLidSwitch to suspend in +/etc/systemd/logind.conf: +

    + +
    +HandleLidSwitch=suspend
+
    +
    +
+
+
