<div class="outline-text-2" id="text-1">
<p>
I've tried really hard to get the X240 running on <b>Debian Wheezy</b> (Stable),
but after investing days trying to fix basic hardware failures I decided to
move to <b>Debian Jessie</b> (testing).

<h3 id="sec-2-1">Kernel</h3>
<div class="outline-text-3" id="text-2-1">
<p>
Before you do anything you should get the hardware working correctly.
In order to do that, any Linux kernel image from the
<i>testing/unstable/experimental</i> repositories will work great.
</p>
<p>
It's known that most hardware components will work properly starting <i>kernel
version</i> <b>3.12</b>.<br >
<b>3.13.x</b> and <b>3.14.x</b> <i>versions</i> only worked for me.

<h3 id="sec-2-2">Brightness Controls</h3>
<div class="outline-text-3" id="text-2-2">
<p>
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 <code>/etc/default/grub</code>:
</p>
<div class="org-src-container">
<pre class="src src-sh">cat /etc/default/grub | grep GRUB_CMDLINE_LINUX_DEFAULT
</pre>
</div>
<pre class="example">
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux acpi_backlight=vendor"
</pre>

<div class="outline-text-3" id="text-2-3">
<p>
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 <code>/etc/X11/xorg.conf.d/</code> with the
following:
</p>
<div class="org-src-container">
<pre class="src src-sh">cat /etc/X11/xorg.conf.d/20-intel.conf

<h4 id="sec-2-4-1">Powertop</h4>
<div class="outline-text-4" id="text-2-4-1">
<p>
<b>Powertop</b> is a tool that will output the current usage of electricity
by each hardware component, and how it's been managed.
</p>
<p>
The best feature from <b>Powertop</b> is the <i>Tunables</i> section. In this
section, you're able to fine tune the available power saving modes of
your hardware components.
</p>
<p>
Start <b>Powertop</b>
</p>
<div class="org-src-container">
<pre class="src src-sh">sudo powertop
</pre>
</div>
<p>
Hit the key <TAB> to browse, and select from a range of tunable
options. <b>Powertop</b> tells you which to change with a description of
<i>Bad</i>.

<h4 id="sec-2-4-2">RC6 Kernel Settings</h4>
<div class="outline-text-4" id="text-2-4-2">
<p>
The <i>Intel i915</i> RC6 triggers a lower power state during the GPUs idle
state.
</p>
<p>
To enable RC6, you need to add the GRUB boot flag:
</p>
<div class="org-src-container">
<pre class="src src-sh">cat /etc/default/grub | grep GRUB_CMDLINE_LINUX_DEFAULT
</pre>
</div>
<pre class="example">
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.i915_enable_rc6=1"
</pre>
<p>
Next update GRUB:
</p>
<div class="org-src-container">
<pre class="src src-sh">update-grub
</pre>
</div>
<p>
This will enable it on boot, but usually <b>TLP</b> handles RC6 switching
on <i>suspend/hibernation/resume</i> modes.
</p>
<p>
For more information on <i>Intel i915</i> power saving settings, see
<a href="https://wiki.ubuntu.com/Kernel/PowerManagement/PowerSavingTweaks">Ubuntu's Power Saving Tweaks</a>.

<h4 id="sec-2-4-3">TLP</h4>
<div class="outline-text-4" id="text-2-4-3">
<p>
Everybody in the community recommends <b>TLP</b> for controlling power
usage, and triggering the power saving capabilities of multiple
hardware devices. <b>TLP</b> works well with <b>systemd</b>, and it provides
specific modules for modern <b>Lenovo Thinkpads</b>.
</p>
</div>
<ul class="org-ul"><li>Installation<br ><div class="outline-text-5" id="text-2-4-3-1">
<p>
Create a <code>tlp.list</code> file for the <b>tlp</b> repositories in
<code>/etc/apt/sources.list.d/</code> that contains the following line:
</p>
<div class="org-src-container">
<pre class="src src-sh">cat /etc/apt/sources.list.d/tlp.list
</pre>
</div>
<pre class="example">
deb http://ppa.launchpad.net/linrunner/tlp/ubuntu lucid main
</pre>
<p>
Add <b>TLP</b>'s keys to the apt keyring with the following command:
</p>
<div class="org-src-container">
<pre class="src src-sh">apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 02D65EFF
</pre>
</div>
<p>
Re-synchronize the packages index and install the <b>TLP</b>'s packages:
</p>
<div class="org-src-container">
<pre class="src src-sh">apt-get update

</div>
<div class="org-src-container">

<p>
As you already notice, the touchpad is quite peculiar. Itself is a
<i>giant click-button</i>. 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 <i>trackpad</i>. The distance between
the divisions of the mouse buttons and the <i>trackpad</i> is perfect, this
makes the usage of both pleasant.
</p>
<p>
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 <i>X server</i> in <code>/etc/X11/xorg.conf.d/</code>

<b><i>systemd</i></b> is a great tool for managing services and system states. I
won't explain what <b><i>systemd</i></b> 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.

<b><i>systemd</i></b> and <b>acpid</b> with <i>acpi-support</i> both offer the same
capabilities for events triggered by hardware, specifically, the ACPI
calls. For example, closing the lid to suspend a laptop.
</p>
<p>
For instance, by default, the closing the lid will trigger <b>acpid</b> to
call the <i>suspend</i> state of <i>pm-utils</i>, but at the same time
<b><i>systemd</i></b> recognizes the closing action which in the same case will
trigger <i>suspend</i> actions in <b><i>systemd</i></b>.
</p>
<p>
In order to avoid these, we have to disable the action in either
<b>acpid</b> or <b><i>systemd</i></b>.
</p>
</div>
<ul class="org-ul"><li>Disable Lid action<br ><div class="outline-text-5" id="text-3-1-6-1">
<p>
To disable this in <b>acpid</b>, modify <code>/etc/acpi/events/lidbtn</code>, and
comment all of the lines.
</p>
<div class="org-src-container">
<pre class="src src-sh">cat /etc/acpi/events/lidbtn
</pre>
</div>
<pre class="example">
# /etc/acpi/events/lidbtn
# Called when the user closes or opens the lid
#event=button[ /]lid
#action=/etc/acpi/lid.sh
</pre>
<p>
To disable this in <b><i>systemd</i></b>, modify <code>/etc/systemd/logind.conf</code>, and
change the key <code>HandleLidSwitch</code> to ignore:
</p>
<pre class="example">
HandleLidSwitch=ignore
</pre>
</div>
</li>
<li>Enable Lid suspend action in systemd<br ><div class="outline-text-5" id="text-3-1-6-2">
<p>
To enable suspend on closing the laptop lid, disable the <b>acpid</b>'s
like mentioned above. Change the key <code>HandleLidSwitch</code> to suspend in
<code>/etc/systemd/logind.conf</code>:
</p>
<pre class="example">
HandleLidSwitch=suspend
