View source for Installing Ubuntu 11.10 (Oineric Ocelot) on a ThinkPad T410

This article describes the installation of '''Ubuntu 11.10''' (64 bit) on a Thinkpad T410 type 2537-9UG (NVIDIA NVS 3100M).
''This guide assumes that NVIDIA Optimus is disabled in BIOS (Graphics set to "discrete")!''

== Hardware Support Details ==

=== Works out-of-the-box ===
* Ethernet
* Audio
* DVD burner
* Card reader
* Webcam
* WLAN
* Bluetooth
* DisplayPort (tested with HDMI-TV)

=== Works with additional configuration ===
* Display brightness with NVIDIA
* HDAPS
* Docking station ''(Details soon)''


=== Untested ===
* FireWire
* Fingerprint
* NVIDIA Optimus

The remaining devices are currently not tested.
 
=== Display brightness with NVIDIA ===

Use the following parameter in the "Device"-section of '''/etc/X11/xorg.conf''':
<pre>Option "RegistryDwords" "EnableBrightnessControl=1"</pre>

=== HDAPS (Hard Drive Active Protection System) ===

You need the ThinkPad SMAPI and the hdaps-daemon, install them by following command:

<pre>sudo apt-get install tp-smapi-dkms hdapsd</pre>

Edit '''/etc/default/hdapsd''' with root privileges:

<pre>
START=yes         # hdaps should be started automatically
DISK=sda          # normally sda should fit 
SENSITIVITY=15    # higher values mean lesser sensitivity 
FORCEENABLE="no"  # force hdaps, not needed
OPTIONS=""        # additional options, not needed
</pre>

Restart the daemon:

<pre>
sudo /etc/init.d/hdapsd restart
</pre>

Testing (stop daemon and start in foreground):

<pre>
sudo /etc/init.d/hdapsd stop
</pre>

<pre>
sudo hdapsd -d sda -s 15
</pre>

If you shake your T410 gently the output should look like:

<pre>
sven@T410:~$ sudo hdapsd -d sda -s 15
Tue Nov 15 13:25:25 2011: Starting hdapsd
Tue Nov 15 13:25:25 2011: Selected interface: HDAPS
Tue Nov 15 13:25:25 2011: Selected HDAPS input device: /dev/input/event9
Tue Nov 15 13:25:28 2011: parking
Tue Nov 15 13:25:29 2011: un-parking
</pre>

If test was succesful start daemon again:

<pre>
sudo /etc/init.d/hdapsd start
</pre>

=== Docking station (tested with Lenovo Mini Dock Series 3) ===

* Per hardware design the DisplayPort and DVI connector of the Mini Dock Series 3 are only usable with NVIDIA NVS 3100M
* If you want your boot screen on an external display in T410 BIOS set Graphics to "discrete" and boot screen to what you desire
* My T410 always showed the login screen on the internal LCD, for a workaround see "Workarounds" section
* To avoid conflicts with Unity I suggest using two different xorg.conf (see "Workarounds" section)

=== Workarounds ===

For setting various boot-time options I use Ubuntu's '''/etc/rc.local''' file (paste them '''before''' "exit 0" line!):

<pre>

# T410 Workarounds

# choose xorg.conf
DOCKED="`lsusb | grep "Lenovo ThinkPad Mini Dock Plus Series 3" | wc -l`"
if [ $DOCKED -eq "1" ]
        then
                cp /etc/X11/xorg.conf-docking /etc/X11/xorg.conf
        else
                cp /etc/X11/xorg.conf-nodocking /etc/X11/xorg.conf
fi

# enable/disable bluetooth at startup
echo 0 > /sys/devices/platform/thinkpad_acpi/bluetooth_enable

# enable/disable wwan at startup
echo 0 > /sys/devices/platform/thinkpad_acpi/wwan_enable

</pre>

The above file allows you to specify a xorg.conf for docked-state of your T410 and for undocked state. If you have trouble creating them use the "NVIDIA X Server Settings Tool" shipped with the NVIDIA driver.

You can disable or enable bluetooth and wwan by echoing 0/1 to the interfaces.

'''Technical explanation:'''

* For unknown reasons in 11.10 neither ''/sys/devices/platform/dock.0/'' nor ''/sys/devices/platform/dock.1/'' refers to the attached "Lenovo Mini Dock Series 3", so I had to use the lsusb-approach to check for presence of the docking station. Worked fine for me.
