# Lenovo ThinkPad T410

The ThinkPad T410 is a laptop with little to no hardware issues.

## Trackpoint

To make the trackpoint able to scroll while holding down the middle button, make a xorg configuration file `/etc/X11/xorg.conf.d/20-trackpoint.conf` with the following contents:

    Section "InputClass"
    	Identifier	"Trackpoint Wheel Emulation"
    	MatchProduct	"TPPS/2 IBM TrackPoint|DualPoint Stick|Synaptics Inc. Composite TouchPad / TrackPoint|ThinkPad USB Keyboard with TrackPoint|USB Trackpoint pointing device|Composite TouchPad / TrackPoint"
    	MatchDevicePath	"/dev/input/event*"
    	Option		"EmulateWheel"		"true"
    	Option		"EmulateWheelButton"	"2"
    	Option		"Emulate3Buttons"	"false"
    	Option		"XAxisMapping"		"6 7"
    	Option		"YAxisMapping"		"4 5"
    EndSection

## Fingerprint reader

The fingerprint reader works, just follow the setup guide in Fprint.

## Graphics

If you happen to have the nvidia graphics card, and you intend to use the properitary driver (packages called 'nvidia' from extra), you may have problems to use the fn keys to adjust the brightness of the backlight. The solution is to make a Xorg configuration file, `/etc/X11/xorg.conf.d/15-nvidia.conf`, with the following contents:

    Section "Device"
      Identifier              "Device0"
      Driver                  "nvidia"
      VendorName              "NVIDIA Corporation"
      Option "RegistryDwords" "EnableBrightnessControl=1"
      Option "NoLogo"         "true"
      Option "Coolbits"       "1"
      Option "TripleBuffer"   "True"
      Option "DPMS" "True"
    EndSection

Where the important part is the option:

    Option "RegistryDwords" "EnableBrightnessControl=1"

This at least works for the graphics card:

    01:00.0 VGA compatible controller: NVIDIA Corporation GT218 [NVS 3100M] (rev a2)

## Modules
