Configuring the Touch screen for X200T

One of the first things you would like to try on a Tablet PC would be the touch Screen. Having it working on the Lenovo X200T is as easy as:

Install the Linux Wacom drivers. On Arch, you can find it on AUR.
Configure the X.Org server to use it. I post my xorg.conf file as an example:

Section "ServerLayout" Identifier "X.org Configured" Screen "Screen0" InputDevice "Mouse0" "CorePointer" InputDevice "Keyboard0" "CoreKeyboard" InputDevice "stylus" "SendCoreEvents" InputDevice "eraser" "SendCoreEvents" InputDevice "touch" "SendCoreEvents" # Only a few TabletPCs support this typeEndSection
