Linuxwacom's input-wacom- the USB kernel module/driver

Xorg's xf86-input-wacom - the X driver
xf86-input-wacom 0.19.0 released (1-3-13). Adds support for the 0x4001, TabletPC sensor with 10-finger touch. Multiple bug fixes.
Just substitute the current version numbers in the HOW TO's instructions.
Warning for Precise:
Ubuntu has customized their input ABI (X Server 1.11 and 1.12 hybrid) and it is no longer compatible with some upstream packages including xf86-input-wacom. Consequently if you compile xf86-input-wacom in Precise it will cause your system to not start if you have your BambooPT plugged in, or to crash/freeze if you plug it in after it has started. You need to patch xf86-input-wacom to make it compatible.
Instructions for xf86-input-wacom in Precise:
Follow the HOW TO as normal until you get to the ./configure --prefix=/usr or ./autogen.sh --prefix=/usr command. Stop there and don't enter it. If using xf86-input-wacom-0.17.0 or earlier download the build_against_frankenserver.patch attached to post #1034 onto your Desktop. If using xf86-input-wacom-0.18.0 or later download the build_against_frankenserver_for0.18.patch attached to post #1398 above onto your Desktop. Rename it from build_against_frankenserver.patch.txt to build_against_frankenserver.patch or build_against_frankenserver_for0.18.patch. Apply the patch with a -p1 strip:
You should see this output:
patch -p1 < ~/Desktop/build_against_frankenserver.patch
(or for xf86-input-wacom-0.18.0 and later)
patch -p1 < ~/Desktop/build_against_frankenserver_for0.18.patch
After you see it you can proceed with ./configure --prefix=/usr or ./autogen.sh --prefix=/usr and the rest of the commands.
