Fujitsu Touchscreen Driver
For Fujitsu notebooks with serial (not USB!) touchscreens e.g. Lifebook P1610.
Installation
These instructions illustrate setting up the driver on Ubuntu 15.10. The process should be similar on other distributions, though packages and package managers might differ.
Install packages for compiling:
$ apt-get install build-essential pkg-config xserver-xorg-dev
Download, compile, install:
$ git clone https://github.com/okias/xf86-input-fujitouch.git
$ cd xf86-input-fujitouch
$ ./configure --prefix=/usr
$ make && make install
The driver should now be available in /usr/lib/xorg/modules/input.
Usage
Now we want to get X11 to use the driver.
Search for the touchscreen's serial port:
$ cat /var/log/Xorg.0.log | grep ttyS
[ 35.055] (II) config/udev: Adding input device Serial Wacom Tablet FUJ02e6 (/dev/ttyS4)
[ 35.060] (**) Option "Device" "/dev/ttyS4"
Hide/remove the default X11 Wacom driver (which does not work anyway). You can do so by renaming the module:
$ cd /usr/lib/xorg/modules/input
$ mv wacom_drv.so disabled-wacom_drv.so
Add the config file from Issue #4 to X11 to set up the new driver. Remember to change the serial port:
$ mkdir /etc/X11/xorg.conf.d
$ vim /etc/X11/xorg.conf.d/ts.conf
// Content of /etc/X11/xorg.conf.d/ts.conf:

Reboot and see if the touchscreen responds.
If it does not, debug with information from /var/log/Xorg.0.log.
