This is a guide for installing / configuring a NextWindow Touchscreen on Ubuntu 18.04.
It is completely based on the work done by Daniel Newton / djp (https://launchpad.net/nwfermi/). The driver consists of a GPL'd kernel part and a proprietary / closed source user space daemon, without this daemon it will not work.
Compared to the latest release this version has following enhancements:
- Fix driver compilation for recent kernels, basically it replaces every err() call with pr_err() as err() macro was removed from usb.h back in 2012
- Fix startup of user space deamon via udev/systemd implementation as you cannot launch 32 bit applications on 64 bits OSes via udev (blocked via seccomp in systemd-udevd)
- Xorg config example
Validated on a Dell SX2210TB, indentified as "1926:0064 NextWindow 1950 HID Touchscreen" by lsusb. Confirmed to be working by user devkicks on a VAIO All in one VPCL11M1E, identified as "1926:0065 NextWindow 1950 HID Touchscreen" (See issue #1)

# cd /usr/src/nwfermi-0.6.5.0/
# patch -p1 < nw-fermi.c.patch
- Make module
# dkms build nwfermi/0.6.5.0
- Install module
# dkms install nwfermi/0.6.5.0
- Copy daemon from deb to /usr/sbin
# cp nwfermi/usr/sbin/nwfermi_daemon /usr/sbin
- Install udev rules from this git repo
# cp etc/udev/rules.d/40-nw-fermi.rules /etc/udev/rules.d/
- Install systemd service file from this git repo
# cp etc/systemd/system/nwfermi@.service /etc/systemd/system/
- Reload systemd
# systemctl daemon-reload

- Extract and compile
# chmod +x autogen.sh ; ./autogen.sh
# make
# make install
- Install module
# cp /usr/local/lib/xorg/modules/input/nextwindow_drv.* /usr/lib/xorg/modules/input/
- Copy Xorg config from this git repo
# cp etc/X11/xorg.conf.d/10-nwfermi.conf /etc/X11/xorg.conf.d/
To be able to read the input device your local user should be part of the input group. Optionally, you should/can add the gdm user to this group as well
# usermod -a -G input gdm
# usermod -a -G input your_username
Reboot and everything should work! Enjoy.
