This is a guide for installing / configuring a NextWindow Touchscreen on Ubuntu 22.04.
The files in this repo will install nwfermi 0.7.0.1.
It is based on the files provided by HP as SUSE drivers for the "HP Compaq Elite 8300 All-in-One Desktop PC". HP Support Link | Direct Link
The HP driver has not been updated anymore since 2013, I've made following enhancements:
- Fix driver compilation (fix work_struct/delayed_work structs usage, fix some minor compiler warnings)
- 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
For models 1926:1846 and 1926:1878 you need to install the additional "fwprod" daemon. Its usage is unclear but seems to work according to #4. See additional steps as required outlined below.
- The kernel driver has been released under a GPL license by NextWindow
- The user space daemons and xf86-input-nextwindow Xorg module are copyrighted by NextWindow and released under following license
apt-get install dkms build-essential autoconf xutils-dev libtool xserver-xorg-dev libc6-i386 pkg-config evtest
Install libudev1 and symlink it to libudev0 (no longer available as i386)
apt-get install libudev1:i386
ln -s /usr/lib/i386-linux-gnu/libudev.so.1 /usr/lib/i386-linux-gnu/libudev.so.0
# wget https://github.com/glorang/nwfermi/archive/refs/heads/master.zip
# unzip master.zip
# cd nwfermi-master
All following chapters assume you are executing the steps as outlined from within the nwfermi-master folder.
- Remove nwfermi/0.6.5.0 if installed
# dkms unbuild nwfermi/0.6.5.0 --all
- Install nwfermi source to /usr/src
# cp -p -r usr/src/nwfermi-0.7.0.1 /usr/src
- Build nwfermi/0.7.0.1
# dkms build nwfermi/0.7.0.1
- Install module
# dkms install nwfermi/0.7.0.1
- Copy Xorg config
# cp etc/X11/xorg.conf.d/10-nwfermi.conf /etc/X11/xorg.conf.d/
- Copy nwfermi_daemon to /usr/sbin
# cp 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 files from this git repo
# cp etc/systemd/system/[email protected] /etc/systemd/system/
- Reload systemd
# systemctl daemon-reload
- Copy fwprod to /usr/sbin
# cp usr/sbin/fwprod /usr/sbin
- Install systemd service files from this git repo
# cp etc/systemd/system/fwprod-1926-1846.service /etc/systemd/system/
# cp etc/systemd/system/fwprod-1926-1878.service /etc/systemd/system/
- Reload systemd
# systemctl daemon-reload
# cd usr/src/xf86-input-nextwindow-0.3.4
# 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/
Edit /etc/gdm3/custom.conf and set WaylandEnable=false in the [daemon] section.
To be able to read the input device your local user must be part of the input group. You should 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.
Use following steps for some general debugging hints:
- Run
lsusband check if your model (1926:XXXX) is supported by the driver nw-fermi.c, line #49 and onwards - Check if kernel module is loaded:
lsmod |grep -i fermi - Enter
strings /dev/nwfermi1(or nwfermi2) it should produce garbage text output when you touch the screen - Start nwfermi daemon manually in foreground
/usr/sbin/nwfermi_daemon /instanceId 1, expected output:
# /usr/sbin/nwfermi_daemon /instanceid 1
StartThreads

Run evtest and select "Nextwindow Fermi Touchscreen" and touch your screen, you should see it generate events. Expected output:
