7” Touchscreen Display + rPi 3 + Right Click (Long Click)?

Question

Hello!

The screen works really wll with my Pi3, except I have not been able to setup right-clicking or long-clicking.

I'm running Jessie and the instructions for the Wheezy do not work on Jessie.

Has anyone been able to setup the screen for right-click or long-click?

Thanks.

Everyone who is having problems with Jessie and the debug message "No valid axis inversion data found".

I think I found a workaround:

# Install packages

sudo apt-get update && sudo apt-get install build-essential libx11-dev libxi-dev x11proto-randr-dev libxrandr-dev libxtst-dev xserver-xorg-input-evdev

# Install twofing

cd ~

wget http://plippo.de/dwl/twofing/twofing-0.1.2.tar.gz

tar -xvzf twofing-0.1.2.tar.gz

cd twofing-0.1.2

make && sudo make install

# create a new rule-file

sudo nano /etc/udev/rules.d/70-touchscreen-raspberrypi.rules

# add the following line

KERNEL=="event*",ATTRS{name}=="FT5406 memory based driver",SYMLINK+="twofingtouch",MODE="0440"

# modify X11 config

sudo nano /usr/share/X11/xorg.conf.d/40-libinput.conf

# add the following lines at the end of the file

Section "InputClass"

Identifier "calibration"

Driver "evdev"

MatchProduct "FT5406 memory based driver"

Option "EmulateThirdButton" "1"

Option "EmulateThirdButtonTimeout" "750"

Option "EmulateThirdButtonMoveThreshold" "30"

EndSection

# Reboot your device

sudo reboot

# Check if twofing is working

twofing --debug

# Add twofing to autostart

nano ~/.config/lxsession/LXDE-pi/autostart

# add the line at the end

@/usr/bin/twofing

# Cleanup

cd ~

rm -rf ~/twofing-0.1.2
