[How To] Two finger touch for right click

Sun May 09, 2021 2:08 pm

So I'm using a (formerly windows) tablet now running rpios buster for PC's

The touchscreen works great (as does almost everything on this tablet)

I followed the directions given and got:

pi@raspberry:~ $ twofing --debug
twofing, the two-fingered daemon

Input device name: "Lid Switch"
ERROR: Input device not found in XInput device list!

This is the output of my xinput --list:

pi@raspberry:~ $ xinput --list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ FTSC9999:00 2808:5012 id=14 [slave pointer (2)]
⎜ ↳ HAILUCK CO.,LTD USB KEYBOARD Mouse id=9 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Video Bus id=6 [slave keyboard (3)]
↳ bytcr-rt5640 Headset id=13 [slave keyboard (3)]
↳ gpio-keys id=15 [slave keyboard (3)]
↳ gpio-keys id=16 [slave keyboard (3)]

↳ HAILUCK CO.,LTD USB KEYBOARD id=11 [slave keyboard (3)]
↳ HAILUCK CO.,LTD USB KEYBOARD Wireless Radio Control id=12 [slave keyboard (3)]

This is my /etc/udev/rules.d/70-touchscreen-egalax.rules:

KERNEL=="event*",ATTRS{name}=="FTSC9999 memory based driver",SYMLINK+="twofingtouch",RUN+="/bin/chmod a+r /dev/twofingtouch"

Also tried FTSC9999:00

Does anyone have any suggestions?

This is quite literally the last thing I need to make this tablet fully fuctional
