I've just quickly made the following script for python, only tested with python3, on the stock Mate pinebook install.
Not sure if other installs move around the xinput device for the touchpad (else replace the 8 with the right number)
This script disables the touchpad of the pinebook for 0.5 second whenever a key is pressed, any key, including ctrl/shift/alt/mod. So it's not perfect and cannot be use for shift/ctrl+click very effectively yet. But the script could be modified for that.
Note that if you google for the touchpad problem, you will find a lot of mentions for "syndaemon", which doesn't work (and exits without a message) The "synclient" command however will tell you why, because our touchpad isn't showing up as a touchpad but as an emulated mouse.
Hench this hacky script.
And I've just typed this post without a single problem while the script is running. Figured I share this ASAP, as the very sensitive touch pad is at the top of the list of things that people find annoying.
Code: import threading
import time
import os
class TouchpadHack:
def __init__(self):
self.__disabled = False
self.__condition = threading.Condition()
self.__disabled_until_time = time.monotonic()
threading.Thread(target=self.timeoutThread).start()
def timeoutThread(self):
while True:
with self.__condition:
self.__condition.wait()
os.system("xinput disable 8")
print("disable")
while time.monotonic() < self.__disabled_until_time:
time.sleep(self.__disabled_until_time - time.monotonic())
os.system("xinput enable 8")
print("enable")
def inputReadThread(self):
f = open("/dev/input/event2", "rb")
while True:
# We read events here from the keyboard and then just ignore them.
# The only thing we care about is that an event happens.
event = f.read(100)
with self.__condition:
self.__condition.notify()
self.__disabled_until_time = time.monotonic() + 0.5
TouchpadHack().inputReadThread()
Will make sure to try it out first thing tomorrow and relay feedback.
With the stuff I had laying around from a different project, I enhanced it a bit, it's a bit more complex now, but it should allow shift/ctrl/alt + click now. And be better protected against different order of hardware initialization.

This is really great!!!
I'm able to type without triggering nearly as many stray clicks now.
Thank you!
If you get an error about time.monotonic(), run it with python3 instead of python.
Could be nice to set up a github repo

You would need to run in in your X session, so most likely a proper file in ~/.config/autostart would do it. But I haven't looked into those details yet.

Was the first thing I did - didn't work however. Perhaps I did something wrong.
Running it in a terminal for now, look's good! Will be testing it some more! Thanks!

I made a wrapper shell script that just starts it with
Code: sudo python3 PATH/touchpadsleep.py
(my user account has NOPASSWD in sudoers)
and added that shell script in
System>Preferences>Personal>Startup

Ah. Yes, I tried that too - but didn't think of setting no password for my account ... Thanks for sharing this, although I still would like to keep my password for a variety or reasons.
