Touchpad re-enabled on screen lock

[tim-connolly]

Describe the issue
I use the extension to disable the touchpad, while keeping the trackpoint active. When the screen is locked (either manually or automatically after inactivity) the touchpad is enabled. I have to use the extension to disable the touchpad again after unlocking the screen.

---

Expected behavior
The touchpad should remain disabled through the lock and unlocking process.

---

Steps to reproduce the behavior

1. Click on touchpad indicator.
2. Disable touchpad.
3. Verify the cursor cannot be moved using the touchpad.
4. Lock the screen.
5. The touchpad can now be used to move the cursor on the lock screen.

Just to be clear, do you mean that after logging out and logging back in, the touchpad becomes enabled?
Note that the extension can not maintain state on the lock screen.

[tim-connolly]

The scope of the issue was intended to be just the screen lock and unlock cycle.

I have my screen set to lock after 10 minutes of idle time. It is just a bit annoying having to remember to disable the touchpad again each time I unlock the screen.

ubuntu 20.04, I don't have this problem with touchpad, but have this problem with trackpoint

[tim-connolly]

Would it be possible to write the state to a file when the screen is locked, then check that file and restore the state when the screen is unlocked?
