SUMMARY

Somewhat related to bug 415364.

I have the "Disable touchpad while typing" option set in KDE. 
However, while typing this touchpad sometimes is still active, and then unintended inputs are made. 

STEPS TO REPRODUCE
1. Select "Disable touchpad while typing" in the KDE config.  
2. Start typing into a document.
3. Pause for a second while thinking of what to type next.

OBSERVED RESULT
Touchpad becomes active and performs unexpected inputs.

EXPECTED RESULT
Touchpad to remain inactive.

ADDITIONAL INFORMATION
There is no tunable options for this "Disable touchpad while typing" setting. I would like to be able to make it more or less sensitive, or set some timeout or something. It is not working as intended, and the unintentional mouse inputs from the touchpad is quite annoying. 

On a side note, the touchpad on this particular notebook is huge, which is nice when the input device is actually being used, but not so nice when typing, as there is no way to avoid touching it.

This feature--and in particular the duration of touchpad disablement--is controlled by the Libinput library as a lower level than us. More generally, it seems like there's a deeper issue with your hardware being too sensitive, or with the palm rejection not working properly. I might suggest reporting *that* instead of the "my touchpad isn't disabled for long enough" issue.

You can do so at https://gitlab.freedesktop.org/libinput/libinput/-/issues.

Thanks!
