ELANTECH - Touchpad Palm Resist

English Hardware
#1

The guys from ELANTECH supplied the drivers to WIndoze but not to Linux, I think.

Occasional touch by palm on touchpad disrupts typing. What can I do?

This thread for synaptics touchpad suggested

Will that work for ELANTECH too?

I don’t know if it will work, but why not try. If you have KDE installed, then “synaptiks” is probably already there.

I set it to disable the touchpad if there is a mouse plugged in. That avoids the problem you are having.

#3

Used Touchpad - KDE Control Module.
Could install synaptiks as it required kde4 and it couldn’t be provided as I’m on KDE5 and gsynaptics was already installed and didn’t had enough functionality, ultimately had to install kcm-touchpad5

Note: Palm detection also requires Hardware / Firmware support from the touchpad. Which I thinkso is not there.

I also don’t know whether it should be checked or not.
