Title says it all really? Is there an easy command line to do this?
You could have a look at this https://wiki.archlinux.org/index.php/Touchpad_Synaptics#Disable_trackpad_while_typing
It also depends on what DE your using.
No DE, open box :)
The wiki link should be your answer then, its the commands to set the palm detection stuff.
Yes, it worked! thank you!
