Are you having a problem with your Ubuntu laptop where your mouse cursor jumps everywhere while you're trying to type? If so, create a script called 'fixtouchpad', put it in ~/bin and make it exectuable.
Inside the file, put:
#!/usr/bin/env bash
pkill syndaemon
syndaemon -i 1 -KRd
Save it. Done.
On startup, you can run:
# fixtouchpad
And then the palm detection problem is now fixed. Mostly. Try it and let me know if you have any problems with it.
