[Bug 1465479] [NEW] Palm detection does not work on synaptics touchpad

 

Public bug reported:

I am unable to type properly on the Dell xps 13 2015 model (Ubuntu
vivid)  without first disabling "click to touch" in settings. The cursor
jumps to wherever the mouse pointer is and starts typing from that
point. Currently I cant type even three words straight without the third
word getting inserted somewhere in between the earlier words or entire
paragraphs getting deleted because of auto-selection...

I tried setting  PalmMinZ=100 in /etc/X11/xorg.conf.d/20-synaptics.conf
but no luck after a reboot.  According to this page :
http://xps13-9333.appspot.com/#touchpad   this was fixed in kernel 3.16
but I am on kernel 3.19 and the problem still exists.
