[Bug 1272624] Re: [Dell Latitude E7440] 14.04 Touchpad not as smooth as Win7

 

The main problem seems to be when I place a second finger close to my
first finger causing the cursor to jump and jerk across the screen
(i.e., disappers and reappears in any other part of the screen).  I have
tried to alter values in synclient to reduce this but I haven't had much
luck.

I've compared the touchpad sensitivity in Win7 and this doesn't happen
there.  As for the touchpad area, the very top and very bottom also are
not respsonsive in Win7 so this is probably not an issue, just something
I picked up on (#7) when searching for clues.
