** Changed in: linux (Ubuntu)
Status: Confirmed => Triaged
** Description changed:
- This bug report has been produced to help improve the touchpad on a Dell
- Latitude E7440 on Ubuntu 14.04 alpha.
-
From the live usb the touchpad seems less jerky compared to ubuntu 13.10
but is still not as smooth as Windows 7.
+
+ This may be due to how the touchpad is detected as a PS/2 mouse instead of a
more appropriate touchpad driver:

+ [ 4.088881] mousedev: PS/2 mouse device common for all mice
