[Bug 1272624] Re: [Dell Latitude E7440] 14.04 Touchpad not as smooth as Win7
Scott Hosking, the issue you are reporting is an upstream one. Could you
please report this problem through the appropriate channel by following
the instructions _verbatim_ at
https://wiki.ubuntu.com/Bugs/Upstream/kernel ?
Please provide a direct URL to your e-mail to the mailing list once you
have made it so that it may be tracked.
Thank you for your understanding.
** 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:
