Scott, if you get chance, also test ElementaryOS. I have just switched from that to Ubuntu and Ubuntu Gnome 14.04 for testing and my touchpad (Lenovo Z500) is also quite jerky. Or rather I suppose I would describe it as a grainy movement. In ElementaryOS it was fine although it is also jerky in 12.04 which ElementaryOS is based upon.
I'm going to try and find out if the Elementary team adding anything else to their distro. Might not help, but if 12.04 is the same..might be worth a shot. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1272624 Title: [Dell Latitude E7440] 14.04 Touchpad not as smooth as Win7 Status in “linux” package in Ubuntu: Incomplete Bug description: This bug report has been produced to help improve the touchpad on a Dell Latitude E7440 on Ubuntu 14.04 alpha.
