Public bug reported:
Touchpad for the Dell Inspiron 7537 cannot move objects on desktop
without troubles. I have tried this under the GNOME, KDE, and Unity
desktops and they all show the problem so it is not there. I have the
latest (A10) BIOS from Dell and am running a fully up-to-date Ubuntu
14.04.
It is the intergrated touchpad (well, clickpad since there are no
distinct buttons) for one of Dell's most popular laptops. A web search
finds other people having similar trouble.
You cannot move windows around because they jump around wildly making
the device practically unusable. It requires using an external mouse
with the laptop.
Problem is almost surely with the Synaptic driver for the touchpad.
Here's the output of "lspci" if that helps:
