>Organization:
>Environment:
Dell Precision M4700
>Description:
Apparently ALPS uses a new protocol for their touchpad, which is incompatible with the current one. As such the touchpad is discovered as a glidepoint and not scrolling or other touchpad interaction is possible except moving the mouse cursor and clicking left/right button.
>How-To-Repeat:
Try any touchpad as released by ALPS since mid 2013
>Fix:
the Linux kernel has already an update that implements the newer protocol versions.
