After solving problem with touchscreen described in another thread,

http://en.community.dell.com/techcenter/os-applications/f/4613/p/19540194/20503049.aspx#20503049

now the touchPAD isn't working well for scrolling. Buttons & pointing work, but when I try to set scroll bar behavior in system settings or with unity tweak, don't get full touchpad controls (like I do in 12.04). Is there another driver I need for the touchpad (now that I got the touchscreen working).

Thanks for any clues.
