Comment 76 for bug 1218973

Running development of 14.04 (beta).

Havin this same issue reported here (ie. after default install, the touchpad and touchscreen both half-work - can click, but no multi-touch, swipe, drag gestures work)

After blacklisting i2c_hid in /etc/modules.d then touchpad works as expected. However, now touchscreen doesn't register anything at all.

Reading this bug report, I see a references to rmi4 driver to fix this...further I see synaptics_i2c_rmi4 driver in kernel/staging - however upon loading can detect no difference in functionality.

Perhaps I need to disable / enable some other kernel module in conjunction with rmi4 to get this to work?
