After upgrading Ubuntu 14.04 -> 14.10 -> 15.04, the Synaptics Touchpad no longer works properly. In 14.04 it was fine, in 14.10 it did not work at all, but in 15.04 it works minimally in that I can do everything except scroll.
The Ubuntu help page says:
Basic Configuration with a Graphical Interface
Ubuntu provides basic configuration of your touchpad options in System -> Preferences -> Mouse, under the Touchpad tab.
Try the touchpad after unchecking the Enable mouse clicks with
touchpad check box.
Check operation after Enable horizontal scrolling is checked. This may
not have been the default setting.
However, when I open the system configuration tool and select, "Mouse and Touchpad" (I assume that is what System -> Preferences -> Touchpad is referring to), these options don't exist.
If I try to use synclient, I get:
"Couldn't find synaptics properties. No synaptics driver loaded?"
Is there anything I can do to get scrolling working?
