Comment 8 for bug 1770306

Since filing this bug, I have been successfully using lxdm as a worked around, with lxde

Recently, after I open this bug, I built my own version of

xserver-xorg-input-synaptics

following the instructions here:
https://askubuntu.com/questions/462135/touchpad-issue-jumping-cursor-while-typing-ubuntu-14-04-syndaemon-dont-help

That solved the problem with using the touchpad, but did not affect lightdm.

I have some other programs I built myself, digikam, for example.
I suspect that none of the others are at fault, but I'm not positive.
