I upgraded to 16.10 a few days ago and had a total freeze on the system; unresponsive cursor, couldn't exit X and had to force shutdown vi the power button. After that I have been experiencing problems with a dual display setup which don't allow arranging them. Instead the system logs out.

Furthermore the touchpad settings are not visible any longer and I cannot change the scrolling method to natural scrolling. The dconf editor (under org> gnome> desktop> peripherals> touchpad) states that the natural-scroll setting is enabled though. The scenario is similar to this. I've got xserver-xorg-input-synaptics installed instead of libinput.

Ubuntu Gnome 16.10 running on a 13" MacBook 5,1 (2009)

I found the problem being that both libinput and the synaptics drivers were present. I've deleted synaptics driver as it's legacy and got libinput instead:

sudo apt install libinput-bin & xserver-xorg-input-libinput

which leaves me with quite an empty mouse/trackpad pane in system settings. The only options there are the choices of either using the left or right button for the primary click.

Current mouse/trackpad settings can be set with gpointing-device-settings or in /usr/share/X11/xorg.conf.d/60-libinput.conf.

gpointing device settings

As for the problem with the display, a reinstall of the nVidia driver

sudo apt install --reinstall nvidia-340

and a reboot made the screens work together again.
