Sorry, no.

If it's any clue the mouse and touchpad choice in Settings only has a tab for the mouse but not one for the touchpad

Try:

xinput --set-prop --type=int --format=32 "AlpsPS/2 ALPS GlidePoint" "Synaptics Two-Finger Pressure" 125
xinput --set-prop --type=int --format=32 "AlpsPS/2 ALPS GlidePoint" "Synaptics Two-Finger Width" 0
xinput --set-prop --type=int --format=8 "AlpsPS/2 ALPS GlidePoint" "Synaptics Two-Finger Scrolling" 1 0

Does it jump into life?

Adding GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.reset i8042.nomux i8042.nopnp i8042.noloop" to /etc/default/grub helped me out.

Can you help with this problem?
