Running a Dell 3147 11 inch 2 in 1 with Kali installed on the ssd, it doesn't detect the touchpad. I looked under xinput and it doesn't show up.
I've tried this: https://wiki.debian.org/SynapticsTouchpad too.
Anyone have any thoughts on this?

You can do it by some changes during boot in grub. Do it as follows:
sudo -H gedit /etc/default/grub
Locate the line
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" // or may be only ="quiet"
edit it so that it looks like the following
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nopnp"
Save and run this command in terminal:
Run the following commands in terminal:
echo "blacklist i2c_hid" | sudo tee /etc/modprobe.d/i2c-hid.conf sudo depmod -a sudo update-initramfs -u echo "synaptics_i2c" | sudo tee -a /etc/modules
Another possible solution to help (especially for non-DELL users) is to disable the ACPI option (https://www.kernel.org/doc/html/v4.15/admin-guide/kernel-parameters.html) by adding acpi=off to the kernel boot options.
Touchpad would work after that but since ACPI is used for hardware acceleration you will probably experience some higher CPU usage.
