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?

rmmod i2c_designware_platform
rmmod i2c_designware_core

add the following into a modprobe conf file.

blacklist i2c_designware_platform
blacklist i2c_designware_core


  • It would be nice (and a better answer) if you said how this solved your issue.

You can do it by some changes during boot in grub. Do it as follows:

  1. Run sudo -H gedit /etc/default/grub

  2. 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"
  3. Save and run this command in terminal: sudo update-grub

  4. 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
  5. Reboot

Thanks to pilot6 from askubuntu for the correct solution:



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.
