Touchpad not detected in Kali Linux

Question

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?

Answer 1

SOLVED! Woot!

rmmod i2c_designware_platform
rmmod i2c_designware_core

add the following into a modprobe conf file.

blacklist i2c_designware_platform
blacklist i2c_designware_core

Fixed!

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

Answer 3

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.
