Touchpad not work

Post by Leila »

Hi, i install Mint 20 in my new computer Lenovo and the Touchpad not work. I tried the following thing and not solve the problem:

- change the grub to: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.reset i8042.nomux i8042.nopnp i8042.noloop"
- change the kernal (I have the 5.4.0-48)

if i type: less /proc/bus/input/devices i don't see a touchpad!

Does anyone know how I can solve it?

Thanks, Leila.

Straight from Release Notes:
Touchpad drivers
The default touchpad driver in this edition is "libinput" (provided by the xserver-xorg-input-libinput package).

If you experience problems with it, you can switch to another driver called "synaptics" (provided by the xserver-xorg-input-synaptics package).

To know which driver is used by your input devices, run the following command:
grep -i "Using input driver" /var/log/Xorg.0.log

When both drivers are installed, "synaptics" takes priority.

To switch to the "synaptics" driver, install it with the command:
apt install xserver-xorg-input-synaptics

Then log out and log back in.

To go back to using "libinput", simply remove the "synaptics" driver:
apt remove xserver-xorg-input-synaptics

Then log out and log back in.

Note: You can also try installing the "evdev" driver (provided by the xserver-xorg-input-evdev).

That is unfortunately a common problem with Lenovo laptops, especially if it is a very new one, but if you give us more details about your computer, we will have a better idea if we can be of help. Please give us information about your install by entering this command in a terminal:

Code: Select all

inxi -Fxxxrz
Enclose the results between [code] and [/code] code markers by selecting </> from the mini toolbar above the textbox where you type your reply. This will let us know how Mint sees your hardware.

Also, please let us see the output of xinput -list.
