New Laptop and Unresponsive Touchpad

Post by bberkey1 »

Hello,

I've been playing with a new laptop, Lenova Ideapad S145, and after finally getting the wifi realtek drivers installed, the other issue I'm having is a total unresponsiveness of the touch pad. I've searched the forums and have tried a few suggestions, but with no luck yet. I thought perhaps since this is new, the touchpad my not be compatible with any Linux drivers yet? I'm not sure. My wireless mouse works just fine and although I don't plan on using the pad often, it's still nice to have a backup, so I thought I'd ask.

Note: I plan to do another clean install on this computer, as I've been experimenting with a few things and always like to start fresh if I do so. Also, I've already noticed my error in creating such a small swap partition. Not sure how I messed that up, but it is what it is.

Also after check the input list, I'm not sure the touchpad is even recognized. Am I missing it in this list?

Is this still an issue with the 5.8 kernel?

There are some other drivers listed in the "Touchpad drivers" section of the Release Notes for Linux Mint 20 Cinnamon that you can try.

If you know you have an Elan touchpad then maybe the link in this thread
Lenovo V15-IIL Touchpad and WiFi Not Working
to the Ubuntu bug report might have some possible solutions.

No luck with 5.8.

Someone suggested over at Lenovo that certain hardware just isn't supported and it looks like perhaps this might be the case unfortunately. Never used a Lenovo before, but Dell has never had this issue in my prior experience so it's a little frustrating at this point.

What does xinput -list show?

Dell has sold computers with Linux for a while. I don't believe that is the case for Lenovo.

Straight from Linuxmint.com 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).
