[SOLVED] Touchpad not working in Linux on Lenovo Ideapad 3.15

cowlitzron · 04-22-2021, 08:04 PM

I have a dual boot of Slackware 15.0 and Windows 10 with Ubuntu MATE 20.04 LTS with the latest kernel in the repository on an external hard drive. I am unable to get touchpad working on the Lenovo Ideapad 3.15IIL05 with either Linux. The output I got with xinput on Slackware is:

Code:


	Code:
	Virtual core pointer                    	id=2	[master pointer  (3)]
    Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]

Since the touchpad does not show up in the xintput listing, the driver is probably not loaded. The first thing to do is determine what hardware device you have, there are several manufactures.

I guessing it works under W10, if yes, look there to find out what hardware you have. Synaptis and Elantech are just 2 manufacturers. Once you know what hardeware you have, there may be a driver in either distro you have. Post what you find. Then we can help further.

Internet search revealed some info. First, it is PS/2 device apparently. Second, there are reports passing "i8042.nopnp=1 pci=nocrs" to Ubuntu kernel makes it work.

I was able to get touchpad to work in Ubuntu 20.04 by adding "i8042,nopnp=1 pci=nocrs" to the kernel line. When I put xinput in Ubuntu it gave the following output:

Quote:

Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ MSFT0001:01 04F3:3140 Mouse id=10 [slave pointer (2)]
⎜ ↳ MSFT0001:01 04F3:3140 Touchpad id=11 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ Integrated Camera: Integrated C id=9 [slave keyboard (3)]
↳ Ideapad extra buttons id=12 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)]

When I entered cat /proc/bus/input/devices this is what I got in Ubuntu for the touchpad.

When I looked up the type of touchpad in Windows 10 it is listed as an HID-compliant mouse. The driver version is 10.0.19041.1. The driver provider is Microsoft.

This is no longer important. The first step of methodical troubleshooting is to identify the type of communication. The second step is finding correct driver and the third step is configuring this driver to work with your device. In case of Ubuntu all three steps are done. You can duplicate this in any other Linux distro. Apparently there is driver conflict, SERIO_I8042 kernel driver needs to be disabled.

I was able to get touchpad to work on Slackware 15.0 beta. I enabled all the recommended modules when I made the initrd and I put the same phrase in the kernel line that I have in my Ubuntu MATE 20.04 install. I am running GRUB2 and triple booting Slackware, Ubuntu MATE, and Windows 10. I have Slackware 14.2 on an old HP desktop.

I found out that putting the module "i8042.nopnp=1 pci=nocrs" in the kernel line in /etc/default/grub is essential to get touchpad to work in Slackware 15.0 beta on a 2021 Lenovo Ideapad laptop. I didn't think I would be able to get Slackware 14.2 to work on this laptop. Since I have 8 gigs of RAM, I'm running KDE Plasma 5 for now.

I just got through purchasing a ideapad game 3 Lenovo laptop, and i cannot get the touchpad to work at all. I installed Ubuntu 20 LTS, and it did not work,
I read that if you install 21.X it would work, so I did. . .that failed too.

I am not very good on Linux I read something like this:

i8042.nopnp=1 pci=nocrs Installed in the grub.

Will this work for me? If it does, where do I install it?
I know how to edit the grub, but that is the extent of my knowledge.

Any help would be appreciated.
