Hi!

Touchpad Lenovo Ideapad Gaming 3 (15ARH05 Type 82EY) doesn't work at all:

I: Bus=0018 Vendor=04f3 Product=3140 Version=0100
N: Name="MSFT0001:00 04F3:3140 Mouse"
P: Phys=i2c-MSFT0001:00

B: ABS=2e0800000000003
B: MSC=20 

I tried and tried many ideas and only this works.
That fixes the problem and I can use my touchpad:

1)I write this script:
cat /usr/local/bin/touchpadfix
#!/bin/bash
cd /sys/class/gpio/
echo 386 > export
cd gpio386
echo out > direction

and

chmod +x /usr/local/bin/touchpadfix

2)I made a new service:
/etc/systemd/system/touchpadfix.service 
[Unit]
Description=Fix touchpad issue by binding correct driver

[Service]
ExecStart=/usr/local/bin/touchpadfix
Type=oneshot
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

and

systemctl daemon-reload
systemctl enable --now touchpadfix.service

I hope this idea will be usefull

Thanks

Thank you for the report, and all your work to find a solution.
FWIW "Lenovo IdeaPad Gaming 3-15ARH05" is the model. An ideal user case for including in testing the pre-release ISOs...

Can you please attach the file /var/log/Xorg.0.log

please provide full dmesg or journal from boot, as grepping for stuff leaves out several important bits

Assigning this to the kernel/drivers people; tmb already involved.

I wondered whether the Xorg log (just Mouse-Touchpad part) from the NON-working touchpad system would make a useful comparison. Leave to others to ask if necessary.

Hi!

Touchpad Lenovo Ideapad Gaming 3-15ARH05 works by kernel-5.12-xxx.

My script touchpadfix had problems from kernel-desktop-5.10.43-1.mga8-1-1.mga8.
So I used core-backports and did urpmi-auto-update.

Now:

# uname -a
