Today I find something interesting about the GPIO controller. I wonder if the same thing would happen to the ELAN touchpads.
For those who have the ELAN touchpad, could you show me the result of the following experiment with a kernel not having the polling_pin_state_touchpad.patch? ```bash # install hid-tools # If it's not provided by your distribution's package manager, you can install it by pip # sudo pip install hid-tools # run hid-recorder and choose the device having name "MSFT*" $ sudo hid-recorder Available devices: /dev/hidraw0: MSFT0001:00 06CB:7F28 # now open another terminal window # switch to root user sudo su # go to gpio's sysfs cd /sys/class/gpio/ # export the pin used by the touchpad echo 386 > export # now you will see a folder named gpio396 created # change the pin as an output echo out > gpio396/direction # write 1 to the pin echo 1 > gpio386/value ``` Now move your finger on the touchpad. See if your cursor moves now and if there is any output from hid-recorder. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1887190 Title: MSFT Touchpad not working on Lenovo Legion-5 15ARH05 To manage notifications about this bug go to: https://bugs.launchpad.net/pop-os/+bug/1887190/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
