test the script: ``` a. Don't put your finger on the touchpad b. Open a terminal window and run `sudo dmesg -W` c. In another terminal, "cd /sys/class/gpio/gpio386" e. "echo out > direction" and see if the following dmesg output will keeping popping out in the previous terminal window
``` [ 138.233653] i2c_hid i2c-MSFT0001:00: i2c_hid_get_input: IRQ triggered but there's no data ``` d. Then "echo in > direction", now the dmesg output in step 3 should stop popping out. f. Repeat step e-d for around 5 times ``` window 1: ``` [ra@localhost ~]$ su Password: [root@localhost ra]# cd /sys/class/gpio/ [root@localhost gpio]# echo 386 > export [root@localhost gpio]# ls export gpio386 gpiochip256 unexport [root@localhost gpio]# cd /sys/class/gpio/gpio386 [root@localhost gpio386]# echo out > direction [root@localhost gpio386]# echo in > direction [root@localhost gpio386]# echo out > direction [root@localhost gpio386]# echo in > direction [root@localhost gpio386]# echo out > direction [root@localhost gpio386]# echo in > direction [root@localhost gpio386]# echo out > direction [root@localhost gpio386]# echo in > direction [root@localhost gpio386]# echo out > direction [root@localhost gpio386]# echo in > direction [root@localhost gpio386]# ``` window 2: ``` [ra@localhost ~]$ sudo dmesg -W [ 191.989163] i2c_hid i2c-MSFT0001:00: i2c_hid_get_input: IRQ triggered but there's no data ``` it's only out one line on first it run echo out > direction. during test ,no figure touch the touchpad. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-libinput in 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 _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
