@wangjun Thank you for doing this experiment! 1. When the touchpad works by setting pin's direction=out, you could see lots of "no data" message ("IRQ triggered but there's no data") keeping popping up after moving your finger away from the touchpad, am I correct?
2. When pin's direction=out, does only one new "no data" message or multiple ones appear on the screen when you toggle the pin value? -- 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
