Thanks for review, actually, it is not a kernel bug, it is because the touchpad report descriptor doesn't config correctly, please refer to the windows document "Device capabilities feature report" part. https://docs.microsoft.com/en-us/windows-hardware/design/component-guidelines/windows-precision-touchpad-required-hid-top-level-collections The touchpad device announce it is a depressible touchpad, which is not, so that the kernel set the INPUT_PROP_BUTTONPAD bit which leads the libinput won't handle the BTN_RIGHT event. I have asked the touchpad vendor, they have no capability to update touchpad firmware on Linux currently. Sorry that I just attach the debdiff for my test ppa, will upload a more official debdiff here. May I know how many release should I do SRU? Bionic, Focal, and Groovy is enough? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1906341 Title: Touchpad button doesn't work on Dell Precision 7550/7750 To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1906341/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
