Sorry that it is taking so long to fix this. There have been several attempts at fixing this upstream already, but all of them had to be reverted/dropped because they were causing issues on other laptop models.
The latest attempt at fixing this is here: https://lore.kernel.org/linux-pci/20220512202511.34197-2-hdego...@redhat.com/ And this patch, or something close to it will hopefully go upstream soon. Perhaps one of the Ubuntu kernel devs can provide a test kernel with this patch for Ubuntu users with this problem to test? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1921649 Title: 'Ideapad S145 Touchpad' not working at all.
