[Kernel-packages] [Bug 1923515] Re: [Dell XPS 15 9500] New touchpad detected as "PS/2 Logitech Wheel Mouse"

[Kernel-packages] [Bug 1923515] Re: [Dell XPS 15 9500] New touchpad detected as "PS/2 Logitech Wheel Mouse"
I wanted to hold off until I was sure, but I've confirmed this was a (second) hardware problem. Dell replaced my laptop's touchpad a second time yesterday, and after deleting the device in Windows 10 and refreshing, the OS detected the new touchpad fine. I reinstalled Ubuntu yesterday and it's also working fine, with scrolling etc. functioning as normal. So basically, Dell gave me a laptop with a "broken hardware" touchpad and improbably replaced it with a "bad firmware" touchpad. I appreciate all the help with this issue, and I'll mark this bug resolved, and update the other bugs. Some takeaways: 1. Try other kernels / distros. 2. Try Windows (if available). Dual-boot would have been super handy in this case, even if the Windows installation is for break-glass emergencies. 3. Dell only replaces broken hardware with the same model as the original, so inconsistent hardware detection probably means bad hardware. ** Changed in: linux (Ubuntu) Assignee: (unassigned) => Ed Holden (edholden) -- 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/1923515 Title: [Dell XPS 15 9500] New touchpad detected as "PS/2 Logitech Wheel Mouse" Status in linux package in Ubuntu: Incomplete Bug description: I've been using Ubuntu 20.04 on a Dell XPS 15 9550.

[Kernel-packages] [Bug 1923515] Re: [Dell XPS 15 9500] New touchpad detected as "PS/2 Logitech Wheel Mouse"
Yes, I've been working on installing Windows, and also speaking with Dell, whose support techs say a replacement touchpad should have been the exact same model as the original (except not with a hardware defect). I wanted to make sure they'd support the laptop, which came with Windows, as well as see what device Windows detects. Interestingly, Windows 10 has basically the same issue as Linux! I sees a device called "I2C HID device" that has problems, and in that device's status are the messages "The device cannot start (Code 10)" and "A request for the HID descriptor failed." There's also a pointing device called "PS/2 compatible Mouse" that is ... definitely not a PS/2 mouse. So, I think Windows agrees with Linux and this might not be a kernel issue after all. No amount of Dell Windows driver updates or Windows updates resolves it, and a Dell tech spent a long time remote controlling and testing with me. It looks like Dell replaced a piece of bad touchpad hardware that had good firmware, with a piece of good touchpad hardware that had bad firmware. I'm getting a *second* replacement touchpad in about a week. I can update this bug after the new one is installed and confirmed working, and I reinstall Linux. -- 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/1923515 Title: [Dell XPS 15 9500] New touchpad detected as "PS/2 Logitech Wheel Mouse" Status in linux package in Ubuntu: Incomplete Bug description: I've been using Ubuntu 20.04 on a Dell XPS 15 9550.

[Kernel-packages] [Bug 1923515] Re: [Dell XPS 15 9500] New touchpad detected as "PS/2 Logitech Wheel Mouse"
Possible to test Windows?
