Would it be possible for you to do a kernel bisection? First, find the last -rc kernel works and the first -rc kernel doesn’t work from http://kernel.ubuntu.com/~kernel-ppa/mainline/
Then, $ sudo apt build-dep linux $ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git $ cd linux $ git bisect start $ git bisect good $(the working version you found) $ git bisect bad $(the non-working version found) $ make localmodconfig $ make -j`nproc` deb-pkg Install the newly built kernel, then reboot with it. If it still have the same issue, $ git bisect bad Otherwise, $ git bisect good Repeat to "make -j`nproc` deb-pkg" until you find the offending commit. -- 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/1875983 Title: Thinkpad X1 Tablet Gen3 trackpoint and touchpad buttons not working with 5.3.0-51 Status in linux package in Ubuntu: Incomplete Bug description: As per summary, after dist-upgrading a 18.04LTS on the device, the trackpoint and touchpad buttons stopped working.
