Wacom/ stylus is recognized correctly by xsetwacom, xinput, lshw and lsusb, but not from wacom / stylus in gnome settings. When you extract the stylus it causes the Thinkpad to hang, and it needs a hard reboot. The only solution is to install 5.8.0-44 and completely purge 5.8.0-45. PS: This kind of stuff should not be happening on a production LTS release on machines from a certified supplier. May I recommend making sure you update the kernel only when the entire existing ecosystem is supported? We are talking top of the range machines that can come with Ubuntu pre-installed. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27.16 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: kt529 1144 F.... pulseaudio CasperMD5CheckResult: skip DistroRelease: Ubuntu 20.04 InstallationDate: Installed on 2021-03-05 (17 days ago) InstallationMedia: Ubuntu 20.04.2.0 LTS "Focal Fossa" - Release amd64 (20210209.1) MachineType: LENOVO 20JES4QU00 Package: linux (not installed) ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-5.8.0-44-generic root=UUID=e846a5b7-eb85-4156-9684-7602fe787c20 ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 5.8.0-44.50~20.04.1-generic 5.8.18 PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: No PulseAudio daemon running, or not running as session daemon.
