Public bug reported: On Ubuntu 20.04.2 when you do a routine update from 5.8.0-44 to 5.8.0-45 it critically breaks wacom / stylus on a ubuntu certified ThinkPad X1 Yoga. 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. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: kernel-bug libinput libwacom ** Description changed: On Ubuntu 20.04.2 when you do a routine update from 5.8.0-44 to 5.8.0-45 it critically breaks wacom / stylus on a ubuntu certified ThinkPad X1 Yoga.
