** Tags added: apport-collected focal
** 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. 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.
