Changing dm from lightdm to gdm3 has stopped the crashes for me.

Title:
[Lenovo ThinkPad X230] Input freeze, kernel crash in
input_handle_event
Status in linux package in Ubuntu:
Confirmed
Bug description:
Description: Ubuntu 20.04.1 LTS
Release: 20.04
xorg:
Installed: 1:7.7+19ubuntu14
Candidate: 1:7.7+19ubuntu14
Version table:
*** 1:7.7+19ubuntu14 500

I think the problem arises from use of a USB switch. However it does
not necessarily happen when engaging or disengaging USB hub. Inbuilt
trackpad allows use of cursor during freeze, but not usb attatched
mouse. aside from that nothing gets a response on the display.
Using a Thinkpad X230
kern.log includes crash
