I have been stress-testing bionic to try and reproduce this crash;
* Changing keyboard layouts
* Changing USB keyboards
* Hotplugging monitors
and nothing I try is able to reproduce this crash or any crash. And I
can't just backport the existing patch for this bug to bionic blindly
because it doesn't merge (comment #10). It would need to be rewritten
from scratch by someone who can also reproduce and verify the bug.
hn23: Please follow the instructions in comment #14. Hopefully that will
help somewhat.
And if anyone else has any tips on how to reproduce what they think is
this bug on Ubuntu 18.04 then please add a comment below.
