Lubuntu 20.04 libc-2.31.so general protection fault

[gregoryo]

Hi everyone,
As per https://discourse.lubuntu.me/t/libc-2-31-so-general-protection-fault-external-monitor/1911 I have a working setup with my Lenovo ThinkPad X1 Carbon gen 7 and Thunderbolt dock 40AF0135AU running Lubuntu 20.04. Initially I connected directly with HDMI cable, but since finding the DisplayLink driver I have now connected DisplayPort through the TB3 dock, and `arandr` shows me a DVI-I device which mostly continues to work.

Sadly it kicks me to login screen sometimes multiple times a day (although not at all today). Coinciding with this is an entry in dmesg, kern.log or syslog `general protection fault ... libc-2.31.so` from either lxqt-globalkeys or Core. It appears to be when the display is busier - Youtube videos, videoconferencing, or switching (with the keyboard) between virtual desktops.

I have compiled hardware information and sample of the errors at https://gist.github.com/gregoryo2014/7946928b64881d0eecaee93bf842cab4

Can I get some help troubleshooting this please? Is it a bug?

Thanks,
Greg.

I found instructions on submitting support requests, and so here is the zip file output of the support tool.

Bump.

Is there anything I can do to get a response to this?
