Hi,
some minor questions:
1. Is this a new issue ? (e.g. after a recent update ?)
2. Does this happen also with a manual start ?

Betreff: Xorg core dump Device or resource busy
Hi All,
I'm running Ubuntu 20.04 and periodically Xorg failing with core dump right
after boot. I'm using a multiseat setup with 2 wireless keyboards and 2
wireless mouses connected. It looks like frequent mouse polling caused Xorg to
slow down. But I have updated the polling interval like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbhid.mousepoll=4"
update-grub
But still, Xorg is failing with core dump and sometimes freezing.
This is from Xorg.0.log
