some minor questions:<br>
1. Is this a new issue ? (e.g. after a recent update ?)<br>

Betreff: Xorg core dump Device or resource busy<br>
<br>
Hi All,<br>
<br>
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:<br>
<br>
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbhid.mousepoll=4"<br>
update-grub<br>
<br>
But still, Xorg is failing with core dump and sometimes freezing.<br>
This is from Xorg.0.log<br>
