Being told about an error is not a bug. But if you do have a crash file then you can follow these instructions to turn it into a bug report: https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment
Alternatively, your machine may have automatically reported the crash already. In that case please look at https://errors.ubuntu.com/user/ID where ID is the contents of your /var/lib/whoopsie/whoopsie-id file. Give it a few seconds to load the page. If you find any recent links on that page then please share them here. ** Package changed: xorg (Ubuntu) => ubuntu ** Changed in: ubuntu Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1776594 Title: getting system error popup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1776594/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
