Thank you for taking the time to report this bug and helping to make Ubuntu better. It sounds like some part of the system has crashed. To help us find the cause of the crash please follow these steps:
1. Look in /var/crash for crash files and if found run: ubuntu-bug YOURFILE.crash Then tell us the ID of the newly-created bug. 2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us. 3. If step 2 also failed then apply the workaround from bug 994921, reboot, reproduce the crash, and retry step 1. Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself. ** Package changed: xorg (Ubuntu) => ubuntu-mate-meta (Ubuntu) ** Changed in: ubuntu-mate-meta (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1803992 Title: Lock screen, notifications panel crashes Status in ubuntu-mate-meta package in Ubuntu: Incomplete Bug description: Multiple issues: 1) Lock screen crashes revealing the desktop after sleep/wake 2) Notification panel crashes constantly (with ubuntu-mate) 3) Ability to send report fails for whatever reason Pics attached here: https://imgur.com/a/dtUaXQF Happy to work with anyone to get this resolved.
