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 ** Changed in: ubuntu Status: New => Incomplete ** Tags added: amdgpu ** Summary changed: - Freeze when switching users in Kubuntu 20.04 + [amdgpu] Freeze when switching users in Kubuntu 20.04 -- 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/1887710 Title: [amdgpu] Freeze when switching users in Kubuntu 20.04 Status in Ubuntu: Incomplete Bug description: Scenario: 2 users. The first user 1 created during the installation is working. Then I create a second user 2. I can switch the users at the beginning then at some point when I try to login with user 2 the screen freezes and one has to do a hard reset. Last time it happened after I set the desktop background picture to "Picture of the day - Bing" for user 2. Then I logged off and tried to log in again and I had a screen freeze. This happened several times.
