Thank you for taking the time to report this bug and helping to make Ubuntu better.
Bug reporting is mostly about finding & fixing problems thus preventing future users from hitting the same bug. I suspect a Support site would be more appropriate, eg. https://answers.launchpad.net/ubuntu. You can also find help with your problem in the support forum of your local Ubuntu community http://loco.ubuntu.com/ or asking at https://askubuntu.com or https://ubuntuforums.org, or for more support options please look at https://discourse.ubuntu.com/t/community-support/709 FYI: You've tagged your bug report is with the `ubuntu-release-upgrader` tool that upgrades a system to a later release (ie. 20.04 to 21.10/22.04), yet appear to not have used that function (ie. `do- release-upgrade`). It may your issue relates to the linux kernel instead, ie. wrongly filed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1971638 Title: Second Monitor detected but always turn black screen.
