[Bug 1971638] Re: Second Monitor detected but always turn black screen. If I turn off and on again, the screen will turn back to normal but turn back to black screen after few seconds

[Chris Guiver]

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.
