Either the bug title should be renamed to something more generic or a new bug should be created. As far as I can tell, many users have this problem but don't necessarily have the screen overlap issue. At least, overlap is not mentioned in [the reddit post](https://www.reddit.com/r/Ubuntu/comments/g82u58/cant_rotate_monitor_orientation_in_ubuntu_2004/) that links here.
In any case, how can I help find the bug? NVidia server settings can fix the monitor rotation, but I cannot figure out how to persist those changes. My situation is even worse than described. Sometimes when applying the settings in "Displays," the setting changes to "Single Display" from "Join Displays" without my input, and the monitor I want in portrait mode goes black while Gnome still thinks it is part of my desktop... even after I click the "revert" button. As a software engineer I would like to help to track down the bug and fix it. However, I don't see any instructions in mutter's README.md about how to build and test from source. Same for https://github.com/GNOME/gnome-control-center. Any pointers to documentation would be appreciated. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1874217 Title: [nvidia] Dual monitor setup with secondary monitor in portrait-right mode cause tiled windows to occupy 1.5 monitors To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-control-center/+bug/1874217/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
