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 Desktop Packages, which is subscribed to gnome-control-center 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 Status in gnome-control-center: Unknown Status in Mutter: Unknown Status in gnome-control-center package in Ubuntu: Triaged Status in mutter package in Ubuntu: Confirmed Bug description: I'm on Ubuntu 20.04 AMD64 fully up to date and freshly rebooted. I use dual screen : the main screen is on the left side (32"), the secondary screen (19") is at right and in portrait mode (rotated right). The window are improperly growed : they extend from full main screen to half the "witdh" of the secondary screen. Additionnally, the « pop-up » menus (eg. from settings) do not appear at the right place (see screen capture in comment). The problem disappears if I revert the orientation of secondary screen from « portrait turned right » to « landscape ». I do have gnome-shell-extension-ubuntu-dock in version 67ubuntu20.04.5, but still got the problem.
