I also have the same issue with two monitors connected, one of which in portrait mode. When selecting the second monitor to switch to portrait mode, it extends the rotated monitor about halfway into the second screen and they are shown as overlapping in the display settings. It is not possible to rotate the monitor.
A temporary workaround is to set the rotation with xrandr or with the NVIDIA X Server. However, once the machine is rebooted or the screen lock turned on, the settings are "forgotten" as if one made no changes to the screen orientation at all, back to zero. Here is also a thread on reddit with more people experiencing the exact same issue: https://www.reddit.com/r/Ubuntu/comments/g82u58/cant_rotate_monitor_orientation_in_ubuntu_2004/ About my system: OS: Ubuntu 20.04 LTS x86_64 (all up to date) Kernel: 5.4.0-26-generic Uptime: 16 mins Packages: 1575 (dpkg), 9 (snap) Shell: bash 5.0.16 Resolution: 2160x3840, 3840x2160 DE: GNOME WM: Mutter WM Theme: Adwaita Theme: Yaru-dark [GTK2/3] Icons: Yaru [GTK2/3] Terminal: gnome-terminal CPU: Intel i7-6900K (16) @ 3.200GHz GPU: NVIDIA GeForce GTX 1080 Ti Memory: 2385MiB / 128743MiB If needed, I can provide more information. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1874217 Title: Dual monitor setup with secondary monitor in portrait-right mode cause tiled windows to occupy 1.5 monitors Status in gnome-shell package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Bug description: I will provide below a screen capture. I think this bug is related to this one : https://bugs.launchpad.net/dash-to-dock/+bug/1869571 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.
