Thank you for fixing this bug. Installing mutter 3.36.4-0ubuntu0.20.04.1 and libmutter 3.36.4-0ubuntu0.20.04.1 from focal-proposed has resolved this issue for me.
Note: The updated libmutter from focal-proposed also had to be explicitly installed by me, as it was not automatically pulled in when updating mutter. Steps: 1) Enabled focal-proposed 2) apt update 3) apt install mutter libmutter 4) Disabled focal-proposed 5) Removed ~/.config/monitors.xml and ~gdm/config/monitors.xml 6) Rebooted 7) After login, I successfully applied my desired monitor configuration (changing the primary monitor and setting other monitor to portrait orientation). Side notes: 1) I still had to copy ~/.config/monitors.xml to ~gdm/.config/monitors.xml for the correct primary monitor and orientation to be set on the login screen. 2) After applying the display configuration, the icons in the top-right of the gnome panel appeared blured (network/bluetooth). This was resolved by applying 150% fractional scaling and then applying 100% scaling again in the gnome display settings. I haven't had time to reproduce this to know if it's a one-off or ongoing bug. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1874567 Title: [nvidia] Rotating secondary monitor to portrait fails, results in landscape To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1874567/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
