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/
