Opening Settings -> Display and selecting an orientation other than Landscape doesn't work.
Similarly, selecting Fractional Scaling and then picking a scale factor has no effect.
This is a recently installed Ubuntu 20.04, fully updated, on a recently released laptop/tablet that uses an AMD Ryzen 4500U integrated CPU/GPU. It is possible that the GPU is not being detected by Ubuntu and that is the root cause of the problem. I couldn't find an easy explanation online about how to tell whether a GPU was detected or is in use. I did try running "tlp-stat -g" to get graphics status, but it returns without printing anything except its version number (1.3.1).
When I choose an orientation, such as Portrait Right, the setting changes and an "Apply" button appears in the top of the Settings window. When I press it, up pops up a dialog asking whether I want to "Keep these display settings?" with two options, keep or revert. The rest of the screen goes grey behind the dialog box, but I can already see that the "Orientation" setting back in the Settings->Display window has been reverted to "Landscape" without me doing anything. Whether I choose keep or revert, or merely let it time out after 20 seconds, the result remains the same -- the display stays in Landscape mode and the setting that I had made is reverted.
Regarding scaling, I can set the display scale to 100% (default) or 200%, successfully. When I turn on the "Fractional Scaling" slider, the graphics around the edge of the screen increase in size (the icons in the left-hand dock, the text in the top bar), but the Scale settings do not change (they remain "100%" and "200%"). However, if I switch to a different setting (for example, "Mouse & Touchpad") and then back to "Displays", the Scale settings have changed. I have included three screenshots (original screen, Fractional Scaling on, and after switching to and from Displays.
When I attempt to set a fractional scale such as 125%, the "Apply" button appears in the upper right corner. When I press that, the display does not scale, a pop-up asks if I want to keep or revert the setting, but looking back at the Displays settings, the Scale has already reverted to 100% (as above with the Orientation).
The display has been rock-solid before this, but now it started showing artifacts, such as
previous copies of the Displays window. I've enclosed a screen shot. Merely taking a screen shot also wiped out parts of the display to white; I took another shot to show that.
