Public bug reported:
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.
