Public bug reported:
Hi, I'd like to report the following bug. I'm trying to setup multiple
displays, but whatever settings I try to set, after pressing 'Apply' and
'Keep Settings', they revert back to the previous settings.
I have one built-in laptop display (D1) and one external display (D2),
connected via a USB-C dock using DisplayLink and HDMI. Display Mode is
set to 'Join Displays'.
It seems whatever settings I change, they don't persist. I tried the following
settings:
- Change the primary display from (D1) to (D2). Reverts back to (D1) being the
primary.
- Change the order of the displays to match my physical setup (D2 on the left,
D1 on the right). Reverts back to D1 on the left, D2 on the right.
- Change the order of the displays putting D1 on top of D2. Reverts back to D1
on the left, D2 on the right.
- Change the refresh rate of D2 from 60 Hz to 50 Hz. Reverts back to 60 Hz.
If you need any further information, please let me know.
