Public bug reported:
I have a Lenovo ThinkPad P14s gen4 amd laptop, which has an integrated
GPU.
I installed Ubuntu 23.10, and it defaults to using Wayland and connected
it to an external Dell Dell P2720D monitor via HDMI.
The UI under Settings > Displays then "Mirror", the default setting
works, and I see the display duplicated as expected, with the large
external monitor having a low resolution limited to that of the laptop.
But if I switch to "Join" does not allow to Apply with message:
> Changes Cannot be Applied. This could be due to hardware limitations.
Logging off and changing to X allows "Join" to work, so it is a Wayland
issue.
Is there a way to make it work on Wayland? Mostly out of morbid
curiosity.
