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. ** Affects: xwayland (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xwayland in Ubuntu. https://bugs.launchpad.net/bugs/2048438 Title: Dual monitor extend (join) not working with Wayland with p14s ThinkPad laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xwayland/+bug/2048438/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
