I enabled jammy-proposed and upgrade xserver-xorg-video-amdgpu. Made sure Xorg was selected in GDM, then connected an external monitor which routes to AMDGPU instead of Intel. Close the lid to make the external monitor the single display, the refresh rate is smooth so the issue is resolved.
I also boot up an AMD APU laptop to test the package and no regression was found. ** Tags removed: verification-needed verification-needed-jammy ** Tags added: verification-done verification-done-jammy -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-amdgpu in Ubuntu. https://bugs.launchpad.net/bugs/1987038 Title: Fix slow refresh rate when AMD GPU screen in reverse prime mode To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1987038/+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
