Test step used: 1. Use `busctl --user call org.gnome.Mutter.DisplayConfig /org/gnome/Mutter/DisplayConfig org.gnome.Mutter.DisplayConfig GetCurrentState --json=short | jq .data[1][0][1].[][0]` to get the current modes supplied by mutter (50.1-0ubuntu2.2) before update and check that there's unsupported refresh rate. 2. Enable resolute-proposed in ubuntu.sources and run `apt update` 3. Update mutter to 50.1-0ubuntu2.3 with `apt install -t resolute-proposed mutter` 4. Restart gnome-shell, for example a reboot is used in this case 5. Use the same command in 1 to verify that only rates listed in connector info within +- 0.1Hz tolerance is listed in the output -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2163136 Title: [SRU] QHD panel doesn't support 60Hz refresh rate but Ubuntu OS can see 60Hz on display setting To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/2163136/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
