The updated mutter package (50.1-0ubuntu2.4) is tested on the mentioned device (https://certification.canonical.com/hardware/202603-38512/) and verified that the patch is working and mutter won't supply unsupported rates outside of +-0.5Hz tolerance to GNOME Settings. Connector info for the device: ``` Connector info -------------- [CONNECTOR:511:eDP-1]: status: connected physical dimensions: 300x190mm subpixel order: Unknown CEA rev: 0 DPCD rev: 14 audio support: no DP branch device present: no HDCP version: No Connector Support max bpc: 10 fixed modes: "2560x1600": 120 561410 2560 2608 2640 2720 1600 1630 1636 1720 0x48 0x9 "2560x1600": 48 224570 2560 2608 2640 2720 1600 1630 1636 1720 0x40 0x9 "2560x1600": 120 561408 2560 2608 2640 2720 1600 1630 1636 1720 0x48 0xa modes: "2560x1600": 120 561410 2560 2608 2640 2720 1600 1630 1636 1720 0x48 0x9 "2560x1600": 120 561408 2560 2608 2640 2720 1600 1630 1636 1720 0x48 0xa "2560x1600": 48 224570 2560 2608 2640 2720 1600 1630 1636 1720 0x40 0x9 [CONNECTOR:520:HDMI-A-1]: status: disconnected [CONNECTOR:529:DP-1]: status: disconnected [CONNECTOR:539:DP-2]: status: disconnected [CONNECTOR:548:DP-3]: status: disconnected ```
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 50.1-0ubuntu2.4 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 +-0.5Hz tolerance is listed in the output Compare to the previous rejected upload, the tolerance update includes some more modes that the stricter tolerance filtered out previously: ``` --- ./mutter_50.1-0ubuntu2.3.rates 2026-08-25 08:49:15.727750475 +0000 +++ ./mutter_50.1-0ubuntu2.4.rates 2026-09-09 02:53:52.874377590 +0000 @@ -1,16 +1,39 @@ "[email protected]" "[email protected]" "[email protected]" +"[email protected]" "[email protected]" "[email protected]" "[email protected]" "[email protected]" +"[email protected]" "[email protected]" "[email protected]" "[email protected]" +"[email protected]" +"[email protected]" +"[email protected]" +"[email protected]" +"[email protected]" "[email protected]" +"[email protected]" "[email protected]" +"[email protected]" "[email protected]" +"[email protected]" "[email protected]" +"[email protected]" "[email protected]" +"[email protected]" +"[email protected]" +"[email protected]" "[email protected]" +"[email protected]" +"[email protected]" +"[email protected]" +"[email protected]" +"[email protected]" +"[email protected]" +"[email protected]" +"[email protected]" +"[email protected]" ``` ** Tags removed: verification-needed-resolute ** Tags added: verification-done-resolute -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in 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 -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
