No lower VRR range for display shown in Settings

[Eduard Kachur]

Description: Ubuntu Noble Numbat (development branch)
Release: 24.04

Package: mutter
Version: 46.0-1ubuntu9

mutter is built without libdisplay-info and this is required for having lower VRR range for display.

[Daniel van Vugt (vanvugt)]

If true then it sounds like the entire VRR feature should be automatically disabled when it's missing(?)

[Daniel van Vugt (vanvugt)]

Are you:

(a) experiencing a black screen like https://gitlab.gnome.org/GNOME/mutter/-/issues/3419 ?
(b) commenting on a lack of options in Settings?
(c) commenting only on the build config (-Dlibdisplay_info=disabled)?
(d) experiencing some other problem?

Hello, (c) (d).
More info here https://gitlab.gnome.org/GNOME/mutter/-/issues/3434
Sorry, should've linked it right away.

LFC on supported monitor seems to be working well. Looks like a visual issue.

[Daniel van Vugt (vanvugt)]

We could MIR libdisplay-info [edit: bug 2071396], it seems to have practically no dependencies. But on the other hand, the amount of code in Mutter that actually depends on "HAVE_LIBDISPLAY_INFO" is quite small. It could be replicated inline within Mutter, though I doubt upstream would want to.

Tracing the field relevant to this bug through the Mutter code (meta_monitor_get_min_refresh_rate), it doesn't look like it has any real function other than a cosmetic one in returning the minimum refresh rate over D-Bus back to the Settings app. Perhaps it should be used in future if that helps to prevent bug 2066080, but for now this bug seems to be purely cosmetic and unimportant.
