Color profile mismatch on after resume from suspend

[GodTamIt]

This is a consolidation of discussion threads into an actual bug.

Threads

• Color profile mismatch on Nvidia GPUs after resume from suspend Hyprland#13036 (has logs)
• HDR breaks display after waking from sleep mode. Hyprland#13153 (has screenshots)

Symptoms

TLDR: everything is working perfectly fine on a dual-monitor setup on my 4090s - HDR is working perfectly fine. Then, I put computer to sleep and restore, all color on my monitors are washed out.

Some digging I did in the broken state:

1. When running drm_info, both connected ports show: "HDR_OUTPUT_METADATA": blob = 0
2. However, when running hyprctl monitors | rg "currentFormat", I get currentFormat: XBGR2101010 for both monitors.
3. hyprctl reload doesn't seem to do anything to push new color info to monitors.
4. Disabling and re-enabling monitors via hyprctl also did not seem to do anything.
5. In the hyprland logs, there are some interesting error messages:

ERR from aquamarine ]: drm: Cannot commit when a page-flip is awaiting

It seems that the compositor and driver states are out of sync. Hyprland is trying to allocate a XR30 buffer and is getting rejected.

Otherwise, my setup is on NixOS -- all other parts are working just fine.

Attempted Fixes

• drm: re-send HDR metadata blob on modeset #250
• drm: re-send ctm blob on modeset #256

I tested with the following overlay in NixOS and still see the above issues:

  aquamarine = prev.aquamarine.overrideAttrs (_old: {
    src = prev.fetchFromGitHub {
      owner = "hyprwm";
      repo = "aquamarine";
      rev = "d67142c8c0966c94ecf88beddb14003256d8058c";
      hash = "sha256-XXrDUeITQvDtejcRqJUnSCyjlU8pSDuOIBOA40udnPs="; # The real hash
    };
  });
