[solved] GNOME's Mutter HDR mode can't be enabled.

According to this article: https://www.phoronix.com/news/Mutter-Ex … -HDR-Modes

I should be able to enable this experimental feature in Gnome 44, but I still can't enable HDR.

There was an instruction for me to do it: https://gitlab.gnome.org/GNOME/mutter/- … te_1705022
When I input "global.compositor.backend.get_monitor_manager().experimental_hdr = 'on'" in the "looking glass", nothing has happened.

Yep, I have tried it with MPV player in TTY, and it is enabled.
So can gamescope-session.
