Thanks for the report. It seems like zbus 2.1 is incompatible with zbus 2.0 even though the version change was "minor". And, apparently, cargo install ignores Cargo.lock.

[MaxVerevkin]

This should be fixed now.

@MaxVerevkin Thanks for the quick update, now it compiled and installed, but another issue appeared where I can't run it: wl-gammarelay-rs run New output: 5 Cannot initialize output 5: no gamma control manager

Nor skipping that part and just try to set brightness busctl --user set-property rs.wl-gammarelay / rs.wl.gammarelay Brightness d 2: Failed to set property Brightness on interface rs.wl.gammarelay: The name is not activatable

I'm on Fedora 35, GNOME 41.3 with NVIDIA drivers, maybe that has something to do with it.

This tool uses wlr-gamma-control-unstable-v1 protocol, which Gnome (apparently) doesn't implement. I don't think I can do anything in this situation 😔.

[egrist]

Ah I understand, didn't know GNOME didn't have it implemented, looking forward to testing it when it does. Thanks again.

Unfortunately, beased on https://gitlab.gnome.org/GNOME/mutter/-/issues/1635 they will never implement a way for third party apps to control the gaama table.
