--help yields:

gnome-randr 0.1.1
A program to query information about and manipulate displays on Gnome with Wayland.

Default command is `query`.

USAGE:
    gnome-randr [SUBCOMMAND]

FLAGS:
    -h, --help       
            Prints help information

    -V, --version    
            Prints version information


SUBCOMMANDS:
    help      Prints this message or the help of the given subcommand(s)
    modify    Modify allows you to alter the current display configuration.
    query     Query returns information about the current state of the monitors. This is the default subcommand.

Where are the rest of the commands? The traditional xrandr commands don't seem to be working either.

I need to set 1.5x scale for one of my monitors - I used to do it with GNOME display settings but with update to GNOME 42, that seems no longer possible (the UI doesn't offer it despite 'scale-monitor-framebuffer' being set).

Your tool looked great, but sadly did not allow me to make the change:

gnome-randr modify --scale 1.5 HDMI-1
setting scale to 1.5
D-Bus error: Scale 1.5 not valid for resolution 3840x2160 (org.freedesktop.DBus.Error.InvalidArgs)
Scale 1.5 not valid for resolution 3840x2160

Can I do anything about this?

Hi :wave: nice tool you've made, thanks for your work!

Would be great to be able to configure display mirroring, as GNOME itself currently only allows either extended or mirror all.

Example: I have three displays attached and want to mirror 2 as my "primary", leaving the 3rd as an extended.

Main Change

Created an Action to handle changing monitor position in X and Y. Tied this action into the CLI. Tested functionality - tests pass.

Secondary Changes

This change also led me to refactor most of display_config. physical_monitor and virtual_monitor now share distinct types for:

• Transformation
  • Displacement
    • Handles X, Y, and Scale
    • Handles parsing CLI instructions
  • Orientation
    • Handles u32 encoding Rotation and Flipping
    • Handles parsing CLI instructions
• Connector/Vendor/Product/Serial (now MonitorDescription)

There are no longer two 'rotation' types ("Actions::Rotation" and "LogicalMonitor::Transform") - Actions::Rotation has been superseded, extending the CLI's rotation capabilities to include flipping, without breaking previous behavior.

I'm relatively new to Open Source / GitHub tradition, and I'm very very new to Rust. If there's something I can do to help in any way, or if I've made a mistake in some way, please let me know.

Hello, @maxwellainatchi. Thank you very much for this amazing tool! It works like a charm in my new Wayland env.

I'd like to know if is possible to implement brightness control and if you think that could be a good idea.

Motivation

My PC is quite old with a very obsolete AMD GPU:

$ lspci
...
01:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Opal XT [Radeon R7 M265/M365X/M465]

And I can't change brightness through system settings and neither by set /sys/class/backlight/acpi-video0/brightness.

Because of this I've been using Brightness Controller for a quite few years and it works very well in Xorg envs. I saw that they use xrandr to set brightness. So maybe your tool could help on this as well for Wayland envs.

I'm not saying that you should implement something to work in conjunction with Brightness Controller, it's just that your tool could control brightness as xrandr does.

Suggestion

# based on gnome-randr usage
USAGE:
    gnome-randr modify [FLAGS] [OPTIONS] <connector>

# suggestion
$ gnome-randr modify --brightness 0.75 HDMI-1

As you already know, in xrandr we have:

xrandr --output HDMI-1 --brightness 0.75

My setup

| Info | Value | |-|-| | Distro | Manjaro 21.2 | | Display server | Wayland | | Gnome | 41.3 | | gnome-randr | 0.1.1 |
