Hi, probably a noob question, but I see

MAX_PREFERRED_REFRESH For the specified displays, use the maximum avalable refresh rate for resolution of the preferred mode. e.g. when preferred mode is 1920x1080@60Hz, use 1920x1080@165Hz

in documentation. How do I set preferred mode? (on sway specifically)

I have these modes

D [14:58:34.510]     mode:     1920x1080@60Hz

with 3840x2160@30Hz (preferred). However I would like to use 2560x1440@60Hz (I don't really care if it is preferred or no). Setting output HDMI-A-1 res 2560x1440@60Hz (or with mode) doesn't seem to work, since way-displays will override it. Can you please help setting my resolution? Thanks

First of all I love this program, I like that way-displays turns on all monitors when you first run it without configuration, and the config is very straightforward. And it autoupdates when the config is saved, much faster than wlr-randr and wdisplays.

But currently all monitors are turned on by default. It would be great to specify which monitors are powered on or off. One way to implement this in the config is to only turn on monitors listed in the ORDER. For example:

eDP-1 on only:

ORDER:
    - 'eDP-1'

HDMI-1 on only:

ORDER:
    - 'HDMI-1'

Both on: (and keep the current behavior of turning all monitors on if the order key is undefined or empty)

ORDER:
    - 'eDP-1'
    - 'HDMI-1'

Maybe ORDER could also be renamed to DISPLAYS to be more intuitive.

What do you think?

Hey there!

Quick question, is there an option for the tool to try to force the maximum refresh rate using the resolution from the "preferred" configuration (for stability)?

Thanks for the great package!

By default dissimilar-sized displays align by the top edge which is not easy to accomplish in the physical world with a laptop on a desk with an external display. Thus, the mouse, for example, does not 'flow' properly from one display to the next.

It would be helpful if there were the ability to set the position alignment to 'Bottom', and have way-displays do the math to make it happen. I would propose that Bottom should be the default, also.

When I close my laptop lid, the workspaces on the laptop monitor are not moved to the external monitor at all. The message Lid closed does not show up in the logs either.

However, cat /proc/acpi/button/lid/LID0/state still outputs the correct state of my lid.

Hello, do you have some document to how implement "The client could use the same IPC socket and YAML streaming protocol as the CLI." our application ( a simple desktop ) runs on sway and we want dev a go app to control monitor . Regards, Nicolas

https://github.com/artizirk/wdisplays offers a GUI to set wayland output properties:

• scale
• position
• size
• refresh
• translation

way-displays lacks a GUI however persistently supports all the above, with yaml file and CLI interface.

wdisplays and way-displays could work together via IPC API or be merged.

Following an update, invoke a user executable.

API or (scraped) CLI could be used during the executable.

Alternatively, the config / changes could be rendered as YAML in a file.

Hi! as of today way-displays can be installed via nix package manager (Linux distros using nix and NixOS). The package is available from the unstable branch of nixpks. Probably will be merged in the next release as stable.

I am the current maintainer for that package, I will update it when new versions will be available. But if any of you wants to do it the necessary changes to update the package are realy simple.

For the future we can think to ad a CI/CD process so that the package can be directly downloaded from GitHub instead of building it on the host platform.
