AUR package request about nody-greeter

[stevenxxiu]

Btw I see this depends on libx11-dev on the home page, hence X11. Does it support Wayland instead? That's a key feature of LightDM.

Any chance of making an AUR package.

Yeah, it's possible, but I haven't had time to do it; perhaps in a future~

No, Wayland is not supported in LightDM, hence it's not supported in web-greeter/nody-greeter/sea-greeter.

No, Wayland is not supported in LightDM, hence it's not supported in web-greeter/nody-greeter/sea-greeter.

It does say on https://github.com/canonical/lightdm/blob/ba7f6efc5c802aa87520b526ab5bc72b81669311/README.md:

Supports different display technologies (X, Mir, Wayland ...).

[JezerM]

I guess it means that LightDM can execute those display technologies as sessions. LightDM always executes an X server.

[stevenxxiu]

Thanks for the reply. I'm just thinking of getting rid of X11 entirely in the future so want to get this right.

Looking at lightdm dependencies, it includes xorg-server anyway so I suppose this doesn't matter much, at least the way things are packaged now.

I googled more and https://lists.freedesktop.org/archives/lightdm/2019-June/001172.html does have the LightDM author saying:

LightDM doesn't depend on X and you can have a Wayland based greeter.

If you install the greeter .desktop file into /usr/share/lightdm/greeters and set X-LightDM-Session-Type=wayland LightDM will launch this greeter without an X server.

That seems to me that the greeter doesn't have to use X11?

Oh, I didn't know that. So it seems it doesn't have to always use X11, however there are some minor breakpoints about this, like the layout manager. LightDM uses libxklavier to manage the current system keyboard layout, which only works on X11; maybe it works on Wayland through X-Wayland, but I'm not sure.

Though, I tried to run web-greeter and nody-greeter in a Wayland environment a long time ago and they did work, so although it's not supported at all, it could be executed in Wayland.

Recently an upgrade to webkit2gtk broke lightdm-webkit-theme-aether yet again, so I'm looking at this project once more.

I see that someone made a package https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=nody-greeter. I tried but this does not build, as I'm guessing this project relies on a Node.js version that is too old. The latest on Arch Linux is v20.6.1, while the readme of this project says it supports up to v16.

So if you could update the packages for the latest Node.js, that'll be fantastic!

@stevenxxiu I installed nody-greeter on my Arch by using paru and it has been installed with no issues. Do you know a list of interesting LightDM themes compliant with nody-greeter?
