arc-theme VS Kvantum

You can write an issue/ask a question here. It's based on the original theme, which is not active since 2017, so I guess the packages in Linux distros are built from that fork.

The theme on this picture is Arc

arc-theme with kvantum look petty good imo.

Me just being lazy instead of looking for it myself...how does this work? For example, let's say I want to use the Arc Dark theme on F36/Gnome 42. The theme claims it includes a GTK4 variant (btw, Fedora uses this fork of the Arc theme according to the rpm spec, as the original has been unmaintained for some time). How do I tell Gnome 42 libadwaita apps to use the Dark Arc theme? If it's an export line in my .profile file, then I must have done something wrong, because that didn't work for me. What is this trickery you mention, please do tell!

If your theme is already configured for libadwaita, it should be possible to use it in place of the default Adwaita by overriding the GTK_THEME variable globally or for each application via *.desktop files. For example, to globally set Arc-Dark (from the Arc theme), add GTK_THEME=Arc-Dark to a config file in $HOME/.config/environment.d for Wayland sessions or $HOME/.xprofile for X11.

I'm using the arc-theme, however because almost every native GNOME app is being ported to libadwaita, it doesn't make really sense anymore to offer custom theme support.

I have been using arc-theme for close to 5 years and even when primary author moved on, it seems to be working well enough via jnsh fork (https://github.com/jnsh/arc-theme). Has gnome authors ever considered adopting an existing theme vs building something from scratch?

I just upgraded upgraded from 18.04 LTS to 20.04 LTS and my topbar theme is a mix of light and dark, I've been using the "arc-dark" theme. I'm not a linux expert..been using it as workstations at home for a few years... perhaps it is due the theme not being compatible anymore as I found a fork here "https://github.com/jnsh/arc-theme"

Ubuntu 20.04 GNOME Shell 3.36.9 Theme link: https://github.com/jnsh/arc-theme

Arc doesn't support GTK4 yet (Extensions app).

I'm using Kvantum engine with my custom Andromeda theme

I think Kvantum has support for theming both Qt6 and Qt5 apps now though so that might be worth trying if it bothers you that much.

The ones I know of are: Aurorae (built-in one), Kvantum (https://github.com/tsujan/Kvantum/tree/master/Kvantum) and Lightly (just a theme https://github.com/Luwx/Lightly). store.kde.org is down (at least I can't access it at the moment), so I've shared github links.

What about : https://github.com/tsujan/Kvantum ?

Make sure Kvantum is selected in the application style section of your look and feel settings. Read through the usage instructions on the Kvantum GitHub page.

Perhaps you can submit an issue

As for Kvantum, you'll need to either install it from your distro's repos if you're lucky, or if not you'll need to compile it yourself, you can check how to do that here.

It's written in QT, so you need a QT theme. There's the KvLibadwaita style for the Kvantum theme engine.
