How to set dark mode?

[PILIHU2022]

I use Arch LInux, and I want to set a global dark mode. Then the applications can all follow my system appearance. How can I do it?

Write in hyprland.conf the following.

exec = gsettings set org.gnome.desktop.interface gtk-theme "YOUR_DARK_GTK3_THEME"   # for GTK3 apps
exec = gsettings set org.gnome.desktop.interface color-scheme "prefer-dark"   # for GTK4 apps

env = QT_QPA_PLATFORMTHEME,qt6ct   # for Qt apps

Then reboot hyprland, open qt6ct and choose a dark theme for Qt apps.

for gtk4 apps this does not change anything

Yes, that's what I said.

That is probably because your portals are not working properly.

Install these packages:

• xdg-desktop-portal-gtk
• xdg-desktop-portal-hyprland

Then create the file ~/.config/xdg-desktop-portal/hyprland-portals.conf with the following contents:

[preferred]
default=hyprland;gtk

Fianlly, reboot the computer and try.

Ha nice, your method worked. Quick question, does that mean that it's a good idea to also have xdg-desktop-portal-kde on the machine ? Or is it a GTK thing.

With the hyprland and gtk portals you are good to go. You don't need more than those two at the moment.

The kde portal is made for plasma desktop specifically, it depends on plasma-desktop in fact. There is also a gnome portal made for gnome desktop. The gtk portal is a generic one that every environment can use with few dependencies.
