I am struggling to set Qt variables using hyprqt6engine. As a test, I’ve set a large font size and am then opening a Qt application to see if I can get it to take effect. I use uwsm to launch hyprland, and so I have the following configurations:
# ~/.config/uwsm/env
export QT_QPA_PLATFORMTHEME=hyprqt6engine
# ~/.config/hypr/hyprqt6engine.conf
theme {
font_size = 200
}
Unfortunately, this doesn’t seem to work. I’ve tried using hyprland without uwsm, setting the environment variable in hyprland.conf:
# ~/.config/hypr/hyprland.conf
env = QT_QPA_PLATFORMTHEME,hyprqt6engine
but this hasn’t worked either. Any suggestions as to how to troubleshoot this? Things I have tried: rebooting or restarting hyprland, using hyprland with or without uwsm, multiple different Qt applications, making sure the environment variable is set, checking the systemd log, checking the hyprland log.
I’m running Arch and installing hyprqt6engine using the AUR:
# pacman -Qs hyprqt6engine
local/hyprqt6engine 0.1.0-2
QT6 Theme Provider for Hyprland
local/hyprqt6engine-debug 0.1.0-2
Detached debugging symbols for hyprqt6engine
Thanks for any thoughts!
