Try this

Dark Theme for [Qubes Manager] Not Working in 4.1

In dom0: $ sudo qubes-dom0-update qt5ct qt5-qtstyleplugins Then, run: $ export QT_QPA_PLATFORMTHEME=qt5ct Then: $ qt5ct Here you select Style: gtk2 (to match your current XFCE settings) and you can select also Fonts and Icon Theme. Only QT_QPA_PLATFORMTHEME=qt5ct needs to be made persistent.

Another solution what I did is to edit /etc/environment in dom0

QT_STYLE_OVERRIDE=adwaita-dark

and logout or reboot.

This application is not configured correctly.

The QT_QPA_PLATFORMTHEME enviroment variable is not set (required value: qt5ct)

[applesauce]

Could this be because i didnt make “QT_QPA_PLATFORMTHEME=qt5ct” persistent?

If so, how can i make it persistent?

The same thread explains what you need to do

Dark Theme for [Qubes Manager] Not Working in 4.1

export QT_QPA_PLATFORMTHEME=gtk2 in /etc/environment equally does the trick, if the respective dependencies are installed. Not so important in dom0 but if you want to push it into all your templates, it’s nicer to do it this way instead of having to run qt5ct.

I could only get the export to work when I execute the manager from the terminal.

If you edit /usr/share/application/qubes-qube-manager.desktop

and change the Exec line to:

Exec=/bin/sh -c 'export QT_QPA_PLATFORMTHEME=gtk2; qubes-qube-manager'

then it should also be dark mode when you execute the manger from the application menu
