[qubes-users] Qubes Manager not honoring colour scheme selection

I tried this but didn't succeed.

sudo qubes-dom0-update qt5-qtstyleplugins
sudo qubes-dom0-update
export QT_QPA_PLATFORMTHEME=gtk2

cat /etc/environment QT_QPA_PLATFORMTHEME=gtk2
cat: 'QT_QPA_PLATFORMTHEME=gtk2': No such file or directory

Qube Manager is still white ^^. Any ideas?

You have to actually edit the file `/etc/environment` in order to insert the string `QT_QPA_PLATFORMTHEME=gtk2` into that file, then reboot afterward.
