[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. P.S. -- Please avoid top-posting.
