Qt5ct

Can anybody tell me where to find this I have looked and looked (Running mate)

The QT_QPA_PLATFORMTHEME environment variable is not set correctly (current value: gtk2, required value: qt5ct)

Put export QT_QPA_PLATFORMTHEME=qt5ct in either ~/.profile or /etc/environment and reboot.

stalebrim Ya that refreshed my memory on it made note of things this time...lol
