Public bug reported: I wanted to have a dark theme for Lubuntu.
I installed a custom GTK theme called Ultimate-Plata-Dark-3.36 which is quite dark. This only affected apps that used GTK. As per the instructions in the LXQt Appearance Configuration window, I selected the 'gtk2' Qt style after install qt5-style-plugins. Afterwards, apps such as qpdfview adopted the GTK theme. *EXCEPT* PCManFM, which stubbornly persists in its original light theme. How do I make PCManFM respect the system Qt Widget style?
