Comment 0 for bug 1916497

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?
