Error running on LxQt

[Daniel Santos]

I have ArchLinux and I am strying to run plank on LxQt environment.
I have installed plank using `pacman -S plank`.
Plank version is: 0.11.89-2

When I run:
$ plank

I get this error message:
CRITICAL 16:42:10.085284]bstractMain:255] Only X11 environments are supported.

`gd --args plank -d` gives:
