Many thanks for help and the pointers.

Removed all three.

After the above env variables have been removed glxgears no longer starts:

% glxgears
Error: couldn't open display (null)

Same with kwrite

  % kwrite
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even 
though it was found.
This application failed to start because no Qt platform plugin could be 
initialized. Reinstalling the application may fix this problem.

Available platform plugins are: bsdfb, minimal, offscreen, vnc, xcb.

Abort (core dumped)

Same with xclock

  % xclock
Error: Can't open display:

For the same reason couldn't check glxinfo:

% glxinfo
Error: unable to open display

Firefox also still dumps core, I will try with tmpfs next.

However, good news is that gtk3-domo opens fine, and even keyboard works.

sway -d prints the following:
