No probs Ken,
It doesn't turn off the grid as such, but allows adjustment of the spacing between icons on the grid.
To fine tune it a bit more you could possibly try changing the value of the line XfdesktopIconView::cell-text-width-proportion = 2.0 to 1.5 or perhaps even 1.0.
It controls how much space is used to display the text under each icon.
It works on multiples of the icon size in pixels, so if you have a 20 pixel icon & it's set at 2.0, Xfce will reserve 40 pixels for the text.
It centres each icon in it's display area so it'll reserve 10 pixels either side of the icon + the 20 pixels of the icon itself.
If you change that number to 1.0 it keeps the text at the same width as the icon allowing them to be put closer together if desired.
Logout & back in again anytime you edit that file.
