If I have a file with several characters in it, only a certain number of initial characters is displayed on the Lubuntu desktop and Xfce desktops.

For example, I have a file titled, "interesting-links-on-default-browsers". It shows as "interesting-links-on-def..." with both DEs. However, single-clicking on the file in Xfce shows the full title but the truncated title remains in Lubuntu.

It's not a big deal, but if it's just a matter of setting something somewhere to get the full title visible on single-click, I'd be grateful for pointers.

Edit: Lubuntu 12.10
Edit on 20121020: For clarification, I'm meaning the icons on the desktop and not the "icon view" mode in the file manager (PCManFM).
