I'm trying to change the desktop font color in xubuntu after I replaced thunar with nautilus to be the default file manager. Right now I have gray text color which is not visible on almost any wallpaper. I set up the gtk theme using gnome-tweak-tool but it's not using it because in the css files and gtkrc file for gtk2 the text color is set to #ffffff
The problem is that nautilus and xfce are not a good match because nautilus tries to take over the desktop - which results in a kind of gnome/nautilus desktop, other than the normal Xfce desktop. I could not find a way to keep and use Nautilus in Xfce so I had to give it up because I didn't need it - and now I don't have this problem anymore. If you want to keep Nautilus you have to deal with this problem. See one suggestion here and also you may find about a similar problem here. Nautilus lovers tend to blame xfce for this problem, I see it as an incompatibility and think that this is more a Nautilus issue - as a file explorer designed to be the default program in other environments than Xfce.
I got this working. Xubuntu 12.04, transition from Thunar to Nautilus, including default desktop management.
Once you've transitioned to Nautilus to manage your desktop, the text of desktop icons will be grey or some other unreadable colour. To change this:
That should do it!
Side note: change the new nautilus desktop background with dconf editor, at the following location in the tree: org -> gnome -> desktop -> background
