I installed Ubuntu 12.10 via mini-iso, after that I installed xinit, xorg, fluxbox, xterm, pcmanfm , chromium-browser and lxappearance. There is for now one set of icons, in lxappearance I chose the icon set and applied but they don't show up in pcmanfm, there I see only text.
How do I get pcmanfm to show folder icons?
Found the solution:
Forget lxappearance.
Make a text file called .gtkrc-2.0 and put the following line in it:
gtk-icon-theme-name = "full icon theme name"
(of the theme you want, which has to be located in /usr/share/icons)
Save it in /home/username, and there will be icons!
For more gfk configuration use the following lines in .gtkrc-2.0:
#sets the font
gtk-font-name = "sans 8"
#sets the theme
gtk-theme-name = "Industrial"
(provided the gtk engine is installed)
