I am running on Arch Linux using Openbox as the window manager. I want to assign icons to some programs that are using the generic icon.
This is helpful because when I do an Alt-Tab, I will know the program based on the icon it shows. Currently, I have some programs, like Xterm and Xpdf, using the default icon and doing an Alt-Tab when both are open can be confusing.
I have Firefox, Geany and Leafpad installed and I noticed that they have icons during an Alt-Tab.
So how do I set this up for the other programs that don't?
