In this case Google is a friend: "linux PS1"  I am so pleased with my 
PS1 value that I have kept it through dozens of distributions.

PS1='\[\033[1;33m\]# \w\n\r# \[\033[0m\]'

Can't stand a huge prompt, displayed over and over.  I usually put it in 
~/.bashrc (you will have to comment out some stuff) It's in yellow so 
only looks good if the background is black.  I also like a slightly 
larger than default font.
