Probably. The problem is "which one". I do not know (I have never used LXDE)  
but it probably is below ~/.config. You can even move/rename that entire  
directory and see if that solves you problem. If so, you can then restore  
some of the folder ~/.config used to contain (if you do not want to  
reconfigure by hand many applications).
