Basic customization of LXDE.
I haven't wasted time looking for some alternative background, but since I would like to modify the conky configuration file to adapt it to the colors of the GTK theme, I think I'll have to look for someone.
I made some minor changes to the application menu icon on the LXDE panel. It doesn't convince me at all, but the text of the default icon is unreadable with the use of dark themes
