When I maximize a window in Ubuntu 11.04, the close, minimize and maximize buttons change to these nice ones
Where are they located on the filesystem? I would like to build a theme out of them but want the originals.
The buttons in question for Ambiance are in /usr/share/themes/Ambiance/metacity-1. Each theme has it's own set using the same file names. You can edit these png files. I changed mine from orange to a shade of blue I liked. The system uses a base name like "close" and appends let's say "_focused_prelight.png" to get the file name for the state to display.
