This code lives in the X11 libraries: https://tronche.com/gui/x/xlib/display/opening.html > Also where in the source code is the socket located at > ~/.xpra/ip-XXX-XX-XX-5455 read from / written to? I'm not sure what you're asking, the code that interacts with the sockets is in various places, ie: http://xpra.org/trac/browser/xpra/trunk/src/xpra/platform/dotxpra.py http://xpra.org/trac/browser/xpra/trunk/src/xpra/scripts/main.py http://xpra.org/trac/browser/xpra/trunk/src/xpra/scripts/server.py The actual socket path definitions are per-platform, here's the stub: http://xpra.org/trac/browser/xpra/trunk/src/xpra/platform/paths.py If you tell us what you're trying to do, we can give you more specific pointers.
