How can I change default X11 application?
Solution 1:
- cd to /usr/X11/bin
- rename the existing X symlink to Xquartz (to X_orig for example) in case you need to revert in the future to the "vanilla" config
- symlink X to your compiled binary.
Solution 2:
The XQuartz install docs have an alternate approach for installing their X11 binary. They use launchctl and set the DISPLAY to point to the socket for their server. I believe the program it runs (launchd_startx) listens on the socket and starts the X server when a connection is made. The nice thing about this approach is it leaves the original X11.app unmodified.
