-
- Yes, try using xscope (the X11 protocol decoder). It will greatly
- slow down executition of X clients. It should be part of 4.0.x IRIX
- and you can read the manual page to learn how to use it.
-
- xscope sits between an X client and server decoding the X11 protocol
- (in the process slowing down the conversation).
