MIT-SHM is an extension to the X window system protocol which is handled by the default configuration of the sample server from MIT (and probably other vendors' servers, too). You can find out about this by typing `xdpyinfo' to your X display: ... number of extensions: 4 SHAPE >>> MIT-SHM Multi-Buffering MIT-SUNDRY-NONSTANDARD ... The MIT-SHM extension provides a fast transfer method for pixmap data for clients that run on the same machine as the server. I don't know about any programs that use it, but SHM should be beneficial for animation programs or so. -- Simon.
