As Andrew Atrens wrote: > Does the X-server run any faster with MIT-SHM than without? No, it doesn't. The only thing is that it disables the MIT-SHM extension if no SYSVSHM is available in the kernel (it catches SIGSYS, and attempts to issue a shmget() call). MIT-SHM is an extension that must be explicitly used by the clients, and AFAIK only few clients actually use it. It is not to be confused with a local transport via shared memory (which doesn't exist in any XFree86 server, and to the best of my knowledge, neither in the Xig server). -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
