Slightly off-topic, Vladimir sounded as if there was any argument of supporting shared memory in X... AFAIK, the shared memory extension *is* part of Xorg! $ grep 'MIT-SHM' /var/log/Xorg.0.log (II) Initializing built-in extension MIT-SHM - the shared memory extension is also crucial for client-side font-rendering (xft/freetype) a.k.a. all those nicely anti-aliased texts in firefox and openoffice, besides DVD playbacks.
