I know Red Hat has a lot of standard daemons (PCMCIA, ISDN, etc) that are started by default - have you used chkconfig or redhat-config-services to shut off unneded services? The kernel also uses a lot of free memory for I/O caching - even my P4 w/ 1GB RAMBUS shows 90% memory consumption in /proc/meminfo. Caching is a low-priority memory allocation - when the system needs memory for active processes, it should give the memory to the process. BTW, unless you are using a framebuffer kernel-level driver, X is handled almost exclusively in userland. On SPARC32 (for example) framebuffers are pretty much the only way to get X working, but mostly, XFree86 and the X.org server that comes with FC2 use mostly user-space drivers. - To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
