What Doug didn't mention is that he's seeing this on a 1U rackmount server, that has an onboard ATI RageXP chipset. Not sure how much that matters, however i was always of the belief that you shouldn't be running X on a rackmount server unless something that the server was serving required X. -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Lonni J Friedman [EMAIL PROTECTED] Linux Step-by-step & TyGeMo http://netllama.ipfox.com _______________________________________________ Linux-users mailing list [EMAIL PROTECTED] Unsubscribe/Suspend/Etc -> http://www.linux-sxs.org/mailman/listinfo/linux-users
