Like I said some folks here clearly need to get over themselves. Don't remember any vote in which any of these dudes were elected the grand imperial poobah or high mucky muck over anyone else on this forum.
Also just for the record Bulkley and NFT5, what Wizard10k if referring too is the fact that every display manager other than GDM = (gnome display manager of course)starts the X process as root. Pop open a terminal on your system and watch in "top". It'll show who owns the process, if its root, it'll say it.
Note: I know lightdm does, I don't even have a DM anyway, really don't care if the X process is running as root regardless. Though w/o a DM, the Xorg process is running under my user. It's been awhile so not 100% all DM's other than GDM do so either. Oh well, life goes on fellow nixers.
