X uses various authentication schemes to ensure that bad people don't connect and screw you up. I believe that at the level X works at, it can't tell whether or not it's the local root trying to connect, so root doesn't get any special privileges here. solution: there are many. - use xhost: not recommended, but if you want to, read the xhost man page - use xauth: as root "xauth merge $(USER'S HOME)/.Xauthority" (or something like that). This gives root the correct "magic cookie", which it uses to authenticate itself to the X server - "export XAUTHORITY=$(USER'S HOME)/.Xauthority" basically does the same thing as xauth (in terms of end result), but differs in details that you may or may not be interested in. man xauth if you want to learn more. - use sudo: sudo is sorta like su, except that it allows more control -- it allows you grant certain users the authority to run certain commands as root (or some other user), instead of having to give the root password to everyone who needs to do something as root. It also automagically sets up the XAUTHORITY variable - ssh into your root account, and use ssh's root forwarding: probably a waste of CPU This has got to be a documented FAQ somewhere.

I use the idectl script from the hdparm package (it's in the /usr/share/doc/hdparm/examples directory), to force the OS to rescan the IDE bus. That makes it load the modules properly. I don't remember if it makes any modules unload, though. -- Hubert Chan <hubert@uhoreg.ca> - http://www.uhoreg.ca/ PGP/GnuPG key: 1024D/124B61FA Fingerprint: 96C5 012F 5F74 A5F7 1FF7 5291 AF29 C719 124B 61FA Key available at wwwkeys.pgp.net.
