I don't use xdmcp, and I only use GNOME, so I'm not exactly sure what is the best thing to do in this setup. Maybe someone else can answer that. It seems to me that you should probably be running dbus and hald on both machines. You might also try removing the --exit-with-session from dbus-launch to see if that helps. >=20 >=20 > In addition I get this kernel message every second on the mouse and keybo= ard > box (Compaq Armada 1700 FBSD 7.1-stable i386) after I launch dbus > and hal daemons: >=20 > acd0: FAILURE - unknown CMD (0x03) ILLEGAL REQUEST asc=3D0x24 ascq=3D0x00= sks=3D0x40 0 > x00 0x00 >=20 > What does this mean? Should I be worried? No, these messages do not indicate a problem.
