As has been strongly encouraged, I spend most of my time on my linux box as a mortal user. Every once in a while I need to go 'root-in' around some system files to set up a new application that I've downloaded (or for whatever reason?). Sure I can type $ su root at the promt and become root but I cannot use the x-server - any attempts result in a message
Xlib: connection to :0.0 refused by server Xlib: Invalid MIT-MAGIC-COOKIE-1 key ... Also use xhost program... Imagine my horror to find I have an invalid magic cookie! Do I really have to use xhost in order to use an xwindows session started by another user? -Chip Grandits
