Problem to access X desktop from a root terminal
It never happened to me under Red Hat 9, but when I am working in KDE as a normal user and try to execute emacs from a terminal, in which I am su, I occasionally get the following error message:jeltsch@mcblpc2:~ suPassword:mcblpc2:/home/jeltsch emacs test.txtXlib: connection to ":0.0" refused by serverXlib: Invalid XDM-AUTHORIZATION-1 key (failed key comparison)emacs: Cannot connect to X server :0.0.Check the DISPLAY environment variable or use -d'.Also use the xhost' program to verify that it is set to permit connections from your machine.
