I realize that this is a bit late, but I cant resist sharing my 'su'
alias to handle this in a somewhat general fashion, including the case
of NFS-mounted and 'nobody'-unreadable home directory that Casper
mentioned ('super' is the name of my NFS server):
# make sure authority file is readable when we su
if ($?DISPLAY) then
if ($HOST =~ super*) then
if (! $?XAUTHORITY) then
alias su '/bin/sh -c '"'"'XAUTHORITY=${XAUTHORITY-$HOME/.Xauthority}; export XAUTHORITY; exec /bin/su \!*'"'"
endif
else
alias su '/bin/sh -c '"'"'cp ${XAUTHORITY-$HOME/.Xauthority} /tmp/.Xauthority.$USER; XAUTHORITY=/tmp/.Xauthority.$USER; export XAUTHORITY; exec /bin/su \!*'"'"
endif
endif
I guess I should have folded the lines, but it's such a pain in csh...
