In case you don't know what I am talking about, here is the correct truss
output:
...
munmap(0xFE9E0000, 32768) = 0
access("/net/u/jes/.Xauthority", R_OK) Err#13 EACCES <--- This XXX
....
Xlib: connection to "write(2, " X l i b : c o n n e c".., 21) = 21
:0.0write(2, " : 0 . 0", 4) = 4
" refused by server
Xlib: write(2, " " r e f u s e d b y".., 27) = 27
No protocol specified
write(2, " N o p r o t o c o l ".., 22) = 22
root is not allowed to open ~/.Xauthority because it is mode 0600,
this is the problem with xscreensaver.
