Actually the authorization checks in XServer is per user.
IF you start Xvnc with -ac option then it will disable authorization checks,
which is equivalent to xhost +
There is one more convoluted way of doing it without -ac option by using
xauth command.

I get the same thing connecting to a linux box. I just do an xhost + when I
first connect, & it will let me open gui's after I su - .

Subject: Unix $DISPLAY env variable
Hi,
I have run into a problem with my VNC server that I run on Unix.
If I su to another user and I want the users environment I use the command
"% su - username".
This asks me then for that users password and sources that users env
scripts, etc.
The problem is that my DISPLAY variable does not get set. And if I set the
display variable to one of the following (assuming that the server was
assigned :1 as it's display number):
hostname:1.0
:1.0
:1
Then I get something like: "xterm Xt error: Can't open display: :1" etc. If
DISPLAY is not set then of course I can't open any Xwindows. And
interestingly enough if I set DISPLAY to hostname:0.0, it opens the window
in my root display (Not the VNC client). It would be fine if I could fix
this using xhost, but I didn't change hosts, just userid.
So, my question is.. How do I have to set my DISPLAY env variable to open X
windows if I change my userid? Setting it to the same thing as other windows
in my client have (hostname:1.0) does not work unless I am that user. Is
this some type of security feature, or is it a problem that no one has run
into yet?

BTW- VNC is very cool. I am using it to work from home with my ADSL
connection and find the delay tolerable. I suppose using Xprotocol (like I
expect Exceed does) would speed it up, but then you probably lose the "same
display from anywhere" feature. I am looking forward to trying x2vnx.
