You are not alone. This is a known issue. Unfortunately I cannot
comment on when the fix will be available.

I installed Tiger this morning and now the scroll wheel on my mouse

for this mouse, it just worked; I'm not even using 3 button
emulation because the wheel is also a button.
Now I can't scroll a line at a time like I can with Panther, or in
any of my other applications. If I try to scroll slowly, nothing
happens. It acts like there is a speed threshold and only then will
it respond, by scrolling a bunch of lines at once and often all the
way to the top of the scroll buffer. There is no way to control how
much it scrolls, which is very annoying.
I've tried fooling with various settings in the mouse control
panel, but nothing seems to make a difference. Any ideas?

Short answer:
Todd is right. You should let ssh set the DISPLAY for you if you
don't know what you are doing. It will "just work" and will be
secure.
If you sometimes need to set DISPLAY for other reasons, we can
discuss
how to do so intelligently. E.g., you can test in your .cshrc
file to
see if SSH_CLIENT or SSH2_CLIENT is set, and if it is, don't set
DISPLAY yourself.
Not only do you NOT NEED to type 'xhost +', it is FOOLISH AND
DANGEROUS
TO DO SO! :-) Do not type 'xhost +' for any reason ever. That's
not
an overstatement. You have been warned.
Long explanation:
To understand the issues, you need to understand how all this works.
xlcients run on the remote host (here solaris). xserver runs on your
local host (here mac) and almost always listens to port 6000
You X11 server on your Mac is "listening" for X connections on port
6000 at your IP address. It will not accept connections from
unauthorized hosts, however. xhost adds allowable hosts. Anyone on
the host you name will be able to connect to your X server. xhost +
means "any machine." So when you do 'xhost +' (a very foolish
thing to
do, BTW), you are saying, "anybody who can see my machine, no matter
where or who they are, can use my X server." This is VERY DANGEROUS,
because using X11, people can do amazingly nasty things to you.
Do not
do it, ever.
DISPLAY is a host name and a number. The number is added to 6000 to
tell your xclient which port to try to connect to the host on.
This is
why most of the time you set DISPLAY to :0.0 The lack of a host name
means (sort of) "localhost" or "this machine". The 0 means "port
6000".
ssh makes a "tunnel," from the machine you connect to, to port
6000 on
your local host. The strange DISPLAY (localhost:10.0) you see is
telling your remote clients to try to use port 6010 on their own
machine. ssh has made a tunnel from 6010 on the remote machine to
6000
on the local machine. This tunnel is encrypted and very secure,
but a
slight bit slower. You should use it! Because of this tunnel,
you do
not need to type 'xhost +'. However, I have found the need sometimes
to say 'xhost localhost' or 'xhost 127.0.0.1' on occasion, to
allow the
local end of the tunnel to work its magic.
BTW, it certainly does work to set DISPLAY on Tiger. I think the
issue
might be with VPN. But I don't care; you should use ssh and I'm not
going to tell you guys how to do dumb things. :-)

Hi Jean,
Something strange is going on with DISPLAY since X11 version 1.1
and
Tiger. It’s causing me problems.
One thing I think you need to do is take the command out of your
.bash_profile that sets DISPLAY. It makes sense that DISPLAY
should be
set to your ip address but it does’nt work anymore.
ssh sets DISPLAY automatically. For me, it sets it to localhost:
10.1.
I don’t know why but it works.
Another post said you don’t need to type ‘xhost +’ before you do
ssh.
Regards,
todd

Subject: Help: X11 (Tiger) and Solaris 9
Greetings,
I have a very bizarre problem with X11 and Solaris 9. I would
appreciate it if you could help me resolving it. Here's the
scenario:
I have an iMac G5 running the latest Tiger. I installed X11 and
Xcode
(even the latest as of this morning) and I connect to this network
from home using Cisco VPN. On the other side, we have installed a
new
Sun v240 dual procs, 8 GB RAM, running Solaris 9. The only
application
running is HP OpenView Network Node Manager 7.5 and this is the app
that I need to access using X11.
After typing "xhost +" on my terminal, I connect to the Sun box
with
the command line: ssh -2 -Y devicename -l myname
At that point, I receive this warning message:
Warning: No xauth data; using fake authentication data for X11
forwarding.
Last login: Tue Jun 7 10:05:48 2005 from 172.21.127.233
Sun Microsystems Inc. SunOS 5.9 Generic May 2002
In my .bash_profile, I have setup the DISPLAY for my static VPN IP
address. So, now I call my app with "ovw &". After a few moments,
the
Sun replies:
Error: Can't open display: 172.21.127.233:0.0
Sometimes, it works fine. For example, this morning, I loaded my
application without any problem and used it for several hours
until I
logged out. And now it does not connect anymore.
I thought that it was the bandwidth through the VPN, but after
checking on our Concord eHealth, the VPN is working normally without
excessive utilization (below 50%). We also checked the router
downstream of the Sun box and all looks normal.
What do you think that the problem might be?
Thanks in advance for your replies.
Best regards,
Jean M. ('Jay') Feuillet
