Thank a lot for the inputs.
Just want to clarify some things:
* The version of X11 is: X11 Beta 3 - XFree86 4.2.1
* I am not trying to run any applications yet. Upon launch of X11 I get
the error message I wrote.
* When I login locally (that is I have an admin account that I have
created in the System Preferences when the mac was first installed, I
don't get any errors.
I have an Xserve with all my students put into NetInfo. When one of
these users which are located on the server and not on the local Client
machine, log in I get the X11 behavior described below.
I took a look in to NetInfo and looked att the different values in
there for the user with no problem and the user with problem.
I noticed that there was no "Shell" property in the non-functioning
users settings.
What I did then was that I entered a new property, called it "shell"
and I set the value to /bin/tcsh.
This made the whole thing work.
I don't know why this had occurred that there was no Shell entry for
the user, but this fix made it all work again.
Sorry for the trouble and thanks alot for your input.

Hi folks!
I have an Xserve 10.2.6 taking care of 306 student accounts for the
moment where the clients are eMacs and PowerMac G4s. Some courses will
soon be running X11 apps, therefore I installed the application on all
the client machines using ARD's Install package function.
When I then logged in as my template user to verify that the
installation had went ok and that I could run some X11 apps, I got this
message in the xterm window:
"xterm: Could not exec UID: No such file or directory". After 5 seconds
the xterm windows closes.
Does anyone have a clue what this could mean and how I could solve this
problem?
* I have tried to install the X11 application without ARD too, with
same result.
* I have also installed X11 on another Mac which wasn't cloned using
NetBoot and NetInstall, logged in as the template user, also with same
result.
* I have also logged in as a different user, but got the same result.
**** However when I log in locally to the client machine X11 works
fine.
It sounded like you had an actual problem, until I got to this line.
If it works fine when you log in "locally", how are you trying to log in
when it doesn't work?

xterm does this when it's trying to spawn the process to run in the
terminal:
execlp(ptr,
(term->misc.login_shell ? shname_minus : shname),
(void *) 0);
/* Exec failed. */
fprintf(stderr, "%s: Could not exec %s: %s\n", xterm_name,
ptr, strerror(errno));
(void) sleep(5);
exit(ERROR_EXEC);
so for some reason it's trying to run a program called "UID". How are
you starting xterm?

Hi,
I'm using an editor that runs on FreeBSD and OS X and uses Xft to draw
the text buffers. I got the impression that Xft drawing is
considerably slower on OS X. Actually, on a slow FreeBSD machine it's
not possible to see how the editor draws the text, while on a fast OS
X machine I can watch that closely. I don't know how to measure the
Xft performance exactly, so this is a bit wish-wash. However, since
there appears to be such a great difference I wonder if there might be
a technical reason for this. E. g. something like this: FreeBSD X11
uses hardware acceleration and OS x doesn't.
You'll have to more specific if you want a meaningful answer (i.e. what
versions of X11 are you running?, which version of Xft is the app
trying
to use? What is the program?)
