Hi,

I downloaded the latest version (2.510.2.2) of setup.exe from www.cygwin.com 
the other day, and installed it along with several packages. When I tried to 
run commands from the bash, I had some problems (e.g. that the path variable 
was not correctly set). From the FAQ I found out that setup.exe was supposed 
to create the file "etc/profile", but for some reason this had not been done - 
the file did not exist. However, I did find the 
file "/etc/defaults/etc/profile" which I copied into the "etc/" folder. After 
having done that, cygwin now works fine for all purely text-based purposes. 
However, when I try to run anything that demands a graphical display, e.g. 
xterm, I get the error message:

xterm XT error: Can't open display:
xterm: DISPLAY is not set

I'm guessing it might be the case that setup.exe was supposed to create a file 
which sets DISPLAY when the bash is started, but that it did not for the same 
reason that it did not create the "/etc/profile" file, whatever that reason 
was. I have tried to experiment by creating a DISPLAY environment variable and 
giving it different values I've seen used in other places (e.g. :0.0), but to 
no avail - the bash then instead complains that it can't open that display. I 
have also tried re-running setup.exe, but that did not help either.

Thus the most simple formulation of my question would be: How should I set 
DISPLAY so that the programs demanding graphical displays will work?

If this question is not possible to answer because the correct value depends 
on some factor or the other, my question is instead: Was setup.exe supposed to 
create a file for setting the DISPLAY variable, and if so, is there any simple 
way to aquire this file?

I use WinXP, in case that's relevant.

Thanks,

Markus
