problems starting xterm

problems starting xterm

[Markus Hoenicka]

Hi,

I've set up Cygwin 1.7.1 lately, along with X and some applications.  
The X server works ok and claims to be "Version 1.7.5 Build Date:  
2010-02-05". I can run Emacs as an X application without hassles.  
However, when I start the X server, or when I try to run xterm from  
the X server systray icon, xterm apparently fails to find a shell to  
run, so it terminates (no pun intended) after a couple of seconds:

xterm: Could not exec 4.90.2.20040617: No such file or directory

I have plenty of shells installed (bash, ash, dash), and they work ok  
in MinTTY. I'm afraid I'm missing some simple but important setting  
somewhere. Any ideas?

regards,
Markus

what happens when you call xterm from the mintty command line?

$ xterm Xt error: Can't open display:

Do I have to set DISPLAY manually? And if yes, what should it read?

For the mintty test case, yes, you need to set DISPLAY.  Use this:

export DISPLAY=:0.0

Yep, that works, except for the following warning:
Warning: Missing charsets in String to FontSet conversion

As this method to start xterm seems to work, do I have to start the X  
server some other way than I do now? I just use the Win start menu  
entry Cygwin-X->XWin Server.

thanks

I can answer that one myself. Running startxwin from mintty works  
without a hitch. This is no big deal for me, but this still leaves me  
wondering why one of the officially recommended ways to start X (as  
per the docs, see  
http://x.cygwin.com/docs/ug/using.html#using-starting) fails on my  
system.

regards,
Markus

Does your CYGWIN environment variable contain tty?

Google suggests '4.90.2.20040617' is a novell netware client version.

So, erm... yeah.

Good catch. I use a Windoze client on a Netware network at work, so
this client is likely to be installed. But then, why would xterm try
to run that client???

Administrator@pc51997 ~
$ echo $CYGWIN
server

Which, in fact, is a leftover of 1.5. But no, there is no tty here.

Actually it's trying to invoke that client's version number as a
program, which is even more weird. There are only three places that
could come from: the SHELL environment variable, the /etc/passwd file,
and a -e option on xterm's command line.
