This may in fact be a general cygwin problem rather than xfree. What we are finding is a change in general process handling. During our original testing - on windows 7 32-bit - we tested scripts we had developed under XP that prompt the user for information about the server, login, etc. and then start the x server and invoke the cygwin xterm or mintty to perform an ssh -Y to the server as the login specified. The code looked at the processes, identified whether or not the server was running, and, if not, launches a new server. Otherwise, the code skips that step and goes on to start the terminals. After testing, a deployment decision was made to move to windows 7 64 bit instead. We assumed that everything would continue to work as tested. What we are seeing, now however, is that we are getting multiple X servers started. Even worse, we are seeing processes like bash, ssh, mintty, and xterm hanging around aft</pre> Larry W.

It provides DEC VT102 and Tektronix 4014 compatible terminals for programs that can't use the window system directly.

I installed it there, but the crash still occurs. The backtrace produced is quite huge - and less useful because X didn't have any of the debugging symbols in it. here is a bit of what we are seeing. We start up the X server. It is configured to use xauth. We start up a mintty session and an xterm session. We ssh from these windows to our SPARC Solaris 9 work machines. We start up, in each window, an in-house written binary application which makes use of the Tk C libraries. If we run just 1 mintty, or just 1 xterm, that works. If we run one of each (which the developers do due to various features, etc. they wish to leverage), we often - not always - get an error of the following nature.

Thank you for pointing it out. Now by doing xset fp+ $(cygpath -w /usr/share/fonts/100dpi) the nedit messages about missing fonts are gone! Thanks for helping!

If your Xming installation is on the same computer as your Cygwin installation and the latter is under C:\cygwin, your command xset fp+ /usr/share/fonts would translate to something like xset fp+ c:/cygwin/usr/share/fonts The actual format expected by Xming might differ; see the output of xset q for its font path. You might need to experiment a little. Additionally, if I remember correctly, each directory containing a fonts.dir file must be specified in the font path explicitly (i.e. the directories in the font path are not searched recursively). So the font path extension you need is possibly rather something like xset fp+ c:/cygwin/usr/share/fonts/75dpi,c:/cygwin/usr/share/fonts/100dpi Horst </pre> Kiehl, Horst 2012-05-21T15:30:28 http://permalink.gmane.org/gmane.os.cygwin.xfree/22454 <pre> Update: Yaakov, I just found out that you were right in your assumption that there *is* at least one part in the nedit user interface which DOES use preset fonts (which can't be changed): It's how the file names are rendered in the "open file dialogue". So this indeed explains the warning I get. What still reminds to do is to install the missing fonts properly - see my previous posting to see what I attempted for this task. Ronald </pre> Ronald Fischer 2012-05-21T14:49:37 http://permalink.gmane.org/gmane.os.cygwin.xfree/22453 <pre> True, but this does not apply here (I think), because I when I instruct nedit to use specific fonts (those which are installed on my system) for the interface, nedit indeed uses these fonts, but still displays the error message. Meanwhile I found something in the Cygwin/X FAQs about this problem (I had overlooked it the first time): This seems to be a well known problem with some X applications, and it was recommended to install certain adobe fonts via Cygwin setup. So I run setup again to install the required fonts, and also (via xset) did a refresh of the font path. The problem still persisted. Looking at the installed fonts, I found my fonts being present only in /usr/share/fonts/100dpi and /usr/share/fonts/75dpi as a bunch of gz-files. I'm not sure whether this is correct (i.e. whether the X server is supposed to unpack them on demand), or whether the Cygwin setup script is supposed to do this. I think it is the latter, because when I did a xset fp+ /usr/share/fonts I got the error message xset:</pre> Ronald Fischer 2012-05-21T14:41:41 http://permalink.gmane.org/gmane.os.cygwin.xfree/22452 <pre> I just noticed that latest xorg-server-1.12.1-1 is crashing when using octave with fltk interface.

Actually, I thought that fonts are independent of the acutal implementation of the X-Server. I now see that I was wrong. The question remains, why nedit looks at *those* fonts. I'm perfectly happy to specify in the preferences of nedit only those fonts which are actually installed with Xming. However, nedit seems to look at certain fonts, which I certainly have not mentioned in my preferences.... Ronald </pre> Ronald Fischer 2012-05-20T10:07:30 http://permalink.gmane.org/gmane.os.cygwin.xfree/22449 <pre> In fact, it is. nedit, like other old Motif (and Xaw) applications, depends on server-side fonts. (Modern GUI toolkits, such as GTK+ and Qt, use client-side fonts via fontconfig or a wrapper thereto.) Therefore, you must install fonts where Xming will find them, and hence this is not an issue per se with nedit or Cygwin/X.

I think nedit must have a reason to look for these fonts which I have never specified somewhere .... As far I can see, Xming is not involved here (and I just mentioned it in *case* it is important). Basically, I could imagine two approaches to solve this: Either tell nedit not looking for these fonts, or installing these fonts in a place that nedit can find them. In both cases I don't know how to do it; that's why I posted it her. Posting it to a Xming forum doesn't make that much sense (I think), because the response there would likely be "This is not a support forum for Cygwin"....
