Re: X server crash when running texworks

1. Install texworks-0.4.3-1 from Cygwin Ports.

2. Create two tex files in your home directory, say test1.tex and
test2.tex. I don't know if the contents matter, but in my case both
files contain the following:

\documentclass{article}
\begin{document}
Hello
\end{document}

3. Start the X server by using the Start Menu shortcut.

4. Start texworks by typing texworks in an xterm window.

5. Click on the Open icon to open one of the tex files. Then do the
same to open the second.

At this point the X server crashes and gives the message Caught signal
11 (segmentation fault). Server aborting.

Before the crash I get the following warning in the xterm window when I
open a file:

QFileSystemWatcher: failed to add paths: /home/kbrown

I don't know if this is significant.


Confirmed, cause unknown.  It might be a couple of weeks before I can 
get back to this.

Re: Cannot launch ssh from X11 system tray icon

2012-03-28 Thread Craig
I don't suppose anyone has any thoughts on this?
It's rendered Cygwin X11 unusable. :-(
Can any further diagnostics be enabled?

 I have two machines, a desktop and a laptop.
 Both are 64bit Windows 7 Enterprise installations.

 I (think I) configured Cygwin on both the same and they have the same
 identical ~/.XWinrc file.
 They both use the same mirror for installing and are both fully up to date.

 A précis of my .XWinrc looks like this:

 menu root {
 // Comments fit here, too...
 Xterm exec xterm
 Xterm - Vulpix exec ssh vulpix xterm -e bash --login
 }

 And on the desktop both work and on the laptop only the local xterm will run.
 Nothing appers in /var/log/anything

 So I added an entry like this:

 Experiment exec ~/experiment

 and ~/experiment looks like this

 #!/bin/bash
 (
 set -x
 ssh -v vulpix xterm

 It still fails (i.e. does nothing) and /tmp/experiment has

 On the off chance this is a known issue, would you mind downloading the X
 server symbols and getting a backtrace using the instruction on [1], before I
 try to reproduce it.
 
 OK, the backtrace is attached.

Thanks very much.

I'm afraid I can't reproduce your issue, but looking at the backtrace and the
somewhat intermittent nature of the fault, I think perhaps this crash is
caused by a race condition which exists in the conversion of the window icon
from an X property to a Windows icon.

I've uploaded a snapshot with some fixes for that at [1], perhaps you could
try that out and see if it helps?

Yes, that seems to fix it.  I just started texworks and compiled 6 or 7 
tex documents without a crash.  I've never been able to do more than 1 
or 2 before.


Thanks!

Hello Craig,

you have to use X11 Forwarding. Try

menu root {
// Comments fit here, too...
Xterm exec xterm
Xterm - Vulpix exec ssh -Y vulpix xterm -e bash --login
}

or

menu root {
// Comments fit here, too...
Xterm exec xterm
Xterm - Vulpix exec ssh -X vulpix xterm -e bash --login
}

Dirk

 Hello Craig,

Hi Dirk,

I am sorry I wasn't more explicit. My ssh config file enabled X11
forwarding, as you'll note

debug1: Requesting X11 forwarding with authentication spoofing.

was in my original post.

I added -Y to the ssh and still saw both the X11 debug1 line and the symptom.
