Remote Desktop, MultiWindow & Cursors

[Wilks, Dan]

Looks like the newer versions of XWin are having cursor problems when
coming out of remote desktop (XP Pro).  After a remote desktop session
the cursor completely disappears in the X window client area.

Here's what I'm seeing:

- Run a cygwin bash shell
- XWin -multiwindow -clipboard
- Run xterm on a Linux box w/ PuTTY tunneling X.
- Move the cursor around the xterm.  Nice I-Beam.
- Go to another machine, remote desktop in.
- xterm is still active app but cursor is now outside the xterm 
  window over the windows desktop but with X's X cursor.
- Move cursor around.  It remains the X cursor wherever you
  move it.  Verify.
- Activate a Windows app (IE) and then back to xterm.  Cursor
  returns to I-Beam and proper behavior.
- Shut down remote desktop.  Return to tty.
- Now when the mouse moves over any X window it completely
  disappears.

Also, at this point, copying anything will completely crash XWin.  I'm in
the
process of looking into it.  My debug build of current sources doesn't
exhibit this behavior.  I'll try a non-debug build next.  Hey, is there a 
safe, automated, way to do a full, clean build of just Xserver?

XWin 6.7.0.0-7 with -clipboard hangs with cygwin1-20040422 in Win98SE

[Carl Holmberg]

Hi,

I am seeing the same XWin hang problem with the latest code, 
with -clipboard, as I've reported before.  In this case I also 
used the default startxwin.sh with a --logverbose 255 to try to 
pick up whatever logging I could.  This is a -multiwindow 
config, but identical hangs occurred before when running without 
this option, using twm instead.  Am running bash.   

My cygwin installation is up-to-date as of 4/28/04 12:28 EDT.  A 
cygcheck -csvr is available - I'll post it upon request.  In 
this case I also used the latest cygwin1.dll snapshot, but the 
hang occurs with the latest release cygwin1.dll also.  

I attached to XWin with strace using after the XTerm came up, 
stabilized and the XWin.log stopped producing initial output.  I 
then placed the cursor in the window, typed the "date" command, 
then copied (left click/hold/drag) and the pasted the command 
successfully.  I then left clicked to the left of the date 
command, right-clicked to the right, and XWin froze up.  As is 
typical, in my experience, only a few mouse clicks - 
particularly anything using the right-click, causes XWin to hang 
up completely with -clipboard.

The last 132 lines of the strace are reproduced below.  After 
that, I've included the XWin.log.  I've marked the place where 
the system froze (just before the kill -9 was issued).  Note the 
readv errno 11 returned 14 lines before the freeze point.

I hope this helps.

###Last 132 lines of strace.  Whole trace from time XTerm came

Instaling IRAF

[Marcus Vinicius M.Fernandes]

Hello

I've just intalled the Cygwin im my laptop and it's working well. But I'm an 
astrophysic and I would like to install a software named IRAF 
(http://iraf.noao.edu/iraf-homepage.html). This is a RPM. But the instalation 
does not proceed, showing messages about missing packages. The setup-
2.4...rpm is one of them.

Could you help me to install the IRAF software?

Thank you.
Marcus

Ps: The IRAF is easily installed under any Linux operating system.

Re: default configuration not working

[Sara Gamble]

Hi Alexander,

Thanks! I stumbled upon that last night after figuring out I was confused
about what -multiwindow window ment (I didn't realize it precluded having
a large background window).  Now I can successfully open an x-term in non
multiwindow mode and fix my display problem with 

startx -- :1 
and then from that xterm run either twm & or openbox & and get the
environment I want.

Thank you so much for helping me out with what was probably a really
simple question!

XWin gets the cookies

There should be atleast one READ in the 3rd column

Hello !
I'm trying to use Cygwin instead of installing a full-size Linux.
My task is learning system programming in Unix environment.
Unfortunately, I do not get "man" for some C/C++ functions,
such as "fork()", "cout", "getcwd()" etc. 
Other C functions (printf for example) are documented.
Where can I download the missing man pages ?
Thank you,

This is normal too. You can not run XWin in multiwindow mode and have an 
external window manager. You can either use -multiwindow or windowmaker.

This is the reason I refuse to use MySQL on Windows - sooner or later the 
multiple cygwin.dll problem that their distribution creates if the user also 
installs Cygwin is going to start biting people.  If possible I would suggest 
looking into Firebird (the database) instead.

Re: mysql command line client hangs in cygwin xterm

[Richard Piper]

On looking into this, it seems that mysql including its client is 
compiled with cygwin. It is an old version, and this may explain the 
problem.

I will look into this further, when I get a chance to download the 
"beta" version of mysql, which I assume is compiled against a more 
recent version of the cygwin.dll.

Yeah, that was an interesting email.  It was nice to see that someone
agreed with my assessment of the problem.  It is always a relief to hear
that I do know what I'm talking about from people who don't quite know
what they are talking about.
As I mentioned, the easiest solution is to always use cygwin built
programs if you want to run a program on a cygwin pty.
The logic that there had to be a solution to this problem because it
affects so many programs did escape me, though.  I'd be very happy to
see someone find a way to fool programs into thinking they are running
on a console when they are using a cygwin pty but the fact that it is a
serious problem doesn't mean that there is automatically going to be a
solution to the problem.
