environment problems mixing mintty and xterm

environment problems mixing mintty and xterm

[Lester Ingber]

I find mintty very useful.  I can bring it up as a standalone window or I
can run run additional windows from xterm running under X.  If I do the
latter then mintty inherits the environment from the xterm window I'm
running, e.g., including additional path entries set in ~/.tcshrc, etc.

However, if I run mintty from my xterm window I have some problems.

For example, say I have open xterm (from startxwin.csh) with
xterm +tb -j -sb -geometry 80x84-6+0 &
this sets LINES set to 84.

If I have set up .minttyrc with
Rows=100
then after I go to my mintty window and back to my xterm, my xterm window
is messed up, e.g., top rows under `less` are off the screen.

There is no such problem, when running xterm, if I open an additional
mintty window as a Windows shortcut since it seems to open independently
-- without taking on the environment variables in my xterm window.

I guess it probably would increase the minimal nature of mintty to restore
such environment variables when leaving a mintty window?

Thanks.

Lester

Thanks for the problem report, although I'd prefer to get these via the 
issue tracker at http://code.google.com/p/mintty/issues/ .

Unfortunately I haven't been able to reproduce the problem. A Unix 
process only receives copies of its parent's environment variables and 
it cannot change the originals, so the problem isn't caused that way.

Window size changes are signalled to the child process through a call to 
ioctl() on the child's pseudo terminal (pty), which triggers a SIGWINCH 
signal in any processes controlled by that pty. Perhaps something is 
going awry there.

Does the LINES variable in the xterm change immediately after invoking 
mintty, when you change mintty's size, or only after exiting it? What 
command line are you invoking mintty with?

Nedit text plane inoperable.

[WEEBER Bill]

Hello,

I've been successfully using Nedit on Cygwin for several years.  Today,
I did a fresh Cygwin install and Nedit no longer works properly.

Now Nedit starts up just like it always did in the past, but the text
plane is inoperable. I am able to read the document, and the document is
not in read only state.

When I click on the text plane, nothing happens. Normally a cursor would
appear. 

Menu items popup when I click on them, but I cannot type characters in
the dialog boxes.

When I swap my cygwin directory with a previous install, everything
works fine.

I'm using the following:
	Xming (6-9-0-31) as my X server
	Windows XP Professional SP2

Anyone else experiencing these problems?

Thanks,

   -Bill

Try the the cygwin-xfree list.
