Because the default options in the distribution provided
startup script changed to a more secure setting, consistent with
upstream changes and the general atmosphere of security paranoia that
is gradually eroding usability (as security issues get alot more
attention than usability -- so much so, that while a benefit of computers
was that they could adapt to the user for a friendly user experience,
the opposite is becoming the standard. I.e. users are expected to
adapt themselves to the changing machine programs.
I start my X server on login -- which means it has to work
when called at login -- and I wanted to make sure I could pass
custom arguments for the font path (among other things). As
a result I simply "wrote my own" startup script that has it's
own defaults. I expect it to work until some argument I expect
to be there is deleted.
I don't instantly get new features and benefits that might
be invoked from the distribution script, but usually it starts, and
every once in a while I review it and the cygwin start scripts to see
if there is something I should change. But at least I don't get
caught by this particular problem.
I *do* still get caught by the installer overwriting
Windows mount points with physical directories which causes
various programs to stop functioning until I move the updated
files to the 'mount-point' and change the physdir back to
a mount point.
Anyway, ---
The script is started by a shortcut in:
C:\Users\<YOURUSERID>\AppData\Roaming\Microsoft\Windows\Start
Menu\Programs\Startup
That has a shortcut to 'bash' with arguments:
(Target:) C:\bin\bash.exe -c '/bin/setsid "%USERPROFILE%/bin/startxwin.sh"'
(Start in:) %HOMEDRIVE%%HOMEPATH%
(Run:) Minimized

It is also an icon on my 'Quick Launch' bar (i.e. in directory):

--------------
This is most likely due to a major rewrite of the xinit package which
contains all start-up scripts.

Not if you write your own -- then you will get your own
"customized" behavior (so at least when it breaks, you have a
chance to fix it yourself)...
If you don't like mine, fine, copy the cygwin script and make the
changes to it and call it the same way. At least you'll get whatever
behavior
you want and upgrades won't be altering your script...
BTW, Laurens Blankers, the opensource model for developers doing their
own thing is called a "do-acracy". Those that do, make the rules. Not
saying it is a great thing, just putting a handle on it... ;-)
