XWin with "rootless" option crashes on Vista

[rincewind]

Hello All,

I had been using Cygwin with ICEWM on my XP box for sometime. I moved to ("asked" to move to) Vista recently and I installed Cygwin and compiled ICEWM on my box. My problem is that, I am able to run startxwin.bat with the "multiwindow" option, but not with the "rootless" or "fullscreen" option since XWin just crashes. I understand that files have been modified in the new Cygwin, so I stuck to making changes in the .bat file only. I tried running startx too, but not with much avail.

In short, running startxwin.bat with XWin-multiwindow starts the X Server and I am able to launch newer xterms. If I remove the multiwindow option altogether or change it with rootless (ideal for me since I want to run a different window manager) or fullscreen, XWin crashes.

I understand that there are a few applications that cause strange issues with cygwin and I seem to have one such on my box (Logitech's webcam package). I would be glad with any advice on this issue. I looked through the forums, but I haven't been able to find a thread that matches my problem.

Thanks for your time.

Regards,
Rincewind

Please try completely uninstalling the Logitech software, make sure
you're running the current versions of Cygwin and X11, and try again.
If that does not help:

http://cygwin.com/problems.html

In addition to *attaching* the output of "cygcheck -s -r -v", please
also attach the /var/log/XWin.0.log from the failed attempt.

Thanks for taking a look into my message. I have uploaded the relevant files (cygcheck and xwin.0.log). I am able to see some differences between the Xwin.log entries of successful (multiwindow) version and the failed (rootless) version. But perhaps they are directly related to the multiwindow and rootless options themselves.

Is there a way I could obtain a stack trace of the crashing process on vista ??

Thanks,
Rincewind

Your reply seems to be missing "I've tried uninstalling this and the problem
remains" :-)

To get something useful you'll probably want to use the unstripped binary I've
made specially for you at [1]

The instructions in the contributors guide [2] should clearly explain the
process of building the X server from source.

Rincewind>> For the record, Yes :-). I uninstalled the logitech drivers and I still see the problem. Thanks for the tip on how to obtain a backtrace. I am hoping to use the binaries you provided and obtain a trace. Thanks for your time.

Hi,

I was intrigued by this one, but could not reproduce.

In Xming I got a crash due in -internalwm mode due to a message handler
collision (WM_WM_MAP(2) was shared badly).
I fixed this by adding yet another handler, i.e. WM_WM_MAP3, to give
separation..
This is probably not related.

Thanks
Colin

Hello,

I was having the same problem, but using openbox. Basically, all options except multiwindow would crash XWin.

I was ready to quit on the problem, when it started working after an upgrade of the graphics adapter driver.

Maybe you can try it.  In my case I use an ATI FireGL 5200, on an HP laptop.

I hope this helps.
