Re: Cygwin 1.7 beta XWin Crashs from Ubuntun 9.10 after Firefox sessions (update)
After I upgraded to xorg-server1.7.3-1, XWin does not crash anymore after I ssh to Ubuntun 9.10 invoking gnome-session. But it hangs intermittently after a few Firefox sessions and I need to terminate XWin. Hope the next xorg-server upgrade will improve this. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/

Re: Cygwin 1.7 beta XWin Crashs from Ubuntun 9.10 after Firefox sessions
Hi Jon, further testings show the issue is related to GNOME. XWin still crashed after I started GNOME-SESSION and waited for some time without bringing up any apps. I',m able to ssh to the Ubuntu box and bring up xterm or firefox and do some work without any problems. Since you can't even start up GNOME-SESSION, I am not going to pursue this issue anymore. Hopefully future upgrade will fix this problem. Thanks for your efforts.

Re: Cygwin 1.7 beta XWin Crashs from Ubuntun 9.10 after Firefox sessions
Thanks for the backtrace.
It's interesting, but I'm afraid it doesn't immediately let me pinpoint the
problem.
A couple of questions I should have asked before:
- is this crash caused by to doing some specific action or looking at specific
pages in firefox?
- using ssh with your X server in a window but no WM is rather strange. Are
you starting any other programs or a window manager along with firefox? Do you
see the problem if you start the X server with -multiwindow? Do you see the
problem if you use -query to do an XDMCP login?
In future, please send your replies to the cygwin-xfree list, rather than to
me personally.
