Re: problems with XFree

[Tom Bozack <bozackt1 at ridgecrest dot ca dot us>]

I think Cygwin/XFree86 is a great product  -- but there is nothing so 
good that it can't be improved.  I agree with all of you comments, 
although I haven't had the system reboot experience.

One persistant problem that you didn't mention (manybe you haven't run 
into it yet) is a very persistent and repeatable lock-up when used to 
login to another host using XDMCP.  The symptom is of a sudden large 
memory leak after 15-30 minutes of use.  XFree86 becomes unresponsive, 
system memory and swap resources are rapidly used up, and finally 
XFree86 crashes with a seg fault.  This also happens immediately (you 
don't have to wait 15-30 min) when you logoff the host and login again. 
 I've experienced this under Windows 98/98SE/ME.

For me this is a showstopper since it makes Cygwin/XFree86 unusable as 
an X server platform.  It's fun to play with, but this "bug" makes it 
unacceptable for routine use as an X server.
