Narrowed this down some. Posting for future Googlers. Looks like the culprit is probably
What's new and what changed from 1.7.7 to 1.7.8 * Drop support for Windows NT4 prior to Service Pack 4. per http://cygwin.com/cygwin-ug-net/ov-new1.7.html Looking at the NXWin log output I get the feeling it's depending on some old filename semantics. First bit of strangeness is that the output of NXWin should go to 'winlog', but in the post 1.7.7 secnario its written to 'svclog', which is intended for the parent of NXWin. The place where NXWin breaks down is Dispatch: Exiting from the dispatcher with exception [2]. also this seems particularly not good Error: Cannot rename 'C:\Users\username\NX73F8~1/D-W2K8NXCLIENT-85AF85472A34ED995AD4DFCD5F3BEFBD' to 'C:\Users\username\NX73F8~1/T-D-W2K8NXCLIENT-85AF85472A34ED995AD4DFCD5F3BEFBD'. Error is 'Permission denied' In case it's relevent, have 'fstab' setup like so none /cygdrive cygdrive binary,posix=0,user,noacl,auto 0 0 It's a guess, but I'd say that NXWin might require work to eliminate some obsolete file semantics. On the other hand the issues could all reside in the X server code and simply recompiling and relinking NXWin in the latest X11 tree will make it right. Till then the 1.7.7 DLL does the job. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
