cygwin Xserver losing connection

0

I am running Xserver on cygwin (on top on Windows 7), and then using xterm to remote to linux via ssh -X, and run remote applications there, like konsole, emacs and others.

Initially all works fine, e.g. executing emacs pops up the correctly working window on my Windows 7 box.

But if I try to run the same emacs some time (like an hour) later, I get a linux message Display localhost:10.0 unavailable, simulating -nw and emacs runs in-line.

I have checked and the Xserver seems still up and running ok. Indeed, if I exit out to the original cygwin and reconnect to Linux by ssh -X again, it works just fine.

Would you know what is happening and how can it be fixed? Why is my Xserver connection being dropped?

Thank you very much.

Is it just emacs,or do other programs show this problem? Are you sure Xserver is still running? – Isaac Rabinovitch – 2012-10-25T05:41:52.543

@IsaacRabinovitch Other programs have the same problem, like konsole, for example. I'm sure Xserver is still running -- like I wrote, logging out from linux back to cygwin and connecting again via ssh -X allows to run everything ok, supposedly on the same Xserver... – gt6989b – 2012-10-25T14:43:43.067

Feel like a total moron to ask a question and answer it myself, but for the same of a future reference, here is a work around that helped. Instead of using ssh -X, if ssh -Y is used instead, it works better and does not drop the ability to spawn new windows over time.
