Re: Xdmcp too slow with SOME Linux accounts.
I have retested this with connections to different Linux systems, and it (my xwin server hang) appears to be isolated to a single Linux. I find there is a difference in Fedora versions on the two systems. Although I'm surprosed that the version of Fedora would cause my local xwin.exe to stop reading the windows message queue, I will ask the system admin to look into this from a Linux config standpoint. -- 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: Xdmcp too slow with SOME Linux accounts.
Michel, One alternative you could try is ssh-ing to the host you want to run the programs on and invoking the programs directly and comparing the graphics-update performance. In essence this means issuing the following command: ssh -Y [EMAIL PROTECTED] program The 'Y' parameter is very important, don't forget it. All this hinges on whether or not the host has SSH enabled, and if it does, it must also have X forwarding enabled. Still, it won't cost you that much to try. In the past, I have tried to use xdmcp like you have only to encounter the same sluggish performance you've reported, so I've opted to use X tunneling over SSH instead, which works great. The IS a drawback though, it doesn't give you the full desktop with the background and everything you might be looking for, but in practice the things you really want are the apps, anyway.

Thanks for the tip. I was able to use the ssh, but that generated errors on the console (below). Before running the ssh command, I started xwin, but perhaps I need to specify some options?

Re: Xdmcp too slow with SOME Linux accounts.
Michael, I am assuming you are invoking the ssh connection from a graphical xterm window, it won't work from a console-mode bash prompt. Other than that, it might mean that X forwarding is not enabled on the host you are connecting to. For the record, I just tried the scenario I outlined; ssh to a host and then invoking eclipse. It worked for me, so it has to be a configuration issue on your setup. J On Wed, 2007-09-12 at 07:45 -0700, Michael Giroux wrote: Thanks for the tip.

Re: Xdmcp too slow with SOME Linux accounts.
Have been watching this for a few days now and here is what we see. When I start an XWin session, response is excellent for about 1 minute. If I happen to close the XWin server in my cygwin desktop while the response is really good, I get a warning dialog that there are 4 clients connected. Repeat the test, start XWin, open Eclipse, use system until response degrades. Now close the XWin server while the response is poor. This time, I get a message box indicating that there are 17 clients connected. My network admin is seeing sessions connecting from the Linux box into my XWin server confirming that there are sessions being initiated on the Linux system. From this, it seems the response issue is somehow related to these clients. Since I'm only starting one client (Eclipse) the others I have no way of knowing what the others are. To test the theory that this is the cause of the problem, is there any way to prevent these clients from starting and connecting to my XWin server?

Make an addtional connection with ssh and make ps print all processes for your account. Or ask someone who is root to do so. To test the theory that this is the cause of the problem, is there any way to prevent these clients from starting and connecting to my XWin server? Yes. But these clients get started by the login process on the unix/linux computer so we would need to know exactly how you connect and start eclipse for further advice. -- 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: Xdmcp too slow with SOME Linux accounts.
I got a little help from my network admin. We started watching the traffic between my Windows desktop (XWin server) and the Linux box (client). What we see is interesting. When I start XWIN and then launch Eclipse, response is perfect. If I move the mouse, my system sends a message to the Linux box. When I see the performance problem, what I see is that if I move the mouse, nothing is sent from my system to Linux. The Linux box sends a keep-alive or something to my system every 15 seconds. When that happens, it appears that a mouse message is sent to Linux. To make matters a bit more interesting, the problem seems to occur shortly after I do something that effects the application windows on the XWin desktop. For example, if I start XWin, then start Eclipse, response remains good until I do almost anything to window. If I minimize Eclipse, I notice that shortly after that, my system stops sending messages to the Linux box when I move the mouse. Or, if I create a terminal window, then close it, the same happens, ... shortly later my system stops sending messages to the Linux box. Once this occurs, the only resolution is to abort XWin via the windows task manager (because it is not responding to mouse events) and restart it. All of this leads me to ask if maybe I have XWin installed incorrectly or maybe have the wrong version. Does any of this sound familiar to anyone who has used XWin for more than a few releases?

Re: Xdmcp too slow with SOME Linux accounts.
Thanks -swcursor has eliminated the console messages, and it manages to highlight the extremely slow response. It is taking several seconds for the mouse pointer to move when I move the physical mouse. In fact, I now realize that keyboard is non responsive as well. I'm not seeing any cpu utilization on either system, which gives me the feeling that there is a loop somewhere looking for events and the loop is using a timer or something. Using GUI on the physical Linux box does not have this problem, so I keep guessing that it has something to do with TCP/IP buffering or polling. Guess I'll have to ask a network admin to monitor this connection to confirm or discard that theory.

Re: Xdmcp too slow with SOME Linux accounts.
I have a similar problem, but it is not limited to a specific account. In fact, it is fairly random. Sometimes I get pretty good performance, and then it just dies. In my case, it seems to get pretty bad when I launch Eclipse, but I have to admit that Eclipse is the only GUI app that I use, so it may be gui apps in general. What I see (reported in another message) is that mouse click and keyboard seem to be very responsive, but mouse move is non-responsive. If I open a menu and move the mouse, the menu items are not highlighted. If I move the mouse several more times over the menu, ultimately a menu item is highlighted. Once it is highlighted, I can click to select the item. From a pretty uninformed perspective, it appears that mouse move events are not being forwared from my server to the client, but I'm not sure how to determine that. I am pretty confident that the problem is limited to mouse move events, and that keyboard and mouse click events are being forwarded immediately. I've seen nothing on my other post.
