XWin too slow to start
For years I have been using fvwm2 and cygwin, but today it stopped working. The only way I could get it to work again was to insert a 'sleep 15' between: XWin -clipboard -rootless -silent-dup-error sleep 15 fvwm2 Without the sleep, fvwm2 actually executes first but has no X server to connect to. What is causing XWin to startup so slow ? -Steve More -- 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/

What is causing XWin to startup so slow ? Good question. What did you change recently? Certainly nothing in the X packages has changed for years, so you've either updated another Cygwin package which is causing you trouble or you've introduced an external change. But of course you realize that you're providing no mechanism that synchronizes X and fvwm, right? Regardless of how slow or fast the X server startup is, you've still got a potential problem there. That said, submitting a problem report may shed some light on your problem: Problem reports: http://cygwin.com/problems.html My WAG is that you've changed some network/firewall settings that are slowing down the X server startup. -- Larry Hall http://www.rfk.com RFK Partners, Inc.

( Could it have been an automatic update for XP ? ) I even re-installed cygwin from scratch to debug this issue. As I mentioned, the X stuff hasn't changed in years (as there is no maintainer - you want to be it?) so I would expect much help here. As for whether the auto update of XP could have an effect, the answer is of course! My WAG is that you've changed some network/firewall settings that are slowing down the X server startup. What type of network traffic is the X server trying ? Is it trying to do DNS lookups ? Is it trying to connect to a website ? X uses TCP by default for it's connections. 6000 is the common default port. You can change and/or disable that of course if you want (see the X server documentation).

Not really no. However, if you had not changed any Cygwin piece prior to noticing the problem, I think it's safe to assume that the delay is introduced by some external change, which is why I mentioned network and firewall possibilities. Depending on your source for A/V software, this is a possible culprit too. -- Larry Hall http://www.rfk.com RFK Partners, Inc. (508) 893-9779 - RFK Office 216 Dalton Rd.
