Oh, well. I can think of 2 possible issues/solutions: With XDMCP under VcXsrv or Cygwin XWin, you often need to use this argument to, usually when you have multiple (virtual) network adapters: -from 192.168.0.20 XDMCP involves a forward-confirmed reverse DNS lookup. So if you have incorrect DNS records like the following: PTR: 192.168.0.20 - windows-pc A: windows-pc - 192.168.178.20 Then this problem will happen. -Mike -- 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/
[ANNOUNCEMENT] Updated: xorg-server-1.17.1-2
The following packages have been updated in the Cygwin distribution: *** xorg-server-*1.17.1-2 These packages contain XWin and the other X.Org X11 servers. The following cygwin-specific changes have been made since 1.17.1-1: * Fixes for regressions caused by RANDR change in 1.17.1-1 Addresses: https://cygwin.com/ml/cygwin-xfree/2015-02/msg00032.html * Add marketing name for Windows 10.0 * Log the locale when it's not supported by libX11 * Log windows thread ID on fatal signal to aid in interpreting crash reports NOTEWORTHY CHANGES IN 1.17 == The creation of indirect GLX contexts is now prohibited by default. The +iglx option is required to allow them. See [3] for more information on possible OpenGL configurations. '-nolisten tcp' is now the default, so the server only accepts local connections on a unix domain socket. A '-listen' option has been added which can be used to restore the previous behaviour. x86: c1627dff7c676a226e8030b63539c8d5 *xorg-server-1.17.1-2-src.tar.xz e9a7f22b6372d5bc223d6c98c4e8d3b3 *xorg-server-1.17.1-2.tar.xz 76c0622cbf4d6de6ddb6acc4365a4dcd *xorg-server-common-1.17.1-2.tar.xz 9c7ce33739bcea5276bf456431b04f81 *xorg-server-debuginfo-1.17.1-2.tar.xz 0ae3e9dcd500c92ed8cf9e75997a0be1 *xorg-server-devel-1.17.1-2.tar.xz 16fac69b92a437b9cd797d8bd856a74e *xorg-server-dmx-1.17.1-2.tar.xz ac62929f5789ed8080a55032fa34c03c *xorg-server-extra-1.17.1-2.tar.xz ec69ed455123c737eadd1122968bab29 *xwinclip-1.17.1-2.tar.xz x86_64: ff9942944ce5ccd4a1a994316e59b0f6 *xorg-server-1.17.1-2-src.tar.xz 532de5370f52a0c2c9777efcaef0a08e *xorg-server-1.17.1-2.tar.xz f841880ee0467f89f33ce0d8e4dbf1b4 *xorg-server-common-1.17.1-2.tar.xz 124e514d2d6c49b9672255330f946a0d *xorg-server-debuginfo-1.17.1-2.tar.xz bf27e40d7c78da0d0eeb1074c95377ed *xorg-server-devel-1.17.1-2.tar.xz 705ef8742d93226cbcdbba3d3cf63c88 *xorg-server-dmx-1.17.1-2.tar.xz 5c610c2a3a4cbba6ad79337d8a60fb36 *xorg-server-extra-1.17.1-2.tar.xz 69e2983e1cbca05134f5fd1098833c31 *xwinclip-1.17.1-2.tar.xz -- Jon TURNEY Volunteer Cygwin/X X Server maintainer -- 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/

Help porting the XLaunch feature to autoselect the display number
Hi, i was talking with Jon Turney about this on IRC. I am trying to port this feature of VcXsrv (and XMing also I think) to Cygwin XLaunch: https://sourceforge.net/p/vcxsrv/code/ci/460182676a960385dff96c1563f781213060f6fc/ Attached is my WIP patch. (I know it needs the comments updated for main.cc). There's a bug in main.cc that is causing this to happen when -1 is specified: http://imgur.com/Jv4tpip I am not very familiar with C or C++. I am hoping that someone could give me some advice. (I am much better at Java and bash.)
