Cygwin/X XDMCP Issue
Hi, Im having some issues when running Cygwin/X in combination with XDMCP. Opening a cygwin prompt and running 'startx' works as expected. When I try to connect to my remote Linux system with the command 'xwin -query 192.168.178.22' (or with the 'XLaunch' program and choose XDMCP) the screen stays black. I get the impression that I do get an connection, but that there is a display problem. When I try to close the blacked out Window, I get the message 'Exiting will close all screens on this display. There are currently 6 clients connected. Proceed with the shutdown of this display/server ?' When i specify 'xwin -retro -query 192.168.178.22', the cursor appears and the screen gets gray-ish, but mouse clicking has no effect. Setting 'xwin -engine 16 -query 192.168.178.22' results in a blue background and an error: 'Failed asserion key - size == 0 at line 147 of file /qip/cygport-git/x-org-server/x-org-server-1.16.3-1.x86_64/src/xserver-cygwin-1.16.3-1/include/privates.h in function dixSetPrivate' and a core dump. Any and all ideas are more than welcome, as I have no idea whats going on here.
