I had installed Cygwin with X server on a Windows 10 machine without problems.
Now I have converted the same machine to Windows 11 but not I am not able to
run X server anymore. I get no meaningful errors. I have tried also
reinstalling Cygwin with the same result. Here is the output when running the
simplest case:

winDetectSupportedEngines - RemoteSession: yes
Huh, this indicates that you're using RDP (or similar). Is that the
case? If so, do things work correctly in a local session?
winDetectSupportedEngines - DirectDraw4 installed, allowing ShadowDDNL
winDetectSupportedEngines - Returning, supported engines 00000005
Is the XWin process hung at the point? or has it crashed?
Since it seems like the problem is occurring while initializing DD4,
perhaps adding the command line argument '-engine 1' might work around it?
