However, now having upgraded to Python 3.6.13 I noticed that Xlib is now unable to connect to X11. The same error appears for Python 3.8 and 3.9. After overwriting _socket.cpython-36m-x86_64-cygwin.dll with the one from 3.6.9 Xlib is working again, so my guess is that this is due to some change in the socket module.\r\n\r\nI debugged the issue a bit and found this to be working in Python 3.6.9\r\n```\r\nPython 3.6.9 (default, Jul 21 2019, 14:33:59)\r\n[GCC 7.4.0] on cygwin\r\nType \"help\", \"copyright\", \"credits\" or \"license\" for more information.\r\n\u003e\u003e\u003e display = \":7\"\r\n\u003e\u003e\u003e data = b'l\\x00\\x0b\\x00\\x00\\x00\\x12\\x00\\x10\\x00\\x00\\x00MIT-MAGIC-COOKIE-1\\x00\\x00\\xc5\\xc1C\\xc1Y}\\xe6\\x1e\\x88P\\xab\\x98\\xd0\\x91\u003c%'\r\n\u003e\u003e\u003e import select\r\n\u003e\u003e\u003e from Xlib.support import lock, connect\r\n\u003e\u003e\u003e name, protocol, host, displayno, screenno = connect.get_display(display)\r\n\u003e\u003e\u003e socket = connect.get_socket(name, protocol, host, displayno)\r\n\u003e\u003e\u003e i = socket.send(data)\r\n\u003e\u003e\u003e select.select([socket], [], [], None)\r\n([\u003csocket.socket fd=3, family=AddressFamily.AF_UNIX, type=SocketKind.SOCK_STREAM, proto=0, raddr=/tmp/.X11-unix/X7\u003e], [], [])\r\n\u003e\u003e\u003e socket.recv(512)\r\nb'\\x01\\x00\\x0b\\x00\\x00\\x00:\\x07\\xd0\\xab\\xb5\\x00\\x00\\x00`\\x00\\xff\\xff\\x1f\\x00\\x00\\x01\\x00\\x00\\x18\\x00\\xff\\xff\\x01\\x06\\x00\\x00  \\x08\\xff\\x00\\x00\\x00\\x00The Cygwin Ports project\r\n```\r\nwhile in Python 3.6.13 the same commands yield a Connection reset\r\n```\r\nPython 3.6.13 (default, Feb 16 2021, 07:46:47)\r\n[GCC 10.2.0] on cygwin\r\nType \"help\", \"copyright\", \"credits\" or \"license\" for more information.\r\n...\r\n\u003e\u003e\u003e socket.recv(512)\r\nTraceback (most recent call last):\r\n  File \"\u003cstdin\u003e\", line 1, in \u003cmodule\u003e\r\nConnectionResetError: [Errno 104] Connection reset by peer\r\n```\r\n\r\nAny help would be much appreciated!","author":{"url":"https://github.com/robertschulze","@type":"Person","name":"robertschulze"},"datePublished":"2023-07-27T09:04:32.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/267/python-xlib/issues/267"}
