Are you by chance doing this on a MacOS system? If so I believe MacOS does not support the X11 SECURITY extension at all, so your only option is to use trusted forwarding (the -Y flag).

Not sure what the current state is. > number of extensions: 21 > Apple-DRI (opcode: 128, base event: 64, base error: 128) > Apple-WM (opcode: 129, base event: 68, base error: 130) > BIG-REQUESTS (opcode: 134) > DAMAGE (opcode: 142, base event: 97, base error: 154) > DOUBLE-BUFFER (opcode: 144, base error: 155) > GLX (opcode: 148, base event: 101, base error: 159) > Generic Event Extension (opcode: 130) > MIT-SCREEN-SAVER (opcode: 143, base event: 98) > MIT-SHM (opcode: 132, base event: 72, base error: 132) > Present (opcode: 145) > RANDR (opcode: 141, base event: 95, base error: 149) > RENDER (opcode: 140, base error: 144) > SHAPE (opcode: 131, base event: 71) > SYNC (opcode: 135, base event: 90, base error: 138) > X-Resource (opcode: 146) > XC-MISC (opcode: 137) > XFIXES (opcode: 139, base event: 93, base error: 142) > XINERAMA (opcode: 138) > XInputExtension (opcode: 133, base event: 73, base error: 133) > XKEYBOARD (opcode: 136, base event: 92, base error: 141) > XVideo (opcode: 147, base event: 99, base error: 156) This is where it would be. You'd be looking for a line similar to the following (from my FreeBSD 11.3 desktop): SECURITY (opcode: 137, base event: 86, base error: 138) -- Greg Veldman freebsd@gregv.net
