When trying to run xterm: No Xauth Cookie found :(

[KernelDeimos]

Hello, thanks for the help on issue #149, I've been following through the documentation and at this point I've gotten to an error that I'm having trouble getting past. I'm running compositor-shell and compositor-proxy-cli on the same host, and trying to run xterm. I see the following error: No Xauth Cookie found :(.

I'm not sure where the Xauth cookie comes from so it's difficult for me to find the source of the problem. I did try creating an "empty" auth cookie based on a default value I saw in auth.ts:

diff --git a/libs/xtsb/src/auth.ts b/libs/xtsb/src/auth.ts
index efedda8..7c17e2c 100644
--- a/libs/xtsb/src/auth.ts
+++ b/libs/xtsb/src/auth.ts

   socketFamily: 'IPv4' | 'IPv6' | undefined,
   cookie?: { authName: string; authData: string },
 ): Promise<void> {
-  if (!cookie || paddedString(cookie.authData).length === 0 || paddedString(cookie.authName).length === 0) {
-    throw new Error('No Xauth Cookie found :(')
+  // if (!cookie || paddedString(cookie.authData).length === 0 || paddedString(cookie.authName).length === 0) {
+  //   throw new Error('No Xauth Cookie found :(')
+  // }
+  if (!cookie) {
+    cookie = {
+      authName: '',
+      authData: '',
+    }
   }
 
   const byteOrder = getByteOrder()

After trying this I quickly realized this approach wouldn't get me very far, because I got an error on the next piece of code that seems to expect this cookie not to have empty string values:

RangeError: Invalid format string: <BxHHHHxx0s0s

I'm not sure what else I can try next so any help is appreciated. If I can get just enough information to figure the rest out on my own, I'll return the favor by adding any applicable documentation.

I believe you need to add it using these xauth commands (I’ll update the docs with more details).
