Xauthority is missing the display number
Multi tool use
2
When I run on my local machine (Ubuntu 18.10) xauth list the output is not showing the display number:
$ xauth list
c7h/unix: MIT-MAGIC-COOKIE-1 37bb744d95232b4e29aea1320b0a0e2d
#ffff#633768#: MIT-MAGIC-COOKIE-1 37bb744d95232b4e29aea1320b0a0e2d
My env $DISPLAY variable contains the value :1:
$ echo $DISPLAY
:1
So I was expecting to see 1 after c7h/unix::
c7h/unix:1 MIT-MAGIC-COOKIE-1 37bb744d95232b4e29aea1320b0a0e2d
The value is also missing if I manually parse the file inside the env variable $XAUTHORITY with Python:
if filename is None:
filename = os.environ.get('XAUTHORITY')
if filename is None:
try:
filename = os.path.join(os.environ['HOME'], '.Xauthority')
except KeyError:
raise XConnectionError("$HOME not set, can't find ~/.Xauthority")
try:
xaf = open(filename, 'rb')
raw = xaf.read()
xaf.close()
except IOError as err:
raise XConnectionError("Can't read ~/.Xauthority: %s" % err[1])
return
n = 0
entries =
try:
while n < len(raw):
family, = struct.unpack('>H', raw[n:n + 2])
n = n + 2
length, = struct.unpack('>H', raw[n:n + 2])
n = n + length + 2
addr = raw[n - length: n]
length, = struct.unpack('>H', raw[n:n + 2])
n = n + length + 2
num = raw[n - length: n]
length, = struct.unpack('>H', raw[n:n + 2])
n = n + length + 2
name = raw[n - length: n]
length, = struct.unpack('>H', raw[n:n + 2])
n = n + length + 2
data = raw[n - length: n]
if len(data) != length:
break
entries.append((family, addr.decode('utf-8'), num.decode('utf-8'), name.decode('utf-8'), data))
How can I figure out which of the auth is the one associated with the value reported by $DISPLAY?

Your second cookie also looks not quite right. What happens when youxauth extract some_file :1and thenxauth -f some_file list? If you get the first line again, I don't understand what's happening. If you get a different line, my guess would be "auth file corrupt; remove it, log out, log in, see if it gets better".

Unfortunately the result is exactly the same as the$XAUTHORITYone.
