I don't know, it just works for me. Even over VNC, I just tried it from vncviewer on an OpenBSD machine. The "copy from device" is blank until I click the down arrow on it, then it finds /dev/mmcblk0. I'm running it on the machine that's running tightvncserver which I'm logged into. I use VNC a lot, I've maybe gotten a remote X connection to work a couple times years ago. The wrong authentication thing, have you looked at the xhost man page? I remember sometimes you have to do xhost +localhost and any remote machines you want to connect from have to be added in a similar way. With vnc you just need to set up the password with vncpasswd. Then you type like tightvncserver in a terminal window to start it. From the remote machine you type vncviewer and the IP or machine name:display. Server and client software names may be different from mine, you need one of each. I've even had an android vnc client that worked over wifi from a phone. Wheezy or Jessie shouldn't matter, remote X has been around for like 35 years. Since dialup modems have been around.
Why are you at localhost:11? Usually it's localhost:0. Are you logged in from 10 other machines too or something? Try 'echo $DISPLAY' and see what it says, mine says :0. Ooops, the Pi says :1.0, OpenBSD says :0. vnc display numbers are similar but not compatible as far as I know with X connections. I just did (on a pi): pi2# xhost +192.168.7 and got 192.168.7 being added to access control list But when I try xterm -display 192.18.0.7:1 in an ssh window to the pi from openbsd I get crap about running as root and it refuses. There might be a way to put a username in there like you can ssh to user@machine or in mc you cd to ftp://user:pass@machine. 15 years ago my girlfriend at the time thought it was cool so we did it a couple times. VNC I've used a lot more. Daily just about. Sometime it's open for a week at a time.
