Question X11 Remote connection problems


Not sure if this is the proper forum but here goes.
I'm attempting to connect to an embedded Linux box (running Yocto) via ssh X11 forwarding. My desktop machine is a Mac running the XQuartz 2.7.8. Now, I am able to ssh -X into another Mac also running XQuartz and launch xeyes with it. So I'm reasonably convinced that the Mac side of things is working.

I've got the X11 options in sshd_config on the Linux box set up thusly:

AllowAgentForwarding yes
AllowTcpForwarding yes
X11Forwarding yes
X11DisplayOffset 10
X11UseLocalhost no

When I ssh -X root@ts-imx6.local, I get the following:

/usr/bin/xauth: file /home/root/.Xauthority does not exist
/usr/bin/xauth: (stdin):1: bad display name "ts-imx6:10.0" in "remove" command
/usr/bin/xauth: (stdin):2: bad display name "ts-imx6:10.0" in "add" command

When I do something dead simple like xset -q > /dev/null, I get
xset: unable to open display "ts-imx6:10.0"

Some online references talk about the DISPLAY environment variable not being set properly and that it should be localhost:10.0 so I try

export DISPLAY=localhost:10.0

Now, when I try xset -q > /dev/null, I get

X11 connection rejected because of wrong authentication.
xset: unable to open display "localhost:10.0"

At this point, I'm at a loss as to what I'm missing or doing wrong.

I'd try using a non-root user, maybe your embedded system doesn't allow root gui

No soap, Doc. Slightly different but no luck. As soon as I log in to a regular user I get:

/usr/bin/xauth: (stdin):1: bad display name "ts-imx6:10.0" in "remove" command
/usr/bin/xauth: (stdin):2: bad display name "ts-imx6:10.0" in "add" command

Then when I try the simplest X11 command I get:

ts-imx6:~$ xset -q > /dev/null
xset: unable to open display "localhost:10:0"
ts-imx6:~$

I am not sure if it is right, but I got the nearly same fault in the past about to run x11vnc on the system until i could manage to tell the unit who has got the rights to use the display. The question is only how you get that in a ssh -X session becaus I did not use that until today. I might try it as I did always use x11vnc for getting somethin simular. Had to set up lots of things in my .x11vncrc to make it working but since than its working fine for me.
