Problems Ssh’ng into my Beaglebone Black using my W530 with Nvidia drivers

I was moving along, having all kinds of fun ssh’ng into my Beaglebone using my W530 laptop with out any difficulties.  My problems started when I wanted do use dual monitors with my docking port.   In order to do that, I needed to install the Nvidia proprietary drivers.   I got that working and than  wound up having all kinds of problems running axis in machinekit.

Here’s what was happening:

ssh -X machinekit@
Debian GNU/Linux 8

Machinekit Debian Image 2017-02-12


default username:password is [machinekit:machinekit]

machinekit@’s password:

So this took me a while to figure out which a little help from from Linux guru’s from the makerspace I belong to.

I found some suggestions at
This solution talked about  adding this to an xorg,config file in the /etc/X11/ folder

Section “ServerFlags”
Option “AllowIndirectGLX” “on” # or “off”

I tried that and I couldn’t get that to work.
I found another fix here:

Recently, Xorg changed its behavior to disallow indirect GLX by default. This means that ssh -X no longer works with OpenGL applications, which is a pretty serious problem.

The only way to re-enable indirect GLX is to pass +iglx to Xorg. However, GDM has no way to pass arbitrary flags to Xorg.

The only workaround is to rename Xorg to Xorg.original and replace it with a wrapper that adds +iglx, e.g.:

exec /usr/bin/Xorg.original "$@" +iglx

(for you kids at home, don't forget to sudo chmod +x /usr/sbin/Xorg)

So first things first we need to locate Xorg

jonasthomas@jonasthomas-ThinkPad-W530:~$ which Xorg

sudo cp /usr/bin/Xorg /usr/bin/Xorg.original

So with the with Xorg program copied into Xorg.original just replace the contents of Xorg with the file above.

This worked for me. If you have this issue as well, I hope it helps you out as well.
