#83 OpenNx fails to open a session with El Capitan

[Pascal Bonnefond]

I am using OpenNx since a long time and it is a great software.
However, when I upgraded to El Capitan it is not working. Here is the description: when clicking on resume a session, everything goes as usual but at the end "starting the session" it laung Xquartz but the session is not started and the OpenNx GUI comes back to the login. Note that Xquartz is launched (and I have uprgraded it to 2.7.8).
I hope that you can correct this very soon because I am stucked and cannot work remotely on my computer

Hopefully the following details are useful to anyone who is running OSX and OpenNX (some of it is a summary of other posts).

On El Capitan:

• Download and install an El Capitan compatible version of XQuartz (>2.7.7)
• Edit the file, /Applications/OpenNX/OpenNX.app/Contents/MacOS/OpenNXapp so that it looks like this (adding the line to set the DISPLAY variable):

1 2 3

#!/bin/sh export DISPLAY=:0 exec /Library/OpenNX/bin/opennx

Now you should be able to restart OpenNX and connect.
(Disclaimer: This has only been tried this while using version 0.16.0.725 of OpenNX, but other versions may work)

On Yosemite:

• Download and install version 0.16.0.725 of OpenNX
• Download and install version 2.7.5 of XQuartz

Note for both Yosemite, and El Capitan users:

In both cases, after rebooting, you may need to do the following (in order) for OpenNX to run:

1. Start XQuartz
2. Quit XQuartz
3. Start OpenNX

If you accidentally start OpenNX first, make sure to quit the application (and XQuartz) before performing the above steps.

Thanks Fred. This trick worked for me on El Capitan. Unfortunately, I recently had to upgrade to Max Sierra and now I'm back to the same issue, where as mentioned in the original post - "everything goes as usual but at the end "starting the session" it launch Xquartz but the session is not started and the OpenNx GUI comes back to the login"

Have you or anybody have any luck with Sierra? I'm using the same OpenNX and XQuartz version you mentioned above

Hi,
Is it fixed now for sierra because I plan to install it.
Best,
Pascal

Haven't tested on Sierra, but on El Capitan I've had the same issue, not fixed by Fred's suggestion, and got a working OpenNX by compiling it from source.

I followed the instructions at http://www.nerdenmeister.org/2013/11/09/build-opennx-on-os-x-10-9-mavericks/

and for the initial configure step used

/configure --with-wx-config=/opt/local//Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/3.0/bin/wx-config CPPFLAGS=-I/opt/local/include

There's a bug when you initially connect it tries to delete a key file in your home directory which has already been deleted by something else. I've patched this previously for Linux and can hunt out that patch. There's also a lot of WxWidgets warnings but these can be surpressed after the first time they appear.

I'm trying to get 'make dmg' working at the moment which would create a full OpenNX installer dmg.

See if the above works for you though.

OpenNX 0.16.725 and XQuartz 2.7.5 works for me on Sierra.

I had been using this exact combination on El Capitan and it was working fine. I bought a new laptop, copied a backup from Time Machine, updated to Sierra, and OpenNX stopped working. I deleted and reinstalled both OpenNX and XQuartz and it started working.
