I'm trying to open GUI apps (gedit/nautilus/firefox) on a 16.04 machine via SSH from a 14.04 machine. The command I use is:

ssh -X username@ipaddress

and then, for example:

nautilus

However, it doesn't open the app and says 

Segmentation fault (core dumped)

It doesn't say anything else, just that. Can someone help me resolve this?

You need to provide more details. What other error messages do you see? There are a myriad reasons for a segfault. – edwinksl Jul 6 '16 at 6:55
    
Edit your question and provide every command related to your issue. – Thiago Rider Augusto Jul 6 '16 at 17:12
    
@edwinskl, there are no more error messages. Just the segfault. If you can tell me how to get a more verbose message, I can try that. – hack777 Jul 7 '16 at 7:17

I had the same problem. I ran strace with meld and gedit and it indicated that for some reason there was problem finding libGLX_indirect.so.0 library. I attempted a fix by placing relevant symbolic link inside /usr/lib/x86_64-linux-gnu folder:

sudo ln -s /usr/lib/nvidia-361/libGLX_indirect.so.0

and it works now. Would like to know what is the preferred way of fixing it.

I had the same problem and it was hard to find on google, thanks for the solution :-) – sveri Jul 16 '16 at 9:39
    
I had the same problem with i3wm. After an upgrade (probably nvidia drivers), gnome-terminal would no longer start. Dmesg showed a segfault error 4 in libc-2.23.so. Adding the symlink for libGX_indirect resolved the issue. Thanks! – Gareth Western Oct 6 '16 at 20:05

This solved a ton of issues I had with x2go and generally x-forwarding that I thought were policykit related on an Ubuntu 16.04 machine. In some way, the policykit triggered auth dialog depended on this and then silently failed. It seems like quite a few programs had this dependency, e.g. firefox segfaulted as well without the symlink. Thanks a lot! – jmrk84 Jan 11 '17 at 23:33

Great this worked. Thanks. PS: For my machine I had to do: sudo ln -s /usr/lib/nvidia-375/libGLX_indirect.so.0 due to different graphics driver versions. – vikrantt Mar 24 '17 at 22:28

The accepted answer works, however according to Launchpad Bugs, the real cause is libepoxy. libepoxy has been fixed since early 2017, but as of June 2017, it is not available as an updated package for 16.04. I followed the instructions by Raj Bhattacharjea to fix this issue. Specifically:

  1. Downloaded the Zesty (17.04) libepoxy for my architecture from https://packages.ubuntu.com/zesty/libs/libepoxy0 (for me it was amd64).
  2. sudo dpkg -i libepoxy0_1.3.1-1ubuntu1_amd64.deb (or your architecture version)

Problem solved. As much as I don't like using a package from another version, this seems like the cleaner solution, especially since I don't have to worry about my link breaking if I change NVidia versions.
