I have the same problem. If I force indirect rendering like below, it works, but it's not a good solution.
1. Create /etc/lightdm/lightdm.conf.d/50-xserver-command.conf : [SeatDefaults] # Dump core xserver-command=X -core +iglx 2. Restart LightDM # systemctl restart lightdm -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1611745 Title: OpenGL not working through ssh -X Status in xorg package in Ubuntu: Confirmed Bug description: I need to run several OpenGL-depending programs through ssh -x, like tecplot, mayavi or paraview. I connect to the remote machine with ssh -X (or ssh -Y, doesn't matter). Then I test opengl using e.g. glxinfo. The output of glxinfo on the remote machine says that it was unable to create the OpenGL context. In the other remote programs I receive the same error message. On the local machine, it works fine. See the logfiles attached (local_glxinfo.log, remote_glxinfo.log). I configured my Xorg according to the attached xorg.conf. The configuration was produced with nvidia-settings and two manual tweaks, lines 54 and 74. I added those lines because I could not (and still can't) enforce indirect rendering of my graphics card. Indirect rendering is still switched off, see lines 102 and 167 in Xorg.0.log. The issue does also occur when no manually generated xorg.conf is present. I'm using the latest drivers from the package nvidia-361. The issue occurs with and without my graphics card (Intel HD 4600, or GeForce 605). Before I switched to ubuntu-gnome 16.04 I had a xubuntu 14.04 LTS running. There some applications would work, other would not. Now nothing works at all.
