<br>
<br>
I'm trying to set up a Paraview Web server on a Fedora 23
machine. The serves is not connected to a monitor or a
keyboard (I only have access through ssh), but it has a
nvidia GPU which I want to use for paraview.<br>
<br>
<br>
I have installed xdm to run the X server, and verified that
it is in fact running with the correct nvidia drivers (by
checking the Xorg.0.log file). The problem is I don't know
how to run the paraview webserver on the X display when
there's no one physically logged in - I can only get to the
server via ssh. When I log in, and switch to the paraview
user, the DISPLAY and XAUTHORITY variables are empty.<br>
<br>
<br>
The webserver itself is running (apache + the python
launcher), but when I try to open any of the example
applications, I get an error like this:<br>
<br>
<br>
$ ./launch-paraview.sh<br>
