One more step closer to the goal it seems - if run:
export XAUTHORITY=/var/run/slim/slim.auth DISPLAY=:0 xhost +as root, I can get the launcher to start, and not die with an X-related error (cumbersome workaround, but I guess I can find a better way later).
[paraview@vbl-sim ~] $ cat /etc/httpd/paraview-mapping/proxy.txt be12802a-137f-11e6-b12c-002590e6af35 vbl-sim.eli-beams.eu:9003 [paraview@vbl-sim ~] $ ps aux | grep pvpythonparaview 1792 1.2 0.1 1393740 144956 pts/1 S+ 13:42 0:02 /usr/local/lib/paraview-5.0/pvpython /usr/local/lib/paraview-5.0/site-packages/vtk/web/launcher.py /etc/httpd/paraview-launcher.config -d paraview 1887 1.6 0.1 1519164 237520 pts/1 Sl+ 13:43 0:02 /usr/local/lib/paraview-5.0/pvpython -dr /usr/local/lib/paraview-5.0/site-packages/paraview/web/pv_web_visualizer.py --port 9003 --data-dir /var/paraview/data -f --authKey 3ZXwyWwTz7aPjT9p
Now when I try to open an app from the browser, it still doesn't work (waits forever to load some part, etc.), and I see thist in the paraview log:

and a lot of lines which contain just the repeating plus signs. On 05/05/16 16:23, Sebastien Jourdain wrote:
You were on the right track with DISPLAY=:0 but I'm wondering if you setup a "virtual" monitor or if your "paraview" user is auto logged in a X session or if it stuck at the "login" panel?You can find some information about the virtual screen here: (Search for "Screen") http://kitware.github.io/paraviewweb/docs/guides/graphics_on_ec2_g2.html And for the autologin if it is needed. (Note on EC2 the user start X hence no need to login...) https://github.com/Kitware/paraviewweb/blob/master/tools/ansible/roles/paraview/tasks/Ubuntu.yml SebOn Thu, May 5, 2016 at 6:58 AM, Jiří Vyskočil <[email protected] <mailto:[email protected]>> wrote:Hello, 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. 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. 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: $ ./launch-paraview.sh 2016-05-05 14:54:17,528:INFO:twisted:Site starting on 9000 2016-05-05 14:54:17,528:INFO:twisted:Starting factory <twisted.web.server.Site instance at 0x7fe20da6a998> 2016-05-05 14:55:09,655:INFO:twisted:"127.0.0.1" - - [05/May/2016:12:55:09 +0000] "POST /paraview/ HTTP/1.1" 503 78 "https://vbl-sim.eli-beams.eu/apps/Visualizer/"; "Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0" $ cat 965318f2-12c0-11e6-a3cb-002590e6af35.txt 2016-05-05 14:55:06+0200 [-] Log opened.
