[paraview@vbl-sim ~] $ DISPLAY=:0 glxinfo Invalid MIT-MAGIC-COOKIE-1 keyError: unable to open display :0
and the same error for any X program (so I can't run i.e. "xhost +" recommended somewhere). This situation persists through restarts. I trie ro remove the ~/.Xauthority file as recommended elsewhere, but that didn't help either.
(I also tried a second method - starting the launcher through .xinitrc, but it seems slim ignores this file altogether. That's a different problem anyways, as for testing it would be more comfortable if I could launch the server form command line)

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.
