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 Seb On Thu, May 5, 2016 at 6:58 AM, Jiří Vyskočil <[email protected]> wrote: > Hello, > > > I'm trying to set up a Paraview Web server on a Fedora 23 machine.
