Hi, I have deployed nuxeo 9.1 on Red Hat Enterprise Linux Server release 7.3 & in that I have installed libreoffice-4.1.2. When I am trying to open viewer for doc/excel file, I am getting following error:

[/usr/lib64/libreoffice/program/soffice.bin X11 error: Can't open display: , Set DISPLAY environment variable, use -display option, or check permissions of your X-Server, (See “man X” resp. “man xhost” for details)]

Can any one solve this issue!!
