Designer throws above exception on Linux machine during startup.

Red Hat Enterprise Linux Server release 7.x

Please follow below steps :
------------------------
Step 1: 

- Configure X Server Manager (X11) or XVFB (X Virtual FrameBuffer).We have provided a simple guideline for installing and configuring XVFB on HP-UX, Linux, and Solaris.If x11 not configured please follow the attached PDF document.

Step 2: 

- Create a file named 'local.conf' with the below XML tag:

***************************************************
<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
<alias>
<family>serif</family>
<prefer><family>Utopia</family></prefer>
</alias>
<alias>
<family>sans-serif</family>
<prefer><family>Utopia</family></prefer>
</alias>
<alias>
<family>monospace</family>
<prefer><family>Utopia</family></prefer>
</alias>
<alias>
<family>dialog</family>
<prefer><family>Utopia</family></prefer>
</alias>
<alias>
<family>dialoginput</family>
<prefer><family>Utopia</family></prefer>
</alias>
</fontconfig>
***************************************************
- Copy "local.conf" to '/etc/fonts/' directory on Linux machine.

Step 3:

- Execute following command to check fonts installed on Linux machine:
******************
rpm -qa|grep -i font
******************

- If following fonts are not present, try to install following fonts on Linux machine.
