Hi,
Are you remotely accessing the machine you are running CAVE on or physically 
sitting on the machine looking at the screen? Where are you seeing those errors 
- in the terminal? Are you running CAVE as the user awips (as it was created 
from the awips_install.sh script)? What is your output when running a "rpm -qa 
| grep xcb"? 

These are the xcb rpms versions that I have installed and currently working (on 
centos7):
libxcb-devel-1.13-1.el7.x86_64
xcb-util-image-0.4.0-2.el7.x86_64
xcb-util-0.4.0-2.el7.x86_64
xcb-util-renderutil-0.3.9-3.el7.x86_64
xcb-util-keysyms-0.4.0-1.el7.x86_64
xcb-util-wm-0.4.1-5.el7.x86_64
libxcb-1.13-1.el7.x86_64
