Hi, Leah-

What is the output of:

which Xvfb

?

Also, could we please see the output of:

afni_system_check.py -check_all

?

That last command will tell us what operating system that you are using, which I am not of at present (presumably some form of Linux). I assume that you gave your IT folks the pointer to the AFNI setup instructions at some point?
