I used Xvfb recently for running my tests using Jenkins on an Ubuntu instance. On researching up on Xvfb, I understood what the X and virtual part meant in Xvfb. I got stuck at the meaning of "dumb framebuffer". According to X.org:
It emulates a dumb framebuffer using virtual memory.
What does dumb framebuffer mean in this statement? I understand what framebuffer means. Is the dumb word in there because there is no physical display output?
