什么是 "dumb" 帧缓冲区？
What is a "dumb" framebuffer?
我用了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.
这个语句中的dumb framebuffer是什么意思？我了解帧缓冲区的含义。里面的dumb字是不是因为没有物理显示输出？
哑帧缓冲区是指没有硬件加速或任何高级功能的帧缓冲区。
