Framebuffer，等于是 软显卡 的意思吗？

忽然看到这么一个概念。

“Framebuffer”: this is the replacement for VESA that doesn’t rely on old BIOS/DOS features. In this case, the computer firmware (EFI) configures the display for us, and tell us “this is the memory address where the graphics is, just write your pixels there”. We can change the resolution, but only from the bootloader, not after the OS is started. So, in that case, you get one single resolution in Screen preferences, but you can select one from the boot menu.
