D	fbcon.rst	5 The framebuffer console (fbcon), as its name implies, is a text 6 console running on top of the framebuffer device. It has the functionality of 8 features that can be attributed to the graphical nature of the framebuffer. 10 In the x86 architecture, the framebuffer console is optional, and 14 What are the features of fbcon? The framebuffer console supports 22 The framebuffer console can be enabled by using your favorite kernel 28 In order for fbcon to activate, at least one framebuffer driver is 42 GOTCHA: A common bug report is enabling the framebuffer without enabling the 43 framebuffer console.
