Why didn't vesafb information be output? Is it interrupted in that step? Gradually tracking:

Because of the limited support of graphics card manufacturers, driving the graphics card under Linux has always been a problem. To solve this problem, the Linux 2.2.x version offers a new solution---Use the frame buffer device, through the VESA VBE 2.0 standard, using the graphics SVGA features, with XFree86 Xf86_fbdev, drive your graphics card. This can do you a favor ...

After the installation is complete, you still cannot access the graphic interface using start x in my environment. Because of the fixed graphics card, it is the INTEL82830M graphics card and you have tried to modify XORG. the CONF file cannot be changed to I810 or INTEL. You have to use VESA to smoothly enter
