My desktop machine is a Duron 750. My config file includes the
following :
#
# Frame-buffer support
#
CONFIG_FB=y
CONFIG_DUMMY_CONSOLE=y
CONFIG_FB_VESA=y
CONFIG_FB_VGA16=m
CONFIG_VIDEO_SELECT=y
CONFIG_FBCON_ADVANCED=y
CONFIG_FBCON_MFB=y
CONFIG_FBCON_CFB2=y
CONFIG_FBCON_CFB4=y
CONFIG_FBCON_CFB8=y
CONFIG_FBCON_CFB16=y
CONFIG_FBCON_CFB24=y
CONFIG_FBCON_CFB32=y
CONFIG_FBCON_VGA_PLANES=m
CONFIG_FBCON_VGA=m
CONFIG_FONT_8x8=y
CONFIG_FONT_8x16=y
The stock kernel has the following important difference :
# CONFIG_FB_VESA is not set
So if you have a VESA compliant video card that is not one of the
accelerated cards (Matrox, some ATI, some SiS) then you don't have
framebuffer support. For the PIII laptop at work (ATI Rage Mobility
P/M) I had to recomile the kernel and enable VESA framebuffer for it
to work. I did try and give the fb options to the stock kernel but it
didn't work.
