How to enable framebuffer


How do I enable framebuffer? I'm using Fedora 7 Linux with a nVidia 8600GT graphics card.

I don't know if it's installed (I would assume it's not, there's no /dev/fb0).

How do I install it?

search your /boot/config

I have editted it just to show my examples....to show if your kernel supports it either y for inbuilt or m for module

# Graphics support
CONFIG_FB=y
plus some others in same section and
# Frame buffer hardware drivers
CONFIG_FB_VESA=y

pls report if these show as y or m.

2) BTW do you run the nvidia propiertry driver?

1) It says CONFIG_FB=y and and CONFIG_FB_VESA=y

2) I'm using the Livna nvidia driver (not the one off of the nvidia.com website)

What do I do now?

well here is where we part company...I use nvidia and accelerate my video card...as cheap as it is using the nvidia tainted kernel with a different /etc/X11/xorg.conf

I had to have a google to see there was a Livna site. So I am not the best to tweak that driver and might be prone to be biased and try and get you to a nvidia.

2) so post your xorg.conf or maybe Fedora still uses XF86Free.conf please

3) also, I understand you do not know if its installed in your first post...but we have established that its available in your current kernel.

so what displays are breaking for you?

what games can you not run without it?

Xorg.conf file:
Code:
# Xorg configuration created by system-config-display

Section "ServerLayout"
	Identifier     "single head configuration"
	Screen      0  "Screen0" 0 0
	InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

Section "Files"
	ModulePath   "/usr/lib/xorg/modules/extensions/nvidia"
	ModulePath   "/usr/lib/xorg/modules"
EndSection

Section "ServerFlags"
	Option	    "AIGLX" "on"
EndSection

Section "InputDevice"
	Identifier  "Keyboard0"
	Driver      "kbd"
	Option	    "XkbModel" "pc105"
	Option	    "XkbLayout" "us"
EndSection

Section "Monitor"
	Identifier   "Monitor0"
	ModelName    "NEC MultiSync LCD1530V"
	HorizSync    31.0 - 60.0
	VertRefresh  56.0 - 75.0
	Option	    "dpms"
EndSection

Section "Device"
	Identifier  "Videocard0"
	Driver      "nvidia"
	Option	    "AddARGBGLXVisuals" "True"
EndSection

Section "Screen"
	Identifier "Screen0"
	Device     "Videocard0"
	Monitor    "Monitor0"
	DefaultDepth     24
	SubSection "Display"
		Viewport   0 0
		Depth     24
	EndSubSection
EndSection

Section "Extensions"
	Option	    "Composite" "Enable"
EndSection
As for what programs don't run, I can't change the text size and resolution stuff in the command line only mode (with no X), I heard this was because framebuffer was not enabled. The size of text when running without X is very large, so some of the text runs off the screen.
