how to activate X with famebuffer

Hello otto,

The question I am asking may the simplest of this field, but I found it no where.
Pls help.

How to activate X with framebuffer.

I am working with the following configuration:-
* Red Hat Linux 7.3 
* Kernel 2.4.18-3 
* Nvidia Riva TNT card 
* Rivafb driver 
* XFree86 4.2.0 
 
My edited the XF86Confoig file as follows( related sections only):-

Section "device"
	Identifier "linix fb"
	Driver "rivafb"	# Is rivafb the right keyword for rivafb.o module?
	BoardName "Unknown"
EndSection

Section "Screen"
	Identifier "Screen0"
	Device "linux fb"
	Monitor "COMPAQ S510"
	DefaultDepth 8
	Subsection "Display"
		Depth 8
	EndSubSection 
EndSection

Is rivafb the right keyword for rivafb.o module?
Is it the driver name(module name) that we should keep in the Driver part of Device section?

If I startx afterb modprobing the rivafb, it results in errors.
# startx 

(EE) Fialed to load module "rivafb" ( module does not exist, 0)
(EE) No devices detected.

Please help me in this regard. I have spend good enough time on this and its I high time get it done.

Is it so easy a question? Just becos I didn't find any info about in the internet and no body replies for question.

Aim Behind all this : 
To debug the rivafb driver when it being called or used by X server( XF86 ).

Regards,
Mukund jampala

How to activate X with framebuffer.

I am not much of an expert, but I see noone is answering...
First of all, you must be sure that the framebuffer level is
working. What does  /proc/fb contain? There should be one or more
line. For example, mine has

0 ATI Radeon Yd

which means that I have one framebuffer unit available. 

Then, have a look at man fbdev. Specifically, the Driver line in your
device section should be 
 
Driver "fbdev"
 
There should be another way. Set 

Driver "nv"

(for nvidia cards, including riva ones) and set 

Option "UseFBDev" "on"

I have no clear idea about what the difference is. Anyway, Have a look
at man nv and man fbdevhw. 

ALL THIS IS PURELY THEORETICAL from my point of view!! You need to
experiment a bit.
