Console Framebuffer Issues / GeForce4 - Red Hat stock kernel 2.4.20-13.9

Console Framebuffer Issues / GeForce4 - Red Hat stock kernel 2.4.20-13.9

[Robert Keith Vaughan]

Hello:

I apologize if this is the wrong list to post to, but it was suggested in a 
post I dug up through a google search.  I normally like to figure things out 
for myself, but this one is really starting to tick me off.

I am using Red Hat 9.0 with the stock 2.4.20-13.9 kernel.  I am attempting to 
get framebuffer support working on the console with little success. The 
relevant PC specs are as follows:

Athlon XP 2000+
1 GB RAM
Geforce4 ti4400

From what I have been able to ascertain, vesafb is compiled into this kernel 
instead of loading as a module.  I looked at the information for the rivafb 
driver and it doesn't appear to support the GeForce4 cards.  What info I have 
been able to dig up suggests that you can get non-accelerated framebuffer 
support for the GeForce4 using vesafb.  I cannot, however, get it to work.

I have tried to pass the following kernel arguments via grub.  All I get is a 
blank screen"

video=vesafb,xres:1024,yres:768,bpp:16 vga=791

	AND (just in case I COULD get the rivafb module to support it)

video=rivafb,xres:1024,yres:768,bpp:16 vga=791 

I have played around with the bpp and vga= settings (trying 8, 16 and 24 
respectively) .  No luck.  Get a blank console up until kdm loads. And I 
don't see anthing in the dmesg logs either.  Sigh.

When I issue fbset I get the following error:

  open /dev/fb0: No such device

Which leads me to believe that the stock kernel isn't seeing a framebuffer 
device despite the fact that vesafb is compiled in.  

I have not yet tried to compile a custom kernel precisely because of 1.) 
vesafb is complied into this kernel, AND 2.) Nothing I have read seems to 
indicate that compiling rivafb into the kernel will help with my issue ( and 
I have not been able to get rivafb to load as a module in any event...)

So, I am stumped.  I'm sure its something stupid on my part....but could 
anyone tell me A.) what I am doing wrong here, and/or B.) if anyone has 
gotten console framebuffer support running on a stock Red Hat kernel...

Thanks for putting up with the long winded (and I sure stupid) questions..

Keith Vaughan

  try passing "mem=512M" to kernel in lilo. It worked for me...I also 
have 1GB of ram
