Getting 800x600 to stretch and fill screen

[echo6]

I've got a Sony Vaio PCG-FX101, how can I get the 800x600 to fill the screen? Also in X whenever I switch to 800x600 ctrl alt - the screen shrinks to occupy the middle. Worse still is the fact that the bottom third of the screen is not reachable with the mouse!

I'm in the process of recompiling the kernel to support framebuffer in the hope that I can also get 1024x768 at the console and not just for X.

OK I've recompiled the kernel following the guide from https://forums.gentoo.org/viewtopic.php?t=49036 As soon as I boot I'm prompted with an undefined mode error. Also running fbset shows that I have no /dev/fb0. From what I understand of the kernel Documentation I may not have a Vesa 2 compliant graphics card. I find that hard to believe, I've even tried using the i810fb in the grub.conf, it's also compiled into the kernel.

Any ideas what I can do to get things working?

Can't help with frame buffer, except to say you are on the right lines to make the console fill the entire screen.

If you must have 800x600 expanded to fill the screen (it'll look rubbish, but you may nevertheless prefer it to a black border), I've heard it said that you should look in the BIOS settings for something relevant. I can't really help further though, as I am not a laptop user.

Thanks for the response, unfortunately there are no BIOS settings

The Vaio has Windows utils to enable 800x600 stretch via a Fn key stroke, and belive me I've also looked at the sonypi module and the sonykeyd, but there is nothing available to do it. I've also got a Dell notebook and the keys work for that but then Toshiba and Dell notebook stuff is available in the kernel.

I've checked the Linux on lap top web site and there is some config stuff for framebuffer etc mentioned there for this model, but I'm still gettting no joy with it I've compiled the following framebuffer drivers into the kernel:
VGA text console
VESA VGA graphics console
Virtual Frame Buffer Support
Advanced low level driver options
Monochrome support
2 bpp packed pixles support
4 bpp
8 bpp
24 bpp
32 bpp
VGA 16-color planar support
VGA characters/attributes support
HGA monochrome support
under Character devices I have
/dev/agpgart
DRI
Intel i810

I've also got a Dell notebook. The Live 1.4 CD boots and fills the entire screen no problem, on the Vaio it doesn't and asks for input for screen size.

I tried the XF86Config from the FX101 Linux on laptops web site http://cwrose.de/vaio/fx101.html and got an error in respect of /dev/fb0, /dev/fb exists so I created a softlink. According to him he managed to get a 1024x768 console I am now going to attempt to configure /etc/fb.modes and consulting http://www.tldp.net/HOWTO/Framebuffer-HOWTO.html but I feel I'm stabbing in the dark here

Appologies for posting a reply to my own message!

This is for any one else who may have the same Vaio or an i810 grafix adapter. So far I've only managed to get the kernel to compile using the vanilla sources, 2.4.20. I went to www.bootsplash.org and applied the kernel patch. I found the i810 framebuffer device driver here http://i810fb.sourceforge.net and applied the i810 lite kernel patch. I also followed the advice found here https://forums.gentoo.org/viewtopic.php?t=49036. Everything worked!!!
