Smile Framebuffer driver


Hi,

Have a look at the following link " http://i810fb.sourceforge.net/ ". This link will allows us to download drivers for frame buffer for intel 810 chipset. How to install the Framebuffer driver ? How to make the kernel to know that a new driver has been installed ? Is it necessary to recompile kernel after a installing a new driver ? I studied the Installation Guide "Intel 810/815 Framebuffer HOWTO " in the above web page. There it has been specified to recompile the kernel. Is it necessary ? What i need is to install the intel 810 Framebuffer driver and make it known to kernel and enable Framebuffer(/dev/fb0) while booting. How can we do this ?

i'm not sure quite what that driver is for, AFAIK all grpahics cards bult since... 1995 or probably even earlier will be vesa 2.0 compliant, meaning that they can use the vesafb framebuffer driver. There is seldom any need to use a more specific FB driver, unless you are after dual head systems or other complex fb setups. it's notmaly just a case of botting into fb mode. add vga=788 or vga=791 to your lilo or grub config file in the relevant place and you *should* make it load the framebuffer automatically.

Unhappy Framebuffer Driver

Hi,
I added the following 2 lines in lilo.conf.

append="video=vesa:ywrap,mtrr"
vga=788
and executed /sbin/lilo in shell prompt and then rebooted ths system.

While booting the following is displayed.

Loading Linux
You passed an undefined mode number
Press <RETURN> to see video modes available, <space> to continue or wait 30 secs.
Video adapter: VESA VGA
Mode: COLSxROWS
0 0f00 80x25
1 0f01 80x50
2 0f02 80x43
3 0f03 80x28
4 0f04 80x30
5 0f05 80x34
6 0f06 80x60

Enter mode number or 'scan' :

I entered 0 .

Here it is still in text mode. But actually what we want is graphics mode to enable frame buffer. How to enable the frame buffer with default driver as you said ?

yeah, the modes listed there are only text based, not framebuffer. fb modes are those numbers plus 300 i *think*... 788 is 800x600 and 791 is 1024x768 (they are decimal not hex... that'd be 0x3something).

maybe you're card does require a special fb driver.... i wouldn't know about that at all if it does. if it will run under vesa, which it really really should then you should need that append line by default, just vga=788. it does say that it was an invalid mode though.... there are a number of fb mode tables you can find from google which will give all the hex values which you should be able to type directly into the lilo mode selection prompt you got there (which is conventionally found with vga=ask)

Thumbs up Framebuffer driver for intel 810 chipset

Hi,
Let me forward my doubt more precisely. I am working Mercury motherboard with Intel 810 chipset with onboard Graphics controller.

Is vesa framebuffer driver is supported by Intel 810 chipset ?
The answer is no. I came to know this from a faq in Intel web site.

What is the graphics card name which is present onboard in Intel 810 chipset ?

What framebuffer driver should be used for Intel 810 chipset with onboard graphics controller ?

And how to invoke the same ?

Help me to solve the above questions.
