i810 frame buffer not working.

TomE · 2006-04-12 22:04:05

has anyone got a framebuffer for i810 working?
I cannot get the frame buffer working with the archck or arch kernel.
I've tried video=i810fb video=intelfb video=vesafb and video=vesafb-tng, using both vga=773 and video=blah:1024x768-16@75

the intelfb module only fully works on certain intel cards. i have vesafb-tng working on my i855gm system. I boot with video=vesafb:ywrap,mtrr,800x600-32@70 i had a link to the list of cards the intelfb module supports but i can't seem to find it right now.

Sorry I did not post back earlier I'd forgotten I'd posted here.

That does not work nothing happens and threes not even a /dev/fb0
I've done some googleing and it looks like the i810 needs a custom kernel

It's an old dell optiplex I got it from work and have done it up for some one
else without computer there not going to be using it without x.org so it
does not really matter, they'll have to live with out gensplash.

i got intelfb to work. just compile intelfb and vesafb support into the kernel then change your kernel line to something like this:

kernel /bzImage root=/dev/hda6 resume2=swap:/dev/hda5 video=intelfb:ywrap,mtrr,800x600-24@70 vga=789 splash=silent,fadein,theme:darch console=tty1 quiet ro

note: that should all be on 1 line but line wrapping messes with it.

I use vga=771 and it gives me 1024x768 just fine..

but this is intelfb it has a special name. which makes me better than you!

I use this line under grub to boot my intel 82810E:
(custom compiled 2.6.16.7)
kernel /boot/vmlinuz26 root=/dev/hda6 ro dma acpi=force resume=/dev/hda7 devfs=nomount video=i810fb:vram:2,xres:1024,yres:768,bpp:8,hsync1:30,hsync2:55,vsync1:50,vsync2:85,accel

intelfb and i810fb are different fb drivers, which requires different boot options (video=intelfb:<options> and video=i810fb:<options> respectively.
i810 fb supports only different flavours og 810 and 81.5 chipsets. Intelfb supports 830 845 852 855 865 and 915 (I got a 915).

The options for the two drivers are quite different. Just grab the kernel docs and read linux/Documentation/fb/intel810.txt and linux/Documentation/fb/intelfb.txt.

About intelfb (but I guess also with i810fb), the documentation is not always accurate. Example given, if you use intelfb with a mobility card, then you can not pass the resolution in the vbe format, as an option (this is what the docs suggest), but you are required to use the old vga=<numeric>. If you do not pass the vga parameter, you get no framebuffer at all.

You never need both. E.g., the above quoted:
[code]
kernel /bzImage root=/dev/hda6 resume2=swap:/dev/hda5 video=intelfb:ywrap,mtrr,800x600-24@70 vga=789 splash=silent,fadein,theme:darch console=tty1 quiet ro
[code]
is redundant (and the option ywrap is not documented for intelfb).
