radeonfb syntax

How do you use radeonfb? I can't get it to work. The syntax is incorect in modprobe.conf? I tried "options radeonfb 1680x1050-32@60" and "options radeonfb mode=1680x1050-32@60". It says incorrect syntax.

Re: radeonfb syntax

It picks the highest resolution when you load it without any options. That works for me.

On boot, this syntax here works: http://thesapphirecat.iwarp.com/present … eonfb.html

Re: radeonfb syntax

I fails to se how that works since it's a module, not static. This is why it has to be put in modprobe.conf.
Paste you grub menu please.

Re: radeonfb syntax

The syntax is  mode_option=1680x1050-32@60
I just got radeonfb working with two methods.

1)
using self compiled kernel with radeonfb compiled directly into the kernel

- just add video=radeonfb:1680x1050-32@60 to the kernel commandline in the grub config file

2)
using Arch-stock kernel and initrd-image

add the module to the MODULES="" line in /etc/mkinitcpio.conf

MODULES="radeonfb ..."

add a line with the options for the module to /etc/modprobe.conf

options radeonfb mode_option=1680x1050-32@60

regenerate the initrd-image

mkinitcpio -g /boot/kernel26.img

Re: radeonfb syntax

video=radeonfb on the kernel line works for me - no options required, same as vogt above.

Re: radeonfb syntax

video=radeonfb on the kernel command-line does only work (for me) if the radeonfb is compiled into the kernel and not as module like in the arch-stock kernel.

I need the options because without them the framebuffer is started with the lowest color-depth and I want the highest. wink

Re: radeonfb syntax

Sorry, forgot to mention that I have the radeonfb module in my initrd image.

Re: radeonfb syntax

works for me with video=radeonfb in kernel append line and radeonfb in mkinitcpio.conf + rc.conf.

only the first part seems to fail. i cannot see the 2(dualcore) Arch logos and the initrd messages are shown in ugly 80x font though the initrd shows the modul loading.

Re: radeonfb syntax

Same for me - the first few seconds are ugly, then the module gets loaded and all's well.

Re: radeonfb syntax

You shouldn't need to put the video option in the grub file, since radeonfb isn't built-in, unless you are using a custom kernel.
I've just followed SiD's instructions and it's working just fine. Although I don't see the arch logo.....don't know why hmm

Re: radeonfb syntax

Hello

What do you think about adding this information to the wiki? I don't think there's something in the wiki about this yet. I stumbled here by pure coincidence. The framebuffer option is really great. I used the vga=xxx option in the grub menu but the disadvantage is that the refresh rate keeps stuck at 60 Hz, which isn't very eye friendly. With the framebuffer option mentioned here I was able to set the display refresh rate to 85 Hz.

It's a wiki - add anything you want.

Re: radeonfb syntax

I'm not quite sure where this topic does belong to: Kernel compilation, Grub, Post Installation Tips, own topic...? Any suggestions?

For a start I would just copy and paste the the information SiD gave.

A list with the available frame buffer drivers and the supported chip sets would also be very nice...

Re: radeonfb syntax

Did a seach for radeonfb on the wiki and found only a slight reference in the ATI article, so I take it you didn't get far, BertiBoeller?

Anyway, SiD's second option works seemslessly (knock on wood) for me. However, the default font is quite small for my myopia. Can anyone suggest, name and indicate settings for a nicer, bigger one? I'm on 1280x800, same as some previous posters....

EDIT: FOUnd the wiki entry and the terminus package in the repos. Was a bit lazy there, I guess. Still, the terminus font is a bit too uhm 'edgy' at high resolutions and the sun12x22 is a bit too 'serify'... the quest goes on..

Re: radeonfb syntax

Thanks SiD, your 2nd method worked perfectly here (no syntax in menu.lst). Same problem here though, can't see the Arch logo ^^

Re: radeonfb syntax

Hi!
I already tried all the ways to put radeonfb working at 1280x800 and nothing! The module is always loaded but it never does anything.
My card is an HD2600 on a Toshiba A200-1GB laptop.
Anyone has other way to put that working?

Thanks in advance!

I don't think radeonfb supports recent GPUs
