 Posted: Thu Jul 21, 2005 11:05 pm Post subject: Cannot get framebuffer working [solved] |
 |
|
Hi,
I am trying to set up a framebuffer and I just can't get it working. I have compiled my kernel with vesafb support. And I used splash_geninitramfs and followed the steps on http://dev.gentoo.org/~spock/projects/gensplash/archive/gensplash-in-5-easy-steps.txt .
This is what I have in my menu.lst
| Code: |
default 0
timeout 5
splashimage=(hd0,1)/grub/splash.xpm.gz
title=Gentoo Linux 2.6.12-r6
root(hd0,1)
kernel /kernel-2.6.12-gentoo-r6 root=/dev/hdb4 video=vesafb:1024x768@85 splash=silent,theme:Emergence
initrd /boot/fbsplash
|
Does anyone see anything wrong with this?? Just let me know if you need any more information.
Thanks!
Evan

ok,
I followed those a bit closer and when I reboot I get this output...
| Code: | Failed to open /dev/fb0 or /dev/fb0 for reading.
Can't open config file /etc/splash/emergence/0x0.cfg
Failed to load image (null).
Can't open /dev/fb0 or /dev/fb/0.
|
Any ideas?? |

Have you upgraded to splashutils-1.1.9.7 and rebuild your initrds?
Do you have a recent version of udev?
Could you please tell us your full grub kernel line?
emergence have been removed from the core splashutils package. You might want to emerge media-gfx/splash-themes-* to get it.
Also, you should read the wiki. It has been recently updated with the new way for installing Gensplash. |

I just emerged splashutils-1.1.9.7 today. I think I rebuilt my initrds, is that what running splash_geninitramfs does?

I am really new to this, i'm not really sure what udev is. So how would I check it?

I realized that emergence wasn't their, so I have changed it to Emergance which is there, but it still doesn't work.
Thanks!

After much reading and testing things out I managed to get a framebuffer going. I still have not been able to get a boot splash working though.
I also tried using qingy, and I am getting an error with that which might have something to do with it. In the instructions for setting up qingy it says I need to run fbset. I don't have that command!?! What have I done wrong???
Thanks!

I have the same problem.
I use a 2.6.12-nitro-r5 with genkernel (3.3.5)
udev is version 058 on my system (but genkernel use a 054)
splashutils 1.1.9.7 (recently re-emerge for the 2.6.12-nitro-r5 kernel)
my genkernel command line for generate the initramfs is :
| Code: | | genkernel --gensplash=default --lvm2 initrd |
my lilo entry is :
| Code: | image = /boot/kernel-genkernel-x86-2.6.12-nitro5
root = /dev/ram0
label = "Gentoo-R4N"
read-only
append = "init=/linuxrc real_root=/dev/hda7 splash=silent,theme:default video=vesafb:1024x768@60 CONSOLE=/dev/tty1 quiet dolvm2 udev"
initrd = /boot/initramfs-genkernel-x86-2.6.12-nitro5 |
so, when my system is off, the content of /dev have no /dev/fb0 entry.
When adding one, the problem is steel here, and udev remove my /dev/fb0!
How the initramfs can access to /dev/fb0 at the early start ? 
I try fbset
first, on a working system (with no splash) :
| Code: | dekarion / # fbset -i
mode "1280x1024-75"
# D: 135.007 MHz, H: 79.981 kHz, V: 75.029 Hz
geometry 1280 1024 1280 1024 32
timings 7407 248 16 38 1 144 3
hsync high
vsync high
rgba 8/16,8/8,8/0,8/24
endmode
Frame buffer device information:
Name : VESA VGA
Address : 0xd8000000
Size : 16777216
Type : PACKED PIXELS
Visual : TRUECOLOR
XPanStep : 0
YPanStep : 0
YWrapStep : 0
LineLength : 5120
Accelerator : No
|
I adding this section to the non-existent /etc/fb.modes file of the other system :
| Code: | mode "1280x1024-75"
# D: 135.007 MHz, H: 79.981 kHz, V: 75.029 Hz
geometry 1280 1024 1280 1024 32
timings 7407 248 16 38 1 144 3
hsync high
vsync high
# rgba 8/16,8/8,8/0,8/24
endmode |
(rgba line is comment because of syntax error with fbset)
after booting on the other system, I try "fbset -fb /dev/fb0 1280x1024-75" but he insult me because /dev/fb0 does not exist.
I create/force it like that :
| Code: | | mknod -m 600 /dev/fb0 c 29 0 |
but with the same fbset command, fbset told me that it can't open /dev/fb0
on the working system I have a /proc/fb0 directory, not on the other system ... |

Try adding vga=0x318 to your append line.
So it would look something like this:
| Code: | image = /boot/kernel-genkernel-x86-2.6.12-nitro5
root = /dev/ram0
label = "Gentoo-R4N"
read-only
append = "init=/linuxrc real_root=/dev/hda7 splash=silent,theme:default video=vesafb:1024x768@60 vga=0x318 CONSOLE=/dev/tty1 quiet dolvm2 udev"
initrd = /boot/initramfs-genkernel-x86-2.6.12-nitro5 |
This made it work for me. |

the vga option is for vesa, and I use vesa-tng 
without any video option (let the default mode), that don't work too 
I will try to use vesa mode instead of vesa-tng ... |
