I'm really struggling to get fbsplash working with my motherboard. It's a Dell T7500 Xeon with Nvidia Quadro FX 580 graphics card and whilst the nvidia drivers seem to work, I can't get fbsplash to function.
lspci shows
Code:
03:00.0 VGA compatible controller: NVIDIA Corporation G96GL [Quadro FX 580] (rev a1)

and dmesg gives me
Code:
[    9.648525] nvidia: module license 'NVIDIA' taints kernel.
[    9.648538] Disabling lock debugging due to kernel taint
[    9.657627] vgaarb: device changed decodes: PCI:0000:03:00.0,olddecodes=io+mem,decodes=none:owns=none

[   29.358184] nvidia 0000:03:00.0: irq 93 for MSI/MSI-X


I've set up the kernel following this page
http://wiki.gentoo.org/wiki/Uvesafb
and
http://wiki.gentoo.org/wiki/Fbsplash
and my grub config is
Code:
title Gentoo Linux Current

root (hd0,2)
kernel /boot/kernel-x86_64-3.14.0-gentoo root=/dev/sda4 splash=verbose,fadein,theme:gentoo video=vesafb:1280x1024-32,mtrr:3,ywrap quiet CONSOLE=/dev/tty1
initrd (hd0,2)/boot/initramfs-bootsplash

and I generated an initrd image like this
Code:
splash_geninitramfs --verbose --res 1280x1024 --generate /boot/initramfs-bootsplash gentoo
o Creating directory structure..
o Copying //sbin/fbcondecor_helper..
o Copying themes..
  - gentoo
o Creating initramfs image..

but all I ever get for a console or boot screen seems to be a plain black and white 640x480 screen. When I test splash in a console
Code:
splash_manager -c demo -t natural_gentoo -m s --steps=100

it works, but resolution should be 1280x1024 as specified in grub. How do I get the nvidia card to display the consoles at 1280x1024, the Xorg display doesn't seem to have a problem with it?
I get a few errors during boot but they're too quick to read and don't appear in any logs as far as I can tell. Can anyone give me any pointers because I'm utterly confused by now!

Hello,

assuming you have configured "uvesafb" according to what is indicated in the wiki, i think you have an error in the kernel command line in grub.

Change:

...video=vesafb:1280x1024-32 ... by ... video=uvesafb:1280x1024-32 ...

and try.

Best regards.

For Vesafb, the resolution is pass with the vga= kernel parameter. For 1280x1024-24
Code:
vga=0x31B video=vesafb:mtrr:3,ywrap
