cannot get uvesafb to work [solved]

graysky · 2011-08-07 10:47:59

I'm trying to get uvesafb to work with the nvidia package. I installed uvesafb following the wiki. When I reboot after adding the v86d HOOK and rebuilding my initrsram images, the following doesn't exist:

/sys/bus/platform/drivers/uvesafb/uvesafb.0/vbe_modes

According to the docs, it should... thoughts?

I am booting with grub2 if that makes a difference and have disabled the keep gfxpayload option.

# cat /etc/mkinitcpio.conf
MODULES=""
BINARIES=""
FILES=""
HOOKS="base udev v86d consolefont autodetect sata filesystems"
COMPRESSION="lzop"

Not sure what I did wrong, but it's working now. I cleaned-up the uvesafb wiki article a bit. Hope someone finds it useful.

FYI, hook order is irrelevant. You can get the same mileage out of the v86d hook by skipping the hook entirely and just adding "/sbin/v86d" to BINARIES, "uvesafb" to MODULES, and "/etc/modprobe.d/uvesafb.conf" to FILES.

@falconindy - thanks for the info. I just organized the existing wiki and added a little... that was a carry over from the original article. Anyway, thanks.... NOW if you can tell me how I can get it to use 1920x1080x32 I would be very happy! Nouveau does this by default, but nvidia seems limited

If uvesafb doesn't offer it in that list, then it doesn't support it. nouveau takes advantage of KMS, which will always provide a native resolution framebuffer.

Are you aware of another framebuffer that will allow native resolutions AND work with the nvidia drivers?

It's impossible. To use resolutions that are not in the vbios you need to program the card natively. Any driver that does so will mess with the nvidia driver.

Thanks for the info; guess I'll live with 1280x800

Hi there someone can help me with mypost -> https://bbs.archlinux.org/viewtopic.php … 5#p1423845

Well the thing is

I think this are help for me ->

1 -> https://wiki.archlinux.org/index.php/Uv … stallation

Here i see :

$ cat /sys/bus/platform/drivers/uvesafb/uvesafb.0/vbe_modes
cat: /sys/bus/platform/drivers/uvesafb/uvesafb.0/vbe_modes: No existe el fichero o el directorio

Ok , how i can make that file because with

$ sudo mkdir -p /sys/bus/platform/drivers/uvesafb/uvesafb.0
mkdir: no se puede crear el directorio «/sys/bus/platform/drivers/uvesafb/uvesafb.0»: Operación no permitida

$ su

mkdir: no se puede crear el directorio «/sys/bus/platform/drivers/uvesafb/uvesafb.0»: Operación no permitida

I can't make manully that folder.
