Kernel 2.6.24 and UVesaFB

I have recently installed fbsplash from the AUR, and would like to use uvesafb, now included in the vanilla kernel. Now I am wondering why I can't get any higher than 640x480. When I try and put in a line with something else, it is just ignored. DonGiovanni has told me that it has been compiled in as a module and that it may be related to the problem. I don't want to compile my own kernel because it takes much too long. Anyone know how to fix this?

Re: Kernel 2.6.24 and UVesaFB

I just recently made an AUR package (named v86d) for using uvesafb as a module with the vanilla kernel. do makepkg, pacman -U then follow the instructions.

I'm not using fbsplash though so I can't guarantee anything.

Re: Kernel 2.6.24 and UVesaFB

I have problems with v86d hook. It seems that it fails to load uvesafb module during boot. I have 2.6.24 kernel from testing, hook and UVESAFB_PARMS are set. If I load uvesafb from comandline with proper options, it will switch to framebuffer and works well. Maybe you know what's wrong?

Re: Kernel 2.6.24 and UVesaFB

you have to add uvesafb to the MODULES line in /etc/mkinitcpio.conf too ... (and do mkinitcpio -p kernel26 again)

Re: Kernel 2.6.24 and UVesaFB

I just looked on the uvesafb website, and found this:

NOTE: The older versions of klibc seem to have problems with the new unified arches in the kernel (2.6.24). To avoid these issues, use klibc-1.5.8 or newer. Thanks to David Raison for pointing this out.

And Arch's klibc is out of date. Maybe this is related?

Re: Kernel 2.6.24 and UVesaFB

If it's worth anything I can't get uvesafb to work either. I have not ever been able to get it to work under archlinux. Has anyone been able to use uvesafb? I do have everything that is required. The right kernel patch with correct kernel params, v86d in mkinitcpio.conf hooks, uvesafb in mkinicpio.conf MODULES. This is so frustrating sad

Re: Kernel 2.6.24 and UVesaFB

I have it working, with three hooks (one for 915resolution-static to patch my bios, one for v86d, one for uvesafb). The options for the module are in /etc/modprobe.conf

Maybe this is the problem. For now I solved it by using modprobe.conf.

add uvesafb options to modprobe.conf

options uvesafb mode=1280x1024-32 mtrr=3 scroll=ywrap

my mkinicpio.conf

MODULES="uvesafb"
BINARIES=""
FILES="/etc/modprobe.conf"
HOOKS="base udev autodetect v86d pata filesystems"

Re: Kernel 2.6.24 and UVesaFB

Your recommendation worked! klibc is definitely the culprit.

Thank you.

Re: Kernel 2.6.24 and UVesaFB

huh? with my AUR package and core/klibc 1.5-3 and testing/kernel26 2.6.24-2, it totally works (unless one forgets to remove any 'vga=' parameter as I did in the beginning).

that said, the modprobe.conf + MODULES method seems much better to me. I'll fix that.

EDIT: AUR package updated.

Re: Kernel 2.6.24 and UVesaFB

I need to load uvesafb after the 915resolution hook, otherwise I am unable to get a 1280x800 framebuffer (this is my main aim in using uvesafb). So I need to have a uvesafb hook which loads the module after 915resolution. If I list uvesafb in MODULES, it does not work. On the contrary I realized that I do not need a v86d hook, I can list /sbin/v86d in BINARIES in mkinitcpio.conf.

So finally (just for reference for all the people with intel chipsets and widescrens which require 915 resolution):
1) compile 915 resolution statically (since it is going to be in an initramfs, it can not be linked to external libraries), with the following PKGBUILD:

pkgname=915resolution
pkgver=0.5.3
pkgrel=1
pkgdesc="A tool to modify the video BIOS of the 800 and 900 series Intel graphics chipsets"
arch=('i686' 'x86_64')
url="http://www.geocities.com/stomljen"
license=('custom')
depends=('glibc')
backup=(etc/conf.d/915resolution)
source=(http://www.geocities.com/stomljen/$pkgname-$pkgver.tar.gz 915resolution.rc.d 915resolution.conf.d)
md5sums=('ed287778a53d02c31a7a6a52bc146291' '4a5e9f60ba800883b361c9bb64ee0220'\
         '4df864a584173398f79293014766d575')

build() {
  cd $startdir/src/$pkgname-$pkgver
  export LDFLAGS="-s -static"
  make clean
  make || return 1
  unset LDFLAGS
  install -D -m755 915resolution $startdir/pkg/usr/sbin/915resolution
  install -m755 dump_bios $startdir/pkg/usr/sbin
  install -D -m755 ../915resolution.rc.d $startdir/pkg/etc/rc.d/915resolution
  install -D -m644 ../915resolution.conf.d $startdir/pkg/etc/conf.d/915resolution
  install -D -m644 LICENSE.txt $startdir/pkg/usr/share/licenses/915resolution/LICENSE.txt
}

2) write an initcpio hook for 915resolution. The following is /lib/initcpio/install/915resolution:

install ()
{
    MODULES=""
    BINARIES="/usr/sbin/915resolution"
    FILES=""
    SCRIPT="915resolution"
}

help ()
{
cat<<HELPEOF
  This hook patches the video BIOS for widescreen displays
HELPEOF
}

The following is /lib/initcpio/hooks/915resolution (adapt to your widescreen resolution):

run_hook ()
{
    msg -n ":: Patching the VBIOS..."
    /usr/sbin/915resolution 5c 1280 800
    msg "done."
}

3) write an hook to load uvesafb. The following is
/lib/initcpio/install/uvesafb

install ()
{
        MODULES="uvesafb"
        SCRIPT="uvesafb"
}

help ()
{
  echo "This hook loads uvesafb"
}

The following is /lib/initcpio/hooks/uvesafb:

run_hook
{
/sbin/modprobe uvesafb
}

4) install v86d from the AUR
5) add to /etc/modprobe.conf the options for uvesafb, so that it uses the resolution you have added to the bios with 915resolution:

options uvesafb mode=1280x800-32 scroll=ywrap

6) in mkinitcpio.conf, leave MODULES empty, and write:

BINARIES="/sbin/modprobe /sbin/v86d"
FILES="/etc/modprobe.conf"

7) add the 915resolution hook and, after it, the uvesafb hook to HOOKS in mkinitcpio.conf. Put them after the hooks of the hard disk and before those for the keymap, the resume from suspension and the filesystems
8) regenerate your initcpio
9) reboot and enjoy your widescreen framebuffer.

Re: Kernel 2.6.24 and UVesaFB

I have started a wiki page on uvesafb. What I have written is mostly focused on the interaction with 915resolution. Feel free to enrich and integrate with all the other aspects.

Re: Kernel 2.6.24 and UVesaFB

Hello, the problem for me is this: I have kernel26 (2.6.24.1-2) from Core (installed with pacman -S), and i have installed v86d from aur. So my framebuffer works only if i modprobe uvesafb manually after boot, in tty1, for example if i load it in gnome-terminal, it go in Segmentation Fault.

But the problem is that i would put uvesafb in the Initramfs, so i have changed few config's files.

This is my files config:

/lib/initcpio/hooks/uvesafb

run_hook ()
{
/sbin/modprobe uvesafb
}

/lib/initcpio/hooks/v86d
run_hook ()
{
/sbin/v86d
}

/lib/initcpio/install/v86d

install() {

    MODULES=" $(checked_modules "video/uvesafb") "
    SCRIPT="v86d"

    MODULES=$(echo ${MODULES}) #trim whitespace
    if [ -n "${MODULES}" ]; then
        MODULES="${MODULES}"
    fi

    add_dir "/dev"
    add_dir "/root"
    add_dir "/sbin"
    
    add_device "/dev/console" c 5 1
    add_device "/dev/tty1"    c 4 1
    add_device "/dev/zero"    c 1 5
    add_device "/dev/mem"     c 1 1
    
    add_binary "/sbin/v86d" "/sbin/v86d"
}

help() {
    echo "This hook sets up v86d, the userspace helper for uvesafb."
}

# vim: set ft=sh ts=4 sw=4 expandtab:

/lib/initcpio/install/uvesafb

# vim: set ft=sh:

install ()
{
    MODULES="uvesafb"
    SCRIPT="uvesafb"
}

help ()
{
cat<<HELPEOF
    This hook loads uvesafb
HELPEOF
}

/etc/mkinitcpio.conf

# vim:set ft=sh
# MODULES
# The following modules are loaded before any boot hooks are
# run.  Advanced users may wish to specify all system modules
# in this array.  For instance:
#     MODULES="piix ide_disk reiserfs"
MODULES="ata_generic ata_piix piix ide_disk ext3"

# BINARIES
# This setting includes, into the CPIO image, and additional
# binaries a given user may wish.  This is run first, so may
# be used to override the actual binaries used in a given hook.
# (Existing files are NOT overwritten is already added)
# BINARIES are dependancy parsed, so you may safely ignore libraries
BINARIES="/sbin/modprobe /sbin/v86d"

# FILES
# This setting is similar to BINARIES above, however, files are added
# as-is and are not parsed in anyway.  This is useful for config files.
# Some users may wish to include modprobe.conf for custom module options,
# like so:
#    FILES="/etc/modprobe.conf"
FILES="/etc/modprobe.conf"

# HOOKS
# This is the most important setting in this file.  The HOOKS control the
# modules and scripts added to the image, and what happens at boot time.
# Order is important, and it is recommended that you do not change the
# order in which HOOKS are added.  Run 'mkinitcpio -H <hook name>' for
# help on a given hook.
# 'base' is _required_ unless you know precisely what you are doing.
# 'udev' is _required_ in order to automatically load modules
# 'modload' may be used in place of 'udev', but is not recommended
# 'filesystems' is _required_ unless you specify your fs modules in MODULES
# Examples:
#    This setup specifies all modules in the MODULES setting above.
#    No raid, lvm2, or encrypted root is needed.
#    HOOKS="base"
#
#    This setup will autodetect all modules for your system and should
#    work as a sane default
#    HOOKS="base udev autodetect ide scsi sata filesystems"
#
#    This setup will generate a 'full' image which supports most systems.
#    No autodetection is done.
#    HOOKS="base udev ide scsi sata usb filesystems"
#
#    This setup assembles an ide raid array with an encrypted root FS.
#    Note: See 'mkinitcpio -H raid' for more information on raid devices.
#    HOOKS="base udev ide raid encrypt filesystems"
#
#    This setup loads an lvm2 volume group on a usb device.
#    HOOKS="base udev usb lvm2 filesystems"
HOOKS="base udev autodetect v86d uvesafb dsdt ide pata scsi sata usbinput keymap filesystems"

I have already tried to put uvesafb in MODULES, but the result is the same.

/etc/modprobe.conf

options uvesafb mode=1024x768-32

BUT when i run kernel dmesg report me this error:

-/init: 44: replace: not found
export: 44: bad variable name

....kernel panic!

the PKGBUILD of klibc is this

Re: Kernel 2.6.24 and UVesaFB

Well, the first behavior is normal, I think that you can not load the framebuffer from inside X (there should not be any difference between tty1 tty2 etc).

The second one seems a kernel bug, but I would try to simplify your setup (provided that you have not an intel chipset and so you do not need the trick with 915resolution which is discussed in the wiki article). Just list uvesafb in MODULES and /sbin/v86d in BINARIES, remove the two hooks and regenerate tour initramfs.

About the recompilation of klibc: itseems that for someone this generates a kernel panic. I think that this is totally unrelated to uvesafb: it is a problem between klbc-1.5 and the 2.6.24 kernel. Not a general problem though: the recompiled klibc works fine for me. You could try to upgrade to the testing version of klibc 1.5.8 (edit the PKGBUILD changing pkgver and _klibcbranch).

I have the same problem, albeit with a different kernel (...-zen/x86:64 with uvesafb compiled in). And I have tried with klibc 1.5.8 and it doesn't help: see this thread.

Re: Kernel 2.6.24 and UVesaFB

So, I have same thing when recompile klibc:

::Loading Initramfs
-/init: 44: replace: not found
-/init: 44: replace: not found
export: 44: bad variable name

....kernel panic!

After system restore - it's time to try build new version of klibc.
But it doesn't help us - if everything happens as on the previous post.

I know these errors...:( I just changed the _kernver variable in the PKGBUILD, is there anything else one should change in order not to get this error?

Re: Kernel 2.6.24 and UVesaFB

I think we must waiting for new klibc.

Re: Kernel 2.6.24 and UVesaFB

I'm getting this error.

uvesafb: Getting VBE info block failed (eax=0x4f00, err=-3)
uvesafb: vbe_init() failed with -22
uvesafb: probe of uvesafb.0 failed with error -22

I did everything according to the post-install instructions + I added /sbin/modprobe and /sbin/v86d to the BINARIES section of /etc/mkinitcpio.conf

Re: Kernel 2.6.24 and UVesaFB

LordRiden try to compile uvesafb as module in kernel and then to load it (modprove uvesafb) from tty1, and see dmesg ;-)

Hm, its working here. Stock kernel26 and the usual steps outlined in the wiki (modprobe.conf and Modules)


Haven't been here in a while. Still rocking Arch. smile

Re: Kernel 2.6.24 and UVesaFB

Do you use Arch i686 or Arch64? [For me it failed on Arch64]
