Unable to acquire AGP, error "xf86_ENOMEM"

Hi all,

I have no 3d acceleration out of my Radeon 9800SE. To business: the relevant part of my XFree86.0.log is:

Code:

I have performed the following actions (all as root):

(1) I have recompiled my kernel, enabling /dev/agpgart and MTRR, and disabling DRI and kernel debugging.

(2) I have obtained the appropriate driver from www.ati.com and installed it: "rpm -iv --force fglrx-4.3.0-3.9.-.i386.rpm"

(3) I have run fglrxconfig. I had to copy the ModeLines from the XF86Config-4 that Mandrake 10 created for me on install, as the ModeLines in the XF86Config-4 that fglrxconfig created did not work.

(4) I have typed the following:

Code:

cd /lib/modules/fglrx/build_mod
chmod u+x make.sh
./make.sh
cd ..
chmod u+x make_install.sh
./make_install.sh

(5) I have restarted my machine to make sure all modules are loaded correctly.

Nevertheless, I still have no 3d acceleration.

Some information about my machine. I am running Mandrake 10 with a 2.6.3 kernel I installed from the mandrake discs and compiled myself. My PC has an Asus a7n8x-e deluxe motherboard which has the nvidia nforce2 chipset. My graphics card is a Sapphire ATI Radeon 9800SE. The edited highlights of the output from lspci are as follows:

Code:

        Capabilities: <available only to root>

When I google, I find that the steps I have already followed are sufficient for most people. However for me something further is required. I would be very grateful if someone could point out to me what that might be.

TIA

you need to un-comment the line in your /etc/X11/XF86config

Code:

load "DRI"

vasudevadas · 06-02-2004, 01:01 AM

Already does it:

Code:

Section "Module"

# This loads the DBE extension module.

    Load        "dbe"   # Double buffer extension

# This loads the miscellaneous extensions module, and disables
# initialisation of the XFree86-DGA extension within that module.
    SubSection  "extmod"
      Option    "omit xfree86-dga"   # don't initialise the DGA extension
    EndSubSection

# This loads the Type1 and FreeType font modules
    Load        "type1"
    Load        "freetype"

# This loads the GLX module
    Load        "glx"   # libglx.a
    Load        "dri"   # libdri.a

EndSection

Are you on an Athlon processor?

I've gotten that error before..
I'm not sure if the newest ATI drivers include these, but I had to use the following patches before building the fglrx module:

fglrx-2.6-vmalloc-vmaddr.patch :

Code:

    (AMD claimed that CPU cache behaviour for such pages is not specified.)

The first is if you're running with a 2.6 kernel.

Run these with this command...

Code:

patch -p1 < patchname

--Shade

PS- google on the xf86_ENOMEM error, and you'll see some other hints at solutions.

Yes I am using an Athlon. I'll look into that as soon as I get home from work. I do know for certain that the second patch is already included. Thanks.

I resolved the problem and got it to work, sort of. Firstly I had made the mistake of configuring the video driver to use its internal AGPGART, whereas I should have specified UseInternalAGPGAP "no" so that it uses the kernel module instead. Secondly, I needed to use the nvidia chipset kernel driver: modprobe nvidia-agp did the job, although I compiled it into the kernel for convenience.

However, I have a new problem. Since it looks to be unrelated, I have started a new thread about it:

Many thanks for all your help.
