Default Nvidia works - but only without AGP

Hello,

I've posted this problem into another forum and got no answer...so I will try it here

My environment: Debian SID (2.7.17), GeForce Ti4200, MB-Chipset Via Kt333, X.org-Server 7.1.0-2.
I've installed the nvidia-Linux-driver with the *.sh-Script (8774) and considered all advices. Before the sh-installer, I habe tried to install the debian-"nvidia-glx"-package with Kubuntu and Debian - the same problems but I have no logfiles anymore.

The installation of the nvidia-driver seems to be okay: nvidia-installer-log
In the X-Server-Logs there are always the following lines:
Code:
(II) LoadModule: "glx"
(II) Loading /usr/lib/xorg/modules/extensions/libglx.so
(II) Module glx: vendor="X.Org Foundation"
But later the same logfiles claim:

Code:
(EE) NVIDIA(0): Failed to initialize the GLX module; please check in your X...
The X-Server starts only with Options NvAGP "0" and "1".

With "NvAGP 1" i get an error in the X-Server-Log: X-Log NvAGP 1
The X-Server starts without AGP. The module "agpgart" is always loaded, but "nvidia-agp" isn't loaded. You can see in the X-Server-log that - when trying to load the module ("Use of NVIDIA internal AGP requested") - there is the message that glx is not loaded. I can load "modprobe nvidia-agp", but that doesn't help anything:
Code:
$ cat /proc/driver/nvidia/agp/status
Status:     Disabled
When i try "NvAGP 2" or "NvAGP 3", i get this X-Server-logfile: X-Log NvAGP 2/3
When I start the X-Server with these options, I only get a black screen and high cpu load. I have to reboot with the reset button. There appears the same error as in the other X-Logfile.

The graphic card doesn't seem to be the problem:
Code:
# cat /proc/driver/nvidia/agp/card 
Fast Writes: 	 Supported
SBA: 		 Supported
AGP Rates: 	 4x 2x 1x
I cannot find a module with "*glx*" in /lib/modules/kernel_version/. lsmod also doesn't show anything with 'glx'. I only can find:
Code:
# locate -i glx | grep module
/usr/lib/xorg/modules/extensions/libglx.so
/usr/lib/xorg/modules/extensions/libglx.so.1.0.8774
Here is my xorg.conf.

I have no idea what to do...so thanks a lot in advance for every advice how I can get the driver to start working.

If this problem persists with the 1.0-9625 driver, please generate and post an nvidia-bug-report.log.

Thanks,
Lonni

---------
1.0-9625:
----------

*) with NvAGP 1

I get a black screen, but no cpu load. So I can see the logs via ssh and I startet a nvidia-bug-report. I could not start with "startx -- -logverbose 5" because I start with
Code:
"/etc/init.d/wdm start"
the bugreport hangs when doing
Code:
"cat /proc/driver/nvidia/cards/0"
here some other output:
Code:
# lsmod |grep agp
via_agp                 9920  1
agpgart                30152  2 nvidia,via_agp

# lsmod | grep nv
nvidia               4711476  4
i2c_core               19904  5 nvidia,w83627hf,eeprom,i2c_isa,i2c_viapro
agpgart                30152  2 nvidia,via_agp
The Xorg-Log ends with
Code:
(**) NVIDIA(0): Use of NVIDIA internal AGP requested
*) with NvAGP 0: also black screen, no cpu-load

Xorg-Log ends with:
Code:
(**) NVIDIA(0): Use of AGP disabled per request
cat /proc/driver/nvidia/agp/status
and
cat /proc/driver/nvidia/cards/0
don't work, they hang.

So i uninstalled 9625 and reinstalled

--------
1.0-8774:
--------

*) "NvAGP 1"

Worked again without AGP. Here is the nvidia-bugreport
and the Xorg.log
"dmesg" tells "NVRM: not using NVAGP, an AGPGART backend is loaded".

The Xorg-Log has changed. After
Code:
Use of NVIDIA internal AGP requested
there doesn't occur an error because of "GLX" anymore (I don't know why),but agp still doesn't work. "lsmod" also doesn't show anything with "glx".
By the way, the fonts are deleted (??). The paths "/usr/share/X11/fonts/" have worked before, but now I cannot find these fonts anymore.

*) "NvAGP 2"

Again I got a black screen and high cpu load. I started a bugreport via ssh. The bugreport did work ecept the message "could not open display". Also in this Xorg.log, the GLX-errors don't occur anymore.

Here are the Xorg.log and the bugreport for "NvAGP 2"

Default Re: Nvidia works - but only without AGP

hm, I got no idea how to use this patchfile.

I guess I have to rename the patch into "NVIDIA_kernel-1.0-9625-NOSMBUS.diff" and then go to the directory usr/src/nv/ and execute an
Code:
patch -p1 < NVIDIA_kernel-1.0-9625-NOSMBUS.diff
When I look into the patchfile, I should search for "usr/src/nv/nv-i2c.c", Currently I have the 8774-driver running and I cannot find such a file. Do I first have to run the "NVIDIA-Linux-x86-1.0-9625-pkg1.run" before I can find this directory and the source file?

I'm sorry for this question, but I'm not very familiar with "patch"...never used it before.

Default Re: Nvidia works - but only without AGP

You need to extract the 1.0-9625 driver:
./NVIDIA-Linux-x86-1.0-9625-pkg1.run -x

then it can be patched:
# cd NVIDIA-Linux-x86-1.0-9625-pkg1/
# patch -p0 < ../NVIDIA_kernel-1.0-9625-NOSMBUS.diff.txt

and finally installed:
# ./nvidia-installer -s

Thanks,
Lonni

Default Re: Nvidia works - but only without AGP

Thank you, I did so (additionally I used "--x-module-path=/usr/lib/xorg/modules", I hope that's still up-to-date) and the driver 9625 is doing better now. But it seems to show exactly the same behaviour as the 8774.

9625 with NvAGP 1
nvidia-bugreport and Xorg.log

Hm, agpgart is always loaded and causes an error when Xorg tries to load the Nvidia-AGP-module (dmesg). Would it help to compile a kernel without "agpgart"?

Yes, you'd need to build your kernel without AGP support if you wish to set NvAGP to 1.

Default Re: Nvidia works - but only without AGP

I've tried a kernel without agpgart, but in this case (NvAGP 1) I get a black screen and high cpu load (Seems to be the same problem as with "NvAGP 2" / "agpgart"). I only can start the X-Server with "NvAGP 0".

Default Re: Nvidia works - but only without AGP

It looks like your system is not handling AGP speeds well.

Have you verified that you're using the latest BIOS for the motherboard?
If you boot with the noapic and/or acpi=off kernel parameters, does that help?

Thanks,
Lonni
