nvidiia: "Failed to load module "nvidia-1.0-9746"

[StefanJ]

I've searched for cases similar to what I'm seeing. I found some promising leads, but not seem to exactly apply in my case.

My MythTV box was running fine under Core 5 2.6.18-2257. I was using the "nvidia" driver; version 7554. There were a few problems: When leaving Mythfrontend the nvidia drivers reloaded. Also, trying to look at the OpenGL configuration options caused a restart.

I did a yum update yesterday and ended up with 2.6.19-1.2288.fc5.

X failed to load as I had things installed..

* I can run under the "nv" driver set, but this doesn't allow the video out to work.

* Running under the "nvidia" set results in a 7554 module not loading during boot.

* I used "yum" to install the 9746 vintafe drivers. I believe I have the complete set, although "yum install kmod-nvidia" didn't seem to do anything:

No Match for argument: kmod-nvidia
Nothing to do

If I specify the 9746 set in the Display:Hardware:Video Card driver selection, X fails to initialize:

(EE) LoadModule: Module nvidia-1.0-9746 does not have a nvidia-1ModuleData data object.
(EE) Failed to load module "nvidia-1.0-9746" (invalid module, 0)
(EE) No drivers available.

Fatal server error:
no screens found
odule. If
(EE) NVIDIA(0): you continue to encounter problems, Please try
(EE) NVIDIA(0): reinstalling the NVIDIA driver.
FATAL: Module nvidia_1_0_9746 not found.
(EE) NVIDIA(0): Failed to load the NVIDIA kernel module!
(EE) NVIDIA(0): *** Aborting ***
(EE) Screen(s) found, but none have a usable configuration.

What exactly am I missing? Which driver shold I be shooting for and trying to fix: The "nvidia" selection, or the one that names a particular driver version?

Thanks,

Stefan

You didn't mention what card you're using. Is it one of these: http://forums.fedoraforum.org/showthread.php?t=144468

[StefanJ]

Ah, that's a pretty basic thing I should have mentioned.

It's detected as a "NV 34 [ GeForce FX 5200]"

I looked through the thread you'd mentioned earlier today, and didn't want to risk loading the older drivers; I'm pretty sure my card is supported by the current stuff.

If you're aware of another thread where this is covered, point away. I thought I did my due diligence, but couldn't come up with a discussion that matched this scenario.

How exactly does "yum install kmod-nvidia" work? Is that package kernel-non-specific, or does it somehow determine which version to install without parms?

Thanks,

stefan

The kmod-nvidia should handle it unless you're running a legacy card (like I am) then you've got to opt for the 96xx version. Fortunately, one of our Community Managers, Firewing1 is maintaining the kmod-nvidias and will probably jump in here with a fix when he's available. Of course, you can also shoot him a quick Personal Message but first I'd double-check the threads he's started on Nvidia. Just open up that Search > Advanced Search and then plug in 'nvidia' and choose threads Started By firewing1. That will give you some reading and probable solutions. He does an excellent job of keeping those threads current too.

i make impossible happen , look at this .

Sa6oook, please start a new thread for your problem. As info, rpm is rejecting your removal since you've included the full description and not what it's known by in the system. You can find it by 'locate kmod-nvidia-legacy' or something like that and see how it's called; then use the rpm -e on the actual name. (hint: it's probably called "kmod-nvidia-legacy-1.0.7184-3.2.6.19_1.2895.fc6.i686" )

Bob:

Thanks for the head's up on firewing1's posts. I'll start browsing.

In addition to a fix, I'm interested in what went wrong. I understand that new kernels need new drives. After I booted to the new kernel, and had to reconfigure X to use nv (the common denominator drivers that always seem to work) I ran:

yum -y install nvidia-graphics9746-kmdl-$KVER
yum -y install nvidia-graphics9746-libs nvidia-graphics9746

($KVER expands to the kernel version)

The first package is described, in the Fedora Add/Remove Software GUI, as "kernel module for NVIDIA graphics architecture support." But obviously it didn't have what it takes to cut the mustard!

What does kmod-nvidia consist of? Does it install the "Module nvidia_1_0_9746" that is mentioned in the X error log?

Thanks

OK. This is interesting.

I tried, for the first time since this morning, selecting the "nvidia" driver. I also rebooted. My aim was to look for the exact name of the module that wasn't found on boot.

Well, there was no such message, and a NEW nvidia driver splash screen appeared. Green, rather than white.

I suppose that one of the "yum install kmod-nvidia" runs I ran actually did something. I checked the "nvidia x server settings" menu and sure enough, I'm now running 1.0-9746.

HOWEVER . . .

If I start mythtv, the x-session ends. I end up back at the log-on splash screen.

But if I try to check the "OpenGL" section of the "KInfoCenter", the same session-killing thing happens.

This is essentially a nastier version of the behavior that spurred me to update in the first place. The x session was dying when I EXITED MythTV.

I suspect I've found a OpenGL bug.
