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
(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?
