Got a HBS (y'know, Honkin' Big Server, one o' them technical terms), a Dell 720 with two Tesla GPUs. I updated the o/s, 6.5, and I cannot get the GPUs recognized.

I've yum removed the kmod-nvidia I had on the system, nouveau is blacklisted, and when I reboot, lsmod shows me nvidia loaded, which modinfo tells me looks like the one I built.... but enum_gpu, which is from a CUDA group, builds... but can't enumerate the GPUs (how we wake them up for the

see the /dev/nvidia*, and they're a+r, a+w.... Oh, and selinux is permissive.
Anyone got a clue? If I can't get this working, I'm going to have to downgrade the system several kernels.
Do you have an /etc/X11/xorg.conf file or something in /etc/X11/xorg.conf.d/ that actually name nvidia and not nv as the driver?
Nope - nothing there.
When you run the ./NVIDIA<version> command to build the driver, one of the last steps is to have it "automatically update your configuration file" .. select yes for that and it should create an xorg.conf file that will use the nvidia driver.
a) I didn't have that before - did kmod-nvidia handle loading the correct one *without* an xorg.conf? b) Do you think it'll do the right thing - this *is* a headless server.
And a general question: what *does* kmod-nvidia do - is it different than, say, setting up a flag, or a script to notice that you're booting a new kernel, and run the proprietary installer -a -s?
Are you connecting to the server to do X related things remotely ... and therefore need NVIDIA drivers for that?
I'll let one of the elrepo guys explain their RPM.
