NVIDIA driver installed but undetected

My graphical environment in ArchLinux is currently refusing to start, due to the kernel not being able to recognize that the NVIDIA driver is installed. /var/log/Xorg.0.log repeatedly states:

(EE) Failed to load module "nvidia" (module does not exist, 0)

That's particularly weird because, at least, I could do a pacman -Syuu from command line, and upgrades for both the Linux kernel and the NVIDIA driver were present. Hoping that it would solve my problem, I promptly installed both. However, my problem still continues.

It should also be noticed that my screen has a resolution of 1366x768, but at boot time it is detected as 1024x768. When I boot, the screen's resolution changes just as the graphical environment starts, but in this case the change is happening during the boot time, still displaying the usual messages at boot from command line.

Re: NVIDIA driver installed but undetected

I think it's looking for:

/usr/lib/xorg/modules/drivers/nvidia_drv.so

Which of course should be installed by your nvidia package.

Re: NVIDIA driver installed but undetected

Did a downgrade fix your problem or did you get it working?

Re: NVIDIA driver installed but undetected

In the end, I had to settle with the Nouveau drivers. They're free software and just work, but they work about three times slower (given the FPS on several apps) and also they don't have OpenCL working, thus I can't use it for Bitcoin mining for now. So, in a way, a downgrade fixed my problem, albeit only partially. What can I do on my side to test a fix?

Re: NVIDIA driver installed but undetected

I'm  using  an NVIDIA GeForce GT 520.  Not  high-end but it should work with the latest drivers (in fact,  it did  until the last week).

Also,  if it helps: After checking journalctl, I  discovered that the kernel simply decided  not to probe the card several times in a row,  but I  still can't discover why (lack  of verbosity in the logs,  or I  just can't find in the right place).  Any tip would be greatly appreciated.

Re: NVIDIA driver installed but undetected

Try your luck, ive already helped a couple of guys to get a gt520 up and running with newer cpu's but with no luck!
A fellow had an older cpu with which the card worked, other than that other cards in the same and different series work fine..
try blacklisting...

Have you installed X server on arch linux?

Re: NVIDIA driver installed but undetected

It should be noticed that I already had X working, NVIDIA working and everything in place just a week ago. Downgrading is no longer a possibility, since the dependencies require downgrading the kernel itself to work. I'll try my luck with the LTS version of the kernel and post what happens.

Re: NVIDIA driver installed but undetected

I'm back! The change to LTS did the trick! However, I noticed something curious. Accidentally I booted back to the normal kernel (with both nvidia and nvidia-lts installed), and surprisingly enough, NVIDIA started working again (seemingly just because the LTS module was present). That makes me think that there was a regression related to the kernel, since nvidia and nvidia-lts have essentially the same binary.

Re: NVIDIA driver installed but undetected

Is it possible that you pulled down a kernel update and didn't reboot?

Re: NVIDIA driver installed but undetected

No way. As an user that turns off its computer every night, I've had plenty of opportunities to reboot it this week. Also, I'm always careful to do a mkinitcpio and a grub-mkconfig after switching kernels.
