Drivers for NVIDIA 520M not working

Question

I know this is nominally a duplicate question, but I've read the other questions and haven't been able to fix my problem after many hours and attempts, so please don't delete it. Also, it seems like answers to other questions are dependent on certain situations. My situation being different from the others I found represented, here's my question.

Recently, I had Ubuntu 12.04 installed with Wubi, and it ran ok, though slowly and with occasional hangs. So I partitioned the drive and installed 12.04 in its own partition.

Now when I start it, I am stuck using 2D. I believe this is an NVIDIA bug.

My NVIDIA card is a GT 520M and my machine has Optimus.
Additional Drivers only displays my wireless driver.
Going to System Settings >> Details >> Graphics shows Driver:Unknown, Experience:Standard.

I downloaded the driver from the NVIDIA website, and ran the installer with no errors, except that the "distribution-provided pre-install script failed".

Rebooted and my screen was stuck at 640X480, which was fixed by editing /etc/X11/xorg.conf

However, I still was stuck in 2D, and nothing else had changed either.

A thread suggested Bumblebee. I tried that, and when I ran optirun firefoxI got a frozen blank screen.

After another suggestion, I checked the BIOS to try and disable Optimus.

I found and ran myriad other commands to try and fix the problem with no change.

I've just done a clean re-install of Ubuntu. From there, I:

• Installed all the updates
• Downloaded the NVIDIA driver
• Installed it
• Got screen stuck at 640X480, fixed in xorg.conf.

Recap:

• I can't get the NVIDIA drivers working
• I am stuck using 2D
• I'm an idiot

I think if the first one is solved, the second will naturally follow. If you need me to provide any other information, I'd be happy to.

From what I've seen in other threads, I think this information may help:

UPDATE: Per comment, installed Bumblebee. Am rebooting now to see if that helped.
Finished rebooting - no change.

UPDATE:
@Constantin: BIOS lists two options: "Switchable" & "Integrated". Tried them both, no go. I tried the directions you linked to - there is no change. nvidia-xconfig and nvidia-settings: done, done, and redone. No change.
Also worth noting I've since reverted all changes made following the instructions at that link.

Solution

OP posted:

Solution found! Seemingly by random chance, once after of the many reboots last night, I got Unity 3D and additional drivers now listed the two NVIDIA drivers. Then I was stupid enough to try and install those drivers - broke it.

However, that gave me hope, and a solution was found. I didn't get the NVIDIA drivers working, but I think I have working Nouveau drivers. Either way, Unity 3D is working perfectly.

Steps I took:

1. Yet another clean re-install.
2. Installed all the updates.
3. Opened terminal, ran apt-get purge nvidia-settings nvidia-current.
4. Reboot
5. And that got me Unity 3D and, I infer, working graphics drivers. Just in time too.

Hey, thanks for the guidance. :D I wasn't sure if I should have put it in the question itself or as an answer or both. Guess I have my answer now. Can I accept my own answer? Going to try.
