My laptop model is ASUS F550CC with NVIDIA 720M (not optimus) graphics card.
I'm confused with what method should I really use to install NVIDIA 720M in my Ubuntu. Should it be via PPA, Additional Drivers or NVIDIA's website?
What I did was to install the two NVIDIA drivers that appeared in the Additional Drivers upon fresh Ubuntu installation. With the image file attached, it can be seen that Ubuntu cannot detect my graphics card.
I also installed mesa-utils to run glxinfo but I got error messages as depicted in the image file attached below.
When I run
lspci | grep NVIDIA, it showed my driver. I'm really confused. One says it cannot be detected, another said it can. What should I believe in? Also how do I really test if NVIDIA is correctly installed (e.g. running some sort of test program)? Also did I installed it correctly?
Here is the detail on how I installed my Ubuntu upto NVIDIA:
- Installed Ubuntu 12.04 x64 without installing updates upon fresh installation. (For faster Installation)
- Installed one of the proprietary drivers and restart.
- Installed the other one and restart.
- Installed mesa-utils.

Running sudo nvidia-settings shows the NVIDIA GUI
I also run sudo nvidia-xconfig and sudo reboot
Now I got this ugly video resolution. I also run glxinfo again but got the same error message but the details does not display unknown anymore but none at all.
Here is the /etc/X11/xorg.conf after I executed sudo reboot..
