Recently, I finally got the official drivers for my NVIDIA 560 Ti card installed on Ubuntu 14.04 (hooray) However I started looking into installing Steam and I'm getting segmentation errors when I try to run the software. I tried installing 32-bit libs and it seemed like they weren't available or they were already installed. Upon further investigation, I found that a solution is to install the proprietary drivers, install steam then switch back to the other drivers. I'm not really sure what "proprietary drivers" are in all honesty. Has anyone gone through this process that could provide some insight here?

(I installed the official 64-bit driver from the NVIDIA site for my 560 Ti just for reference. And the Ubuntu version installed is 64-bit as well)

Update:

This is the error text I get when trying to run steam after installing it via the ubuntu store.
