Steam won't start on Ubuntu 16.04 LTS 64-bit with AMD GPU

Steam on Ubuntu 16.04

I run two PC's with AMD GPU's and with the release of Ubuntu 16.04 LTS, I have been unable to run steam using the default grpahics drivers that come with steam. Clicking the steam icon, just made it flash for a little bit, but steam never started. To get more detail, I tried running steam from the command-line, and I got the following error message:

jordan@jordan-H8DI3:~$ steam

I had to hit CTRL+C in order to get out of it. After some research, I was able to get steam running with the following command:

LD_PRELOAD='/usr/$LIB/libstdc++.so.6' DISPLAY=:0 steam

I haven't tried a lot of games through steam after starting this way, but the ones that I did try have run just fine... so far.

Steam doesn't like the new AMD graphics drivers in Ubuntu 16.04. To get round this until either Ubuntu, Valve or AMD fix the problem, you will have to use the terminal command you list above.
