Can't Open Steam in 16.04

[El Zoido]

Just in case you do have an AMD GPU:
It's a known issue with the open-source drivers (which are now used by default since fglrx is not supported in 16.04) and Steam.
Not sure who's to blame here, but there are various solutions to the problem available.

I'm starting Steam on my machine via (either in the console or by creating a custom launcher):

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

There might be better solutions, but this at least starts Steam for me.

It worked, thanks! Is there a new AMD driver I need to install for my radeon GPU?

No, not really. I think that the problem has to be fixed by Steam, but they probably would say it's Ubuntu's problem.
That's usually how those things go

Anyway, I'm not even entirely sure what's causing the problem exactly, I just copied the solution from elsewhere. Apparently some libraries are not fully compatible or not loaded correctly when starting Steam using the open source drivers.

Yup. Neither probably want to use their resources to fix it.

Random question: I'm also having problems running some graphic intensive programs in Virtualbox. Could this be related?

Thanks, that worked perfect for me. Wasn't able to get Steam installed properly, but that code did the trick!
