Not able to get Steam to start w/ Ubuntu 12.04

[Gunrunner]

First let me say I am brand new to unix in general. I installed Ubuntu on a new laptop and am attempting to get Steam to work. I have tried installing via USC as well as downloading from Steam website. I end up with the same error. When trying to open by clicking icon nothing at all happens, no process tree or anything. When I try and run in terminal this is what I end up with.

josh@mobilejc:~$ steam

I take it you're using a laptop and that steam has never worked?

Assuming all this I'm going to hazard a guess that this is related to nvidia's optimus graphics stuff, have a look here:

https://support.steampowered.com/kb_article.php?ref=6316-GJKC-7437
(NB the link right at the bottom about installing on a 64bit system!)

This is just a guess as I don't have anything with optimus myself.

You'll also want to make sure you aren't trying to use SLI as this is basically broken on Linux and a single one of your cards should be able to handle pretty much all games available on Linux anyway.

I was able to follow the directions on that page, then had to reinstall my GPU drivers. Seems like it did the trick. Steam is now updating correctly. Thank you for the help.

GOOD JOB!

As a nix new guy you just had a bit of a baptism of fire!

Optimus makes things a lot more complicated.
