I rescently installed Ubuntu 14.10 (AMD64) on my ASUS X53U (CPU: Brazos Dual Core E350 1.6 GHz GPU: HD 6310M, 3GB RAM) I downloaded Steam from the website, installed it, got some errors and managed to ruin everything (low res, really slughish) by just pasting commands into the terminal that seemed to make sense while I actaully had no idea what I was doing.
So I "threw everything out the window" and installed the OS fresh again.
Everything is fresh. All I have done is run the software updater and installed Grub Customizer so I can access Windows 7. (don't even have Steam installed)
So what are the exact steps on setting up all the OpenGL stuff and getting TF2 to run? (simply things to paste in the terminal would be best)
The most helpful person gets a game of their choice on Steam for under 10 euros.
I know that it should be possible to find everything myself but I just don't have the time or intelligence for that. That's why I would rather just have someone else spend time helping me and buy them a game for their efforts.

For the drivers, search for the "Additional Drivers" program, you should find it somewhere in the "Software Sources" setting, IIRC.
For Steam, open the Ubuntu Software Center and search for Steam, then install it from there.
No commandline usage is needed for these two tasks.

Found Additional Drivers using Search your computer and online sources. It opened a window called Softwere & Updates.
I found Steam using the software centre but there is no install button and clicking More Info gives me this: There isn’t a software package called “steam” in your current software sources. That's why I downloaded Steam from the website before. Should I do the same again? I also read somewhere that there is a terminal command for installing Steam; maybe I should use that? I don't know it by the way.

The previous reply took long to show up so I wrote an another one and now I have no idea how to delete this

The steam package is part of Ubuntu's multiverse repository, it may be possible that you have to enable that first in the Software & Updates Windows. If that doesn't help install the Gdebi program, this will allow you to easily install the Steam package you have downloaded.

Software restricted by copyright or legal issues (multiverse) is already ticked in Software & Updates.

I downloaded Steam from the website and used GDebi Package Installer to install it. It installed A LOT quicker than by using Ubuntu Software Centre!

I opened Steam and it gave me this error message:
OpenGL GLX context is not using direct rendering, which may cause performance problems.

Previously, I tried using glxinfo | grep to see if I have direct rendering on. Like it asked, I installed glxinfo and found out that it WAS actually on. So I'm assuming that it would be the same this time too
From what I read before, I should just ignore the error but it would still be nice if I could get rid of it...

I'm assuming that it doesn't really matter when I download TF2 so that's what I did.

Trying to launch it gives me this error: Could not find required OpenGL entry point 'glGetError' Either your video card is unsupported, or your OpenGL driver needs to be updated.

I tried doing the thing where you remove libgcc_s.so.1 from /home/username/.local/share/Steam/ubuntu12_32/steam-runtime/i386/lib/i386-linux-gnu and restarting Steam but that didn't change anything and I put it back where it was.

I looked at the system requirements and it said I need AMD 12.11 drivers and OpenGL 2.1. How do I know if I have them and if not, how do I get them?

Steam needs 32 bit libraries for your graphics driver installed, since Steam itself is a 32 bit program. You can enable the use of 32 bit libraries with
You will have to reinstall the drivers afterwards, but since I am not using Ubuntu I am not sure if this is sufficient.

I don`t know why but I decided to try using the non open source drivers and that got it working. Loading times are horrible, however. Are the open source drivers better? Is it even worth trying to get them working?
Sorry for the time it took to respond.

From what I have heard (I don't use AMD graphics for gaming anymore, guess why) the open source driver delivers a lower framerate, but the framerate is more constant. Many users complain about microstuttering when using the proprietary drivers for Source engine based games. However, I doubt that the driver in use a significant influence on loading times.
