Error: OpenGL GLX context is not using direct rendering

[ghost]

Hello, I've installed this on Crunchbang on two different computers but it doesn't work on one. I get this output:

The computer that works uses integrated Intel graphics. The one that doesn't has an i7-4770k and AMD Radeon HD 7950.

@Fangz17 Does apt-get -t unstable install fglrx-driver work now?

[ghost]

@GhostSquad57 Nope

@Fangz17 apt-cache policy glx-alternative-fglrx

@Fangz17 WAIT! The problem is with your /etc/apt/sources.list file!

Change deb http://ftp.uk.debian.org/debian unstable main non-free to deb http://ftp.uk.debian.org/debian unstable main contrib non-free

Then apt-get update and then try to install fglrx-driver

[ghost]

@GhostSquad57 Urgh, come on, that was the issue?

Aaand Segmentation fault.

[GhostSquad57]

@Fangz17 What's segfaulting? Steam?

[ghost]

@GhostSquad57 Yeah

[GhostSquad57]

@Fangz17 But to confirm that the drivers are working, glxgears

Let me know the output of glxgears

[ghost]

@GhostSquad57 Yes, they're working.

[GhostSquad57]

@Fangz17 YEEEEES!

Now, on to Steam. Install libgl1-fglrx-glx:i386 and then try launching Steam

[ghost]

@GhostSquad57 Segmentation fault still.

[GhostSquad57]

@Fangz17 OK. Try installing libgl1-mesa-dev libfglrx:i386

[ghost]

@GhostSquad57 No...

This is what I've got installed so far:

fglrx-atieventsd                install
fglrx-driver                    install
fglrx-modules-dkms              install
glx-alternative-fglrx               install
libfglrx:amd64                  install
libfglrx:i386                   install
libfglrx-amdxvba1:amd64             install
libfglrx-amdxvba1:i386              install
libgl1-fglrx-glx:amd64              install
libgl1-fglrx-glx:i386               install
libgl1-fglrx-glx-i386               install

What should I have?

[GhostSquad57]

@Fangz17 Looks like all the necessary files are installed.

Does STEAM_RUNTIME=1 steam work?

[ghost]

@GhostSquad57 YES!

[GhostSquad57]

@Fangz17 WOOHOO!!!!

[GhostSquad57]

@Fangz17 I knew eventually we would solve this, thank you so much for sticking till the end.

Happy Steamin'
