Solution to Black Screen in TF2

[Teisei]

I just wanted to share my solution to the black screen problem in TF2. I'm using Xubuntu 12.10 64-bit with 310 series Nvidia drivers (GPU = GTX460M).

1) Open a terminal and type: sudo nano /usr/bin/steam
2) Add the following lines after "#! /bin/bash":
export LANG=C
export LC_NUMERIC=POSIX
3) Save (CTRL-O + Enter + CTRL-X)
4) Launch Steam

Just "export LANG=C" alone didn't help me, but for some it has done the trick. I got my idea from Limited Beta section, but since I'm not in the beta, I can't contribute there. I hope this workaround helps those who have this problem.

[CJ777]

Thanks for your contribution, however this doesn't work for Intel HD 2000. I gave it a shot anyway and though I would give my input. TF2 works fine on Windows with the HD 2000. Can someone explain how changing files to do with Steam will effect TF2?

[Teisei]

Hi! I'm not sure if HD 2000 is (yet) supported by Steam for Linux. But I sure hope it will, if it works on Windows.

EDIT: Also, if you launch TF2, does the in-game chat-overlay-thingy work?

[CJ777]

Yeah that's what I expected, yes the Steam-Overlay works, occasionally the Overlay will "overwrite" the textures, in games like World of Goo. This even happens after your "fix". Killing Floor works flawlessly though.

[Teisei]

That's strange. Maybe it's game specific after all ...

[iamoverrated]

Didn't help me :*(
I'm using a Radeon 5850

[AnAkkk]

It doesn't work for me either.

That's what its spitting out.

Okay everyone. This is a problem with locales obviously. I'd guess it has to do with different number-formats in different regions. Like the decimal point being a comma outside English speaking countries.

That said, you can set this behavior as the threadstarter said. You can also just run the game like this:

LC_NUMERIC=POSIX steam steam://rungameid/520

My question now: Where do we report bugs? Are the forums for reporting bugs or is there a bugtracker where we can report them?

[AnAkkk]

It's not only locale related. It could be that you are running the game on an unsupported intel video card.

[Schrödinger's cat]

I tried to launch TF2 with radeon open source drivers, but all I get is black screen with playing music. In terminal I get this: radeon: The kernel rejected CS, see dmesg for more information. Any solution for this?

Yes. They call functions this way: doSomething(float x, float y, ...). Now you can probably see the problem, they read the decimal point from somewhere (probably to create correct output for messages like errors or documentation). If its point then the function call looks like doSomething(3.14, 2.7) which is correct. If its comma the call is doSomething(3,14, 2,7), as you can see now they call 4 parameters instead of 2 and that causes errors.

That's actually a pretty dumb bug. I've already seen something like this in a CAD lib...

[CJ777]

I take it if the HD 2000 is unsupported they're not even going to bother fixing this bug? Looks like I'll be keeping a Windows install after all. :/ Will this bug happen with every Source game? The HD 2000 is good enough to play TF2, CS:S, and GMod so I don't know why they don't fix it.

You can't. That's the point of the limited beta. Only those 1000 people can report bugs. Don't worry, they have found this one already.
