This would be an issue with Shatter rather than Steam, and would be better directed at their game support.

Not sure about that I have also Shatter version from Humble Bundle and it doesn't have such issues.

I am having a problem with Shatter too, the Humble Bundle version worked fine for me, now I installed the Steam version and, when the game starts, a black screen appears with this text:

I get stuck on this and can´t start the game.

Here are my specs: https://gist.github.com/Lord-Avallon/4521727

OK, if you launch STEAM_RUNTIME=0 steam and then load the game, this doesn’t appear?

Well, a message appeared: "You are missing the following 32-bit libraries, and Steam may not run: libSDL2-2.0.so.0".

Do you have SDL 2.0 installed?

Well, judging by the message, no, I think it´s another version, do you know the exactly name of this package? I looked on Google and on Synaptic but couldn´t find it.

Hi, do you know how to install this SDL 2.0 package? I couldn´t find the right name.

This is the content of the log.txt file:

Please, could you clarify something to me skybon (or someone else who can)? Where do I find SDL 2.0? I looked everywhere on the Internet and all I find are tutorials about SDL 1.2, even the official site http://www.libsdl.org/ doesn´t have 2.0 for me to download, the Ubuntu oficial repositories don´t have them too, where can I find it and how can I install it?

SDL2 is available either in
Mir PPA (patched for Mir support)
https://launchpad.net/~mir-team/+archive/staging

or Saucy repos:
https://launchpad.net/ubuntu/saucy/+package/libsdl2-2.0-0

I installed libsdl2-2.0-0_2.0.0~20130103-1_amd64.deb from the Saucy repo link skybon game me (by the way, thank you very much) and launched with STEAM_RUNTIME=0 steam, Steam didn´t initialize and the terminal output was:

Yet another game on Steam that requires "LC_ALL=C %command%" in it's launch properties to work properly on machines with non EN_us locale. No additional libs are needed, although it demands some when being run from a terminal.

After the last update the game doesn´t run, I click on the launcher button to start the game and nothing happens, even the dark screen I showed above doesn´t appear anymore (the word syncing blink on the side of the game´s name).

Now I have a NVidia GTX 650, but there is no way I can make this game run, one thing I know for sure, this is not video related, but after the last update even the black screen doesn´t appear anymore.

I tested the stand alone game again with my new video card and it works perfect, with all effects and everything set to high, this is a Steam issue for sure.

I'm having this problem as well.

@martinjakl did you ever resolve the "signal 11" error? I just purchased shatter on Steam and get the same thing when I try to launch.

I've just opened a separate issue for this crash : https://github.com/ValveSoftware/steam-for-linux/issues/2683

After the last update everything is working perfectly for me, thank you very much!
