When i try to launch any game in steam it comes up with preparing to launch for e.g Dota 2 then that box closes and never loads game up.

Any help would be appreciated.

  • Just restart steam...!! It worked for me...!! – SY_13 Aug 24 '15 at 14:35

Try this:

  • Right click on TF2 in your library → Properties → Set Launch Options
  • If you only have optirun, enter: optirun %command%

The above did not work for me and I had to set the launch options as

LD_PRELOAD="libpthread.so.0 libGL.so.1" __GL_THREADED_OPTIMIZATIONS=1 optirun %command%

This occurred for me after backing up a game. It would show the 'Preparing to launch' dialog box then close it without launching. The solution for me was this:

  1. Make a backup of the game.
  2. 'Delete local content' for the game (in Right-click -> Delete local content)
  3. Restore the game from your previous backup.

I got the same problem with other games and could fix it by out commenting the lines

GAME_DEBUGGER="strace -f -o strace.log" LD_PRELOAD=../src/thirdparty/gperftools-2.0/.libs/libtcmalloc_debug.so:$LD_PRELOAD

in the launch script, hope this helps

    Can u explain what this comment does? I'm just curious...!! – SY_13 Aug 24 '15 at 14:32

Is your computer x64? For some reason some Steam games need the x86 library... This happened to me as well, and Steam Support told me to do the following:

  1. Open up Terminal

  2. Type the following command:

sudo apt-get install ia32-libs

You might need to put your login password because of the sudo command...

After you've done, it should work with any game. If it doesn't, you might need to enable de Dev. Branch of the game. So, to do so:

  1. Right click the game you want to play, and chose properties.

  2. Click in the Betas tab, and select Development Branch from the dropdown and then close the window.

  3. Try to open your game.

If this doesn't help, you might want to contact Steam Support. Gaming in Linux is in some point "new" and still has it's "problems" so they should help you though.
