L4D2 with Bumblebee or Nvidia Optimus (save room crash)
Try this please:

0) Start Steam without(!) optirun or primusrun

1) Go to L4D2 folder: "Steam/SteamApps/common/Left 4 Dead 2 Beta/"

2) Enter this: "vblank_mode=0 primusrun ./hl2_linux -game left4dead2_beta -steam"

I could play campaingns without crash at each save room. You too?

This solution works. But if you have problem:
Failed to load the launcher (libSDL2-2.0.so.0: cannot open shared object file: No such file or directory)
You need to locate where is the library libSDL2-2.0.so.0 and preload it.
In my case:
LD_PRELOAD=~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/libSDL2-2.0.so.0 vblank_mode=0 primusrun ./hl2_linux -game left4dead2 -steam

I think u should also use STEAM_RUNTIME=1 or add to LD_PRELOAD this .so.

Hi... thx for that solution...

One thing, in which file i has to write "vblank_mode=0 primusrun ./hl2_linux -game left4dead2_beta -steam"

thx

Hooray!
'Safe room crash' and 'libmatchmaking.so' bugs are fixed.
Now you can start game simply with 'optirun -b primus %command%'.
