Launch steam and game with Steam Runtime enabled.
If its not by default, launch this

env STEAM_RUNTIME=1 steam

UPDATE:
i just tried to run the game without primusrun and started nornally...so it must be a problem with optirun(and primusrun)...any ideas now?

Hey guys. I had the same issue and could resolve it via following command (Steam must already be started):

$ cd "$HOME/.steam/steam/SteamApps/common/Left 4 Dead 2 Beta"
$ vblank_mode=0 PRIMUS_SYNC=1 STEAM_RUNTIME=1 primusrun ./hl2_linux -game left4dead2_beta -steam

Works for me like a charm! Thanks for the hint LostParadise.

[SUSEd]

Thats what i found on Reddit

right click on the game, properties and click on set lunch options and paste this
LD_PRELOAD=left4dead2/bin/matchmaking.so primusrun %command%
It seems to be a good temporary solution.

For me running with optirun fixed it.

I don't use primusrun and I get this issue on L4D2 (Beta) on Linux.

[Backofenpommes]

I had the same problem with primusrun and found a solution based on the stuff i read before:

Before that, i just startet l4d2 with an own script (not out of Steam, but Steam had to be started already), containing this lines:
---------
cd "~/.steam/steam/SteamApps/common/Left 4 Dead 2"
vblank_mode=0 PRIMUS_SYNC=1 primusrun ./hl2_linux -game left4dead2 -steam
---------


But to start it out of steam, use this solution:
Go to your L4D2-Steam-folder, and edit the hl2.sh with a texteditor.
Change the line (nearly at the bottom)
---------
${GAME_DEBUGGER} "${GAMEROOT}"/${GAMEEXE} "$@"
---------
to
---------
vblank_mode=0 PRIMUS_SYNC=1 LD_PRELOAD="$LD_PRELOAD:left4dead2/bin/matchmaking.so" primusrun ${GAME_DEBUGGER} "${GAMEROOT}"/${GAMEEXE} "$@"
---------

Then you don't have to edit any launch options. I also had the problem, that the ingameoverlay of steam were not accesible, but this is also solved by the changes above. Notice that LD_PRELOAD contains already a library for the overlay, and is overwritten, if you just give LD_PRELOAD a new Value. Therefore you must use _PRELOAD="$LD_PRELOAD:/path/to/new/library".

I would try something like i wrote above, but just use this line instead (cutting out primusrun-stuff):
LD_PRELOAD="$LD_PRELOAD:left4dead2/bin/matchmaking.so" ${GAME_DEBUGGER} "${GAMEROOT}"/${GAMEEXE} "$@"


BTW: if you don't know, where your L4D2-directory is, do this:
change the launch-options of L4D2 to

echo "%command%" > ~/l4d2path.txt

Then start the game via steam (nothing should happen), and clear the launch-options again.
You should now have a file named l4d2path.txt in your home-directory, containing the path of your L4D2-directory.

I hope i could help some desperate people.
