Original GitHub issue: https://github.com/netblue30/firejail/issues/997

When I have one isntance of steam running normaly on my computer with CSGO (Counter-Strike: Global Offensive) running, I am able to open another instance of steam using "firejail steam" in terminal but when I go to launch another instance of CSGO, it gives me the error "Only one instance of the game can be running at one time" in a window titled "Source - Warning"

I am on manjaro and have tried running "firejail --private steam" to see if that would work but I get the error "Coulnd't set up Steam data - please contact technical support"

Does anyone know a fix for this? Am I doing something wrong. I would assume this applies to all source games, not just CSGO.

Only one instance of the game can be running at one time

Some games, also main browsers like firefox and chrome always impose a single instance active in the system.

You have to delete /tmp/*.lock to run another CSGO!
You have to repeat it after any start of a CSGO instance on Linux.
But actually I am not able to run more than 5 at one PC.
