Original GitHub issue: https://github.com/netblue30/firejail/issues/992

I am unable to launch certain games (e.g. Mount and Blade: Warband) when using the steam profile provided with firejail, or even when using --noprofile option. I am using firejail version 0.9.45. OS is Arch Linux with kernel 4.9.

Output in terminal when running firejail --noprofile steam:

CHIDDeviceListSDL(): Couldn't load libSDL2-2.0.so.0, not enumerating devices

Here's the output when the game is launched:

Ok so after a bit more investigation, I've noticed I see the same "CHIDDeviceListSDL()" error when starting steam without firejail, but I do not see the segfault from SDLHotPlugALSA.. that only shows up when using firejail. The game does run without firejail despite the earlier CHIDDeviceListSDL" error.

Also worth noting that I am using Pulseaudio 9.0, and have added “enable-memfd = yes” in /etc/pulse/daemon.conf (and restarted pulseaudio). I thought maybe the "hotplug ALSA" might be a hint in some way, from the segfault..

Something is going on with Steam. After an update last week on my Ubuntu 16.04, it doesn't work anymore, even without firejail. Or maybe is because of a Ubuntu update - hard to tell. Anyway, here are some other people running into problems: https://github.com/netblue30/firejail/issues/975

Question about Pulseaudio 0.9 - does it work with other programs, like "firejail firefox" or "firejail vlc"?

Hmm, Steam loads for me, and I can even launch some games (e.g. Crusader Kings 2), and play them just fine. Based on the segfault, it looks like it might be related to SDL, but I have no idea how to go about debugging it. I don't seem to be experiencing any of the problems in #975, but I am also using Arch Linux (first comment in that issue says Arch doesn't seem to be affected)

I've tested with the steam runtime and without it (using OS lib32-* libs in multilib Arch Linux), and have also tested with a new steam install (removed ~/.local/share/Steam and ~/.steam), the game still segfaults with the SDL Alsa error

Question about Pulseaudio 0.9 - does it work with other programs, like "firejail firefox" or "firejail vlc"?

Yea, it works fine with qutebrowser, firefox, and clementine, all through firejail.

Is there a way to determine which files this application is trying to access (presumably by running it without firejail), or run firejail in some sort of permissive-but-logging mode to see what it would normally deny so I can whitelist it? I've had no luck at all getting this application to run under firejail.

If you run "firejail --trace program-name" will print on the screen the files the program tries to access.

Thank you, I tried it.

So when I try to run the game, through Steam, I get (exactly) this in the console where I launch Steam:

Hmm, did something change that might address this? Because it's still an issue for me.

As a workaround, you can try to set the following launch options (right-click on the library entry for the game -> properties -> general -> set launch options) for the game:

unset LD_LIBRARY_PATH; %command%

This works for some games which give the ERROR: ld.so: object '/home/user/.local/share/Steam/ubuntu12_32/gameoverlayrenderer.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored. error message.

@chiraag-nataraj well, not sure since I gave up trying to run steam games through firejail.. now I just use system permissions (e.g. a dedicated 'steam' user) to 'jail' steam + games.

some games spread their tentacles far and wide and are also becoming a more popular target to attack

@SkewedZeppelin Running games under a local user with no access (using normal unix-y permissions) to anything else in the filesystem, etc should be sufficient without having to get into the container mess. All of the examples in that link are essentially non-issues with this method, since the user cannot access things owned by other users/groups it is not a member of.
