I'm trying to get game controllers to work inside an unprivileged container, without exposing any more host details than necessary. This mostly works:
lxc.mount.entry = /dev/input dev/input none bind,optional,create=dir lxc.mount.entry = /dev/uinput dev/uinput none bind,optional,create=file lxc.mount.entry = /dev/hidraw0 dev/hidraw0 none bind,optional,create=file lxc.mount.entry = /dev/hidraw1 dev/hidraw1 none bind,optional,create=file lxc.mount.entry = /dev/hidraw2 dev/hidraw2 none bind,optional,create=file lxc.mount.entry = /dev/hidraw3 dev/hidraw3 none bind,optional,create=file However, a few games still do not detect the game controllers. I believe those games are looking for the udev device property ID_INPUT_JOYSTICK=1, which is missing in the container. (The host's udev lists dozens of properties for connected game controllers, while the container's udev lists only five.) Mounting the host's /run/udev in the container fixes the problematic games, but also exposes more host information than I would like, and breaks some apt-get upgrades until I retry them without the bind mount. Is there a better way to make game controllers' ID_INPUT_JOYSTICK=1 property visible in the container? While we're at it, is there a way to make joystick devices visible without mounting all of /dev/input/*, /dev/uinput, and /dev/hidraw? lxc: 3.0.4, host: ubuntu 19.10, guest: ubuntu 18.04. _______________________________________________ lxc-users mailing list lxc-users@lists.linuxcontainers.org http://lists.linuxcontainers.org/listinfo/lxc-users
