I would suggest looking at how shm is mounted in your distro and whether users are given access. On my Gentoo machine I have this in fstab: shm /dev/shm tmpfs nodev,nosuid,noexec 0 0 For me, using udev, it gets the job done. NOTE: This also might be a groups issue. If your distro has an 'audio' group, for instance, and if your securities setup enforces a user being part of that group to use /dev/shm then this might stop you from being able to creat /dev/shm/jack-1000 when you try to run Jack as a normal user.
