Ubuntu Studio & Qsampler

[holotone at gmail.com]

My output shows exactly the same permissions:

holotone at iceman:~$ ls -l /dev | grep shm
drwxrwxrwt 2 root   root          40 2007-11-12 10:31 shm

Not sure I understand what strace is, and I'd hate to start executing
commands that I don't understand.

Thanks for your help!
