Hi, actually, on any recent distro with usable security settings for 
your
personal workstation you should be able to perf as your user.

That will avoid pain and make it a lot easier, e.g. hotspot should
be able to start it for you, too. I at least use it normally that way,
if I don't feed it myself into the flame graph scripts.
