Ben: From what I can tell, Linux perf is not capable of using separate
debug symbols to the running binaries like gdb can. It needs you to be
running the debug binaries, so the above wiki instructions won't work
for 'perf'. According to the Ubuntu convention I believe this means we
need -dbg packages built for unity and compiz. The -dbgsym packages
won't work with 'perf'.
All: If you did not do so already it is worth doing this before perf record:
sudo sh -c 'echo 0 > /proc/sys/kernel/kptr_restrict'
That should be the same as running "sudo perf record ..." but without
the need for "sudo".
