How to get perf fully working with all features?

Regarding:

Cannot load tips.txt file, please install perf!

I had the same issue on Ubuntu 18.04. TL;DR the error message is benign.

The tips.txt file comes from: https://github.com/torvalds/linux/commits/master/tools/perf/Documentation/tips.txt

As described in the original commit the purpose of this file is to show a random usage tip on the help line.

So if you wanted to get rid of the message, copy the appropriate tips.txt to /usr/share/doc/perf-tip/tips.txt.
