It would help answering if you provided a modicum of information. I believe your operating system is not Gnome, it is some Linux distribution. Which? What version? If you can access terminal, type command Code: lsb_release -a Next problem: which perf utility are you asking about? Perhaps provide a link to the description in your Linux distributions package description page? Writing a link in message is only allowed after 10 messages written in this forum, but leave the http:// part away and just write the URL replacing dots with space. https://forum.howtoforge.com/thread...or-a-first-time-linux-user.83782/#post-399369
