I recently installed Ubuntu 18.04.1 LTS, but I have some trouble where my PC is stuttering from time to time. The whole PC lags for about second and keeps on going. Wouldn't really be a problem, but it also happens when I play games, where it can be very annoying.

I would like to have some help, and type if you need any system information.

  • Welcome to Ask Ubuntu! Yes, of course, we need your system information in this type of question! Please edit your question to include your HW specification. You should also include the output of the free -h command, don’t forget to apply code formatting.

  • Thank you for the update. Your RAM (3.3GB) seems to be quite low, your swap gets almost exhausted moreover. While your machine still fits the minimal requirements, it can be pretty limiting for more demanding applications. What applications (including games) are you running on this machine?
