My laptop freezes about every day, and I am using REISUB to recover. I tend to have Firefox open with a few tabs, maybe Youtube for music, Foxit PDF, Libre Office Writer, Spyder for Python, file browser, Clementine music player.
Ubuntu is up to date through sudo apt-get update (and upgrade) and the Software Update app. I have all Ubuntu Software sources from internet enabled (except source code - do I want that?).
I am a novice. Are there any simple and straightforward troubleshooting steps I can take?
