    Desktop for 5 minutes slowed to a crawl

    Hello.

    Yesterday something weird had happened.

    Was developing in Android Studio, had Chrome and terminal opened in background.

    Then all of a sudden the system became unresponsive and I was not doing anything taxing at the time. Moving the mouse took about 15 seconds to even register the movement on the screen. Trying to get into VT1 was only greeted with black screen. Then after 5 minutes all was well again.
    But then after about half an hour later the same issue had re-appear.

    My question is what is the best way to debug what is going on here?


    My machine:
    Core I5 4690
    8 GB RAM
    Amd Radeon 7870XT Tahiti Core using proprietary driver, as the open source one would not even boot the PC.

    try leaving a terminal open running "top" and see if you can catch a process hogging CPU
