Hi - I have a number of openSuSE 15.3 x64 that periodically experience bad sluggishness in responding to keyboard or mouse input. This can get frustrating with delays up to a minute or so after clicking on a button, or typing in a window. This occurs across all applications/windows open on a KDE desktop. Ksysguard aka System Monitor, nor top, do not show my why these slowdowns occur. I monitor CPU %, I/O Reads/Writes, Network activity and don't see anything indicating abnormal consumption of time. So given the fact that I am NOT a guru on Linux systems, what else can I do to try and track down (and hopefully fix or find a solution to) what is going on with my computers. What strategy(s) should I follow and what other tools might be helpful? Thanks for any advice/help in advance....

Every once in a while I encounter slowdowns as you describe, with Ksysguard showing the cpu being hammered (despite 8 cores) yet the process list does not show that. I don't know for sure, but I strongly suspect it is related to Plasma. Plasma can be restarted on-the-fly but I forget the syntax so I just quickly log out/in and that corrects it. HTH, --dg 15.3/Plasma
