Bug ID: 420148
Summary: CPU Usage illegible on systems with large numbers of
cores (e.g. Threadripper 3970x).
Product: plasmashell
Version: 5.18.3
Platform: Kubuntu Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: System Monitor
Assignee: notm...@gmail.com
Reporter: phelps...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
SUMMARY
The stock CPU usage tools such as System Monitor application and CPU load
monitor widget do not produce legible output on systems with large number of
cores. Attached is a screenshot for KSysGuard with on a 32 core / 64 thread
machine (Threadripper 3970x).
STEPS TO REPRODUCE
1. Install KUbuntu on a machine with a CPU with a high core count.
2. Run KSysGuard
3. Observe illegible display in 'System Load' tab
OBSERVED RESULT
EXPECTED RESULT
The display should be legible when the CPU has a large number of cores. For
example, there should be an option to show the total CPU usage as a single
graph rather than showing usage by individual core.
