Bug ID: 492440
Summary: Setting cap_sys_nice on KWin prevents System Monitor
app and widgets from being able to query its memory
usage
Classification: Frameworks and Libraries
Product: ksystemstats
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: General
Assignee: plasma-b...@kde.org
Reporter: n...@kde.org
CC: ahiems...@heimr.nl, vlad.zahorod...@kde.org,

Target Milestone: ---
KWin sets this when built from source and recommends that distros set it too;
see
https://community.kde.org/Distributions/Packaging_Recommendations#KWin_package_configuration.
However this prevents ksystemstats from querying its memory usage; open the
app, go to the processes page and search for "kwin", and you'll see that it has
its CPU usage reported, but not memory.
This is a somewhat significant omission as KWin is a core system component
especially in a Wayland session, so being able to monitor its memory usage is
important.
`top` is able to gather memory usage statistics for KWin in this state, so
ksystemstats ought to be able to do so as well.
