Bug ID: 465559
Summary: ksystemstats turns on disabled nvidia graphics card
(possibly, other hardware)
Classification: Plasma
Product: plasma-systemmonitor
Version: 5.24.7
Platform: Kubuntu
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: ksysguard-b...@kde.org
Reporter: dvs-1...@yandex.ru
CC: ahiems...@heimr.nl, plasma-b...@kde.org
Target Milestone: ---
SUMMARY
plasma-systemmonitor or ksystemstats turns on disabled nvidia graphics card
(possibly, other hardware) when launches
STEPS TO REPRODUCE
1. If nvidia card is disabled (prime-select intel), when plasma-systemmonitor
(or ksystemstats from terminal) launches, it turns on nvidia graphics card with
optimus support (NVIDIA Corporation GP107M [GeForce GTX 1050 Ti Mobile]). In
normal state, the power is off on this device. You can close
plasma-systemmonitor or terminate ksystemstats (ctrl+c), but power state does
not change.
2. If lspci or kinfocenter->devices->pci launched, the card turns off and this
is normal behavior. Relaunch of lspci or kinfocenter->devices->pci does not
behave like plasma-systemmonitor, so plasma-systemmonitor is the main suspect
3. If you launch plasma-systemmonitor or ksystemstats (getting wrong power
state), close it or terminate ksystemstats (wrong power state remains) and
launch again, the power state gets normal
OBSERVED RESULT
The device gets stuck in wrong power state
EXPECTED RESULT
Plasma-systemmonitor acts like kinfocenter: hardware is probed, but does not
remain turned on if not needed
