Bug ID: 522329
Summary: High single core CPU usage desktop lagging when waking
up from sleep
Classification: Plasma
Product: plasmashell
Version First 6.7.1
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Power management & brightness
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: 1.0
DESCRIPTION
Upon waking up my laptop from sleep (s2idle), I noticed that the desktop
becomes really choppy for some a while and when looked at btop, I noticed
`org_kde_powerdevil` consumes 100% of a single CPU core.
I inspected the system journal and I have noticed that powerdevil is trying to
watch for some udev event changes? (dw_watch_display_connections). The
choppiness of the desktop could be due to it trying to access something from
the NVIDIA driver and not liking that.
I will attach a log of just what powerdevil has been spamming in the journal.
STEPS TO REPRODUCE
1. Put laptop to sleep
2. Wake laptop from sleep
3. Notice (at lest in my case) the desktop frame skipping
EXPECTED RESULT
System should run smoothly
SOFTWARE/OS VERSIONS
Operating System (available in the Info Center app, or by running `kinfo` in a
terminal window): Arch Linux
KDE Plasma Version: 6.7.1
KDE Frameworks Version: 6.27.0
Qt Version: 6.11.1
ADDITIONAL INFORMATION
Laptop has the iGPU disabled, running solely on the NVIDIA card as primary.
It has kind of been getting on my nerves as sometimes I gotta wake my laptop to
do something really quick on it and put it back to sleep, the whole desktop
starts having lag spikes along with the cursor itself and it's really annoying
that this point.
