Bug ID: 503048
Summary: Nvidia: disable sleep when power management is not
setup correctly
Classification: Plasma
Product: plasmashell
Version: master
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Power management & brightness
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: 1.0
Nvidia needs a special setup to make suspend / hibernate work, see e.g.:
https://wiki.archlinux.org/title/NVIDIA/Tips_and_tricks#Preserve_video_memory_after_suspend
https://download.nvidia.com/XFree86/Linux-x86_64/565.77/README/powermanagement.html
Most distributions don't set this up for the user, resulting in a broken
out-of-the-box experience when returning from sleep. You can find a lot of user
complaints about this online.
As a safety measure, Plasma could disable sleep completely, when it detects a
Nvidia card as the main GPU and the needed services:
- nvidia-suspend.service
- nvidia-hibernate.service
- nvidia-resume.service
are not active and
/proc/driver/nvidia/params
is missing "PreserveVideoMemoryAllocations" and "TemporaryFilePath".
