Title:
Nvidia card consumes large amount of power in suspend mode
Status in linux package in Ubuntu:
Confirmed
Bug description:
I am running 19.04 on a Lenovo X1 Extreme. The laptop has an Nvidia
1050 Ti Mobile graphics card. I am using the Nvidia driver version 430
via the graphics-drivers PPA package nvidia-graphics-drivers-430 of
version "430.40-0ubuntu0~gpu19.04.2".
When the computer has the Nvidia drivers active via prime-select, a
large amount of power is consumed in suspend mode. I have attached the
output of this script:
https://www.thinkwiki.org/wiki/ACPI_sleep_power_drain_test_script
(battery-test.log) which estimates that the computer uses about 4.5 W
on average during suspend.
On the other hand, when the Nvidia card is not in use (prime-select is
used to switch to Intel graphics and bbswitch is used to ensure the
Nvidia card is off), the power drain during suspend mode is 1 W or
less. Therefore, it looks like the system fails to power-down the
Nvidia card before suspending when it is being used.
