Stats for display backlight being reported as 0mW
Hello
I was wondering what do I need do, so that powertop will properly read stats for my laptop's (lenovo e531) display. In case it's relevant, my GPU is a hybrid intel HD 4000/nvidia 740m one. I've already tried with both.
Currently this is how it looks like: 19.9%;Display backlight; 0 mW
I already tried setting the kernel's option acpi_backlight=vendor, but it made no difference.
These is how my current relevant kernel's config flags looks like:
$ cat /lib/modules/$(uname -r)/build/.config | grep CONFIG_NO_HZ
CONFIG_NO_HZ_COMMON=y
CONFIG_NO_HZ_IDLE=y
# CONFIG_NO_HZ_FULL is not set
CONFIG_NO_HZ=y
$ cat /lib/modules/$(uname -r)/build/.config | grep CONFIG_HIGH_RES_TIMERS
CONFIG_HIGH_RES_TIMERS=y
$ cat /lib/modules/$(uname -r)/build/.config | grep CONFIG_HPET_TIMER
CONFIG_HPET_TIMER=y
$ cat /lib/modules/$(uname -r)/build/.config | grep CONFIG_CPU_FREQ_GOV_ONDEMAND
CONFIG_CPU_FREQ_GOV_ONDEMAND=y
$ cat /lib/modules/$(uname -r)/build/.config | grep CONFIG_USB_SUSPEND
$ cat /lib/modules/$(uname -r)/build/.config | grep CONFIG_SND_AC97_POWER_SAVE
CONFIG_SND_AC97_POWER_SAVE=y
CONFIG_SND_AC97_POWER_SAVE_DEFAULT=0
$ cat /lib/modules/$(uname -r)/build/.config | grep CONFIG_TIMER_STATS
$ cat /lib/modules/$(uname -r)/build/.config | grep CONFIG_PERF_EVENTS
CONFIG_PERF_EVENTS=y
CONFIG_PERF_EVENTS_INTEL_UNCORE=y
CONFIG_PERF_EVENTS_INTEL_RAPL=m
CONFIG_PERF_EVENTS_INTEL_CSTATE=m
# CONFIG_PERF_EVENTS_AMD_POWER is not set
$ cat /lib/modules/$(uname -r)/build/.config | grep CONFIG_EVENT_POWER_TRACING_DEPRECATED
$ cat /lib/modules/$(uname -r)/build/.config | grep CONFIG_X86_MSR
CONFIG_X86_MSR=m
$ cat /lib/modules/$(uname -r)/build/.config | grep ACPI_PROCFS_POWER
# CONFIG_ACPI_PROCFS_POWER is not set
$ cat /lib/modules/$(uname -r)/build/.config | grep CONFIG_DEBUG_FS
CONFIG_DEBUG_FS=y

Hi @marcelopm, thanks for reporting the issue. I'm currently trying to reproduce the issue and will post a fix.
in part, powertop needs measurements of the screen on and screen off situation; without that it cannot do a model fit on estimate the power....

@marcelopm, please follow @fenrus75's suggestion and run a few screen off and screen on tests and then check the power estimate
@gkammela sorry, what do you mean by "run a few screen off and screen on tests" ? I tried closing my laptop's screen lid, waiting a few seconds and reopening it and repeated the process a few times while running powertop, but it doesn't seem to change anything.
@marcelopm, please use these commands below for screen off and screen on xset -d 0.0 dpms force off xset -d 0.0 dpms force on
@gkammela I can make the display to go off by using:
xset -display :0 dpms force off
However, as I hit key on my keyboard, the display goes on automatically.
I did that a few times and, just after the display goes on, I can see that powertop stated 0%, which makes sense. But then it just goes back to where it was before:
0 mW 29.9% Display backlight
