[question]Pause/resume brightness adjusting, Set gamma to max/min gamma in a script ?

[promeneur]

The script I wrote using the statements you supplied to me in the past

---

#!/bin/bash

#Pause brightness adjusting
busctl --expect-reply=false --user call org.clight.clight /org/clight/clight org.clight.clight Pause "b" true

#Set gamma to max gamma
busctl --user set-property org.clight.clight /org/clight/clight/Conf/Gamma org.clight.clight.Conf.Gamma NightTemp "i" 6500

/usr/bin/cvlc

#Restore gamma to min gamma
busctl --user set-property org.clight.clight /org/clight/clight/Conf/Gamma org.clight.clight.Conf.Gamma NightTemp "i" 3500

#Resume brightness adjusting
busctl --expect-reply=false --user call org.clight.clight /org/clight/clight org.clight.clight Pause "b" false

---

It seems the statement has no more effect.

What are the good ones ?

Thanks

Hi!
Sorry for the late response!
That is weird; it should work! Can you share the clight.log while running the script?
Thank you!

Here is the log when launching then quitting VLC

It seems that messages changed. In the past, there were explicit messages as:

• gamma set to 6500
• gamma set to 3500
  etc.

I want the true colors (colors without any filter) when using VLC or Digikam.
When brightness management is suspended, is brightness really set to full brightness ?
When gamma management is suspended, is gamma really set to 6500 ?

I think this might be a new script:

# Pause brightness calibration
busctl --expect-reply=false --user set-property org.clight.clight /org/clight/clight/Conf/Backlight org.clight.clight.Conf.Backlight NoAutoCalib "b" true

# Set max backlight level
busctl --user --expect-reply=false call org.clight.clight /org/clight/clight org.clight.clight IncBl "d" 1.0

# Set gamma to max gamma
busctl --user set-property org.clight.clight /org/clight/clight/Conf/Gamma org.clight.clight.Conf.Gamma NightTemp "i" 6500

/usr/bin/cvlc

# Restore gamma to min gamma
busctl --user set-property org.clight.clight /org/clight/clight/Conf/Gamma org.clight.clight.Conf.Gamma NightTemp "i" 3500

# Force a backlight calibration
busctl --expect-reply=false --user call org.clight.clight /org/clight/clight org.clight.clight Capture "bb" false false

# Resume brightness calibration
busctl --expect-reply=false --user set-property org.clight.clight /org/clight/clight/Conf/Backlight org.clight.clight.Conf.Backlight NoAutoCalib "b" false

I cannot recall why i shared the script you shared :/

I tested with digikam the brightness adjusting (gamma adjusting is currently disabled). Here is the result when launching (10;27)and quitting (10:29) digikam.

---

(I)[10:15:48]{backlight.c:455} Ambient brightness: 0.809 (-0.017 screen compensation) -> Screen backlight pct: 0.933.
(I)[10:25:49]{backlight.c:455} Ambient brightness: 0.826 (-0.018 screen compensation) -> Screen backlight pct: 0.941.
(I)[10:27:22]{backlight.c:560} Backlight autocalibration disabled.
(I)[10:29:33]{backlight.c:455} Ambient brightness: 0.836 (-0.022 screen compensation) -> Screen backlight pct: 0.944.
(I)[10:29:33]{backlight.c:560} Backlight autocalibration enabled.

There is no message saying "brightness is set to max. Is it normal ?

[promeneur]

I made this test :

• I launch digikam
• i launc a video call with skype
• during videocall i quit digikam
  ambient brightness adjusting is not restarting immediately

Is brightness set to max indeed?
Is this working?

ambient brightness adjusting is not restarting immediately

This is ok, because during a video call brightness adjusting is not working since camera is busy.

I checked there si no more problem.
