[Touch-packages] [Bug 1872327] Re: OLED brightness control on Intel Iris Plus Graphics G7

2020-04-13 Thread Daniel Blatter
I found a workaround using a script that is triggered by inotify.

I created the script called brightness in /usr/local/bin:

sudo nano /usr/local/bin/brightness

content:
--
#!/bin/sh

path=/sys/class/backlight/intel_backlight

luminance() {
read -r level < "$path"/actual_brightness
printf %.10f\\n "$((100 * level/max))e-2"
}

read -r max < "$path"/max_brightness
xrandr --output eDP-1 --brightness "$(luminance)"

inotifywait -me modify --format '' "$path"/actual_brightness | while read FILE
do 
echo $(luminance)
xrandr --output eDP-1 --brightness "$(luminance)"
done
--

chmod 755 /usr/local/bin/brightness

Remarks:
- The script waits for change in 
/sys/class/backlight/intel_backlight/actual_brightness.
- "intel_backlight" might be replaced the corresponding directory name in  
/sys/class/backlight according to your installation.
- eDP-1 may be replaced by the display name (might be eDP1 or different). Check 
the correct display name using the xrandr command. 

Add the script to the in the system setting to be executed at login.

  Hi

  Adjusting the display brightness editing the file brightness in

  /etc/default/grub I already added "acpi_backlight=vendor"

Title:
  Backlight brightness control on Intel Iris Plus Graphics G7 on 20.4
  beta

Status in xorg package in Ubuntu:
  New

Bug description:
  Hi

  I'm testing kubuntu 20.4 with my HP spectre x360 13 aw0720nz.
  The hotkeys to adjust the backlight brightness do not work.
  It's no bug in KDE, as adjusting the brightness editing the file brightness 
in /sys/class/backlight/intel_backlight doesn't work either.
  At /etc/default/grub I already added "acpi_backlight=vendor"

  Regards Daniel
