Screen Brightness

I had no luck with a screen brightness step of 1, in acpi handler. Adding these clauses to handler.sh works better.

   video/brightnessdown)
       bl_dev=/sys/class/backlight/acpi_video0
       actual_bl=`cat $bl_dev/actual_brightness`
       # Lower brightness has no effect until it is lowered enough to change actual_brightness.
       # Brightness less than 10 causes problems when increasing!
       while [ $actual_bl -gt 10 -a $actual_bl == `cat $bl_dev/actual_brightness` ]
       do
           echo $((`cat $bl_dev/brightness` - 1)) > $bl_dev/brightness
       done
       ;;
   video/brightnessup)
       bl_dev=/sys/class/backlight/acpi_video0
       actual_bl=`cat $bl_dev/actual_brightness`
       # Change in brightness has no effect until it is changed enough to change actual_brightness.
       while [ $actual_bl -lt 100 -a $actual_bl == `cat $bl_dev/actual_brightness` ]
       do
           echo $((`cat $bl_dev/brightness` + 1)) > $bl_dev/brightness
       done
       ;;

This is a mess, it should be cleaned up before adding it to the article (e.g use $( ) instead of `, input redirection not cat, avoid [, etc). -- Alad (talk) 14:34, 4 June 2015 (UTC)

Hi! I think it can be useful if we put a banner on top of this page to warn users that logind already implements some acpid features. Eventually we can highlight which of these features are already implemented, and a link to the systemd wiki page. Nierro (talk) 17:40, 3 August 2013 (UTC)

The Power Management page (a section from systemd was recently moved there) links to this page correctly, but you are right - some note to read Power Management#Power management with systemd first would be useful. But I'd still keep the old examples using pm-suspend etc. until pm-utils is finally deprecated. -- Lahwaacz (talk) 17:51, 3 August 2013 (UTC)
The fact is that pm-utils, being no more a dep of upower, is really unlikely to be installed. While every user should have systemd and "systemctl suspend". So I find it better to use systemctl instead of pm. For the banner, i think it should be added. Nierro (talk) 18:29, 3 August 2013 (UTC)
It seems i'm jumping forward when upower 0.9.21 hit extra...i'm using testing so i didn't notice. By the way systemctl suspend is equivalent to pm-suspend, and i guess upower 0.9.21 will hit extra in a few days. Nierro (talk) 18:31, 3 August 2013 (UTC)
Alright, but this doesn't make much sense - why not use the logind mechanism you talked about? I'd delete that example too, there's already one example on button/lid close. -- Lahwaacz (talk) 18:51, 3 August 2013 (UTC)
Damn sorry, you're right obviously. I must be really tired. Thank you for pointing that out! Nierro (talk) 18:54, 3 August 2013 (UTC)
Is there more to discuss here? Other things I could think of is check if systemd-logind is running like Debian does [1], or perhaps mention systemd-inhibit. But I doubt either is worth documenting. -- Alad (talk) 14:30, 4 June 2015 (UTC)
