Default I would like to understand how brightness works

Hello.
On a laptop where
$ xbacklight...
doesn't work, I tried
$ xrandr --output outputName --brightness brightnessValue
and it works.
Reading something I understood that xrandr produces only a software modification.
On the other hand, xbacklight (if working) would produce a hardware modification.
I observed something I'm not able to understand.
Out of X (console mode) I'm not able to modify brightness with
$ wsconsctl display.brightness=value (obsd 6.0).
Inside X (after startx) I'm able to modify brightness with xrandr and, if I exit X, modification persists also in console mode.

The questions are:
1) is it correct to think that X is able to do software modification that persists out of X?
2)Which kind of modification does "wsconsctl display.brightness=..." produce? Hw or sw?
3) can anyone suggest me something to read if I want to understand more deeply how
brightness works?
Thanks.
Have a good day.

Hi attilio,

I can confirm your observation regarding the xrandr command. I just tested it myself.

Let's have a closer look: if you re-read the manpage for xrandr(1) you'll see this:
Quote:
--brightness brightness

Multiply the gamma values on the crtc currently attached to the output to specified floating value. Useful for overly bright or overly dim outputs. However, this is a software only modification, if your hardware has support to actually change the brightness, you will probably prefer to use xbacklight.
Thus the xrandr command will only adjust the colour brightness. Sth like:
Code:
$ xrandr --output LVDS1 --brightness 80
turns my screen into a 1980es fashion style nuclear accident. Whereas
Code:
$ xrandr --output LVDS1 --brightness 0.5
"dims" the screen by totally reducing all colour brightness (sw) without actually changing the brightness of the screen's backlight (hw). On a macbook you can check this nicely by looking at the transparent logo on the rear of the lid.
As you observed, xrandr's colour brightness setting is persistent when switching over to the console. Even after killing the X server(!). This is not the case with xbacklight(1)

When you're in an xterm and just type xbacklight what do you see? If it's a number, that would indicate the current hardware brightness value in % and you should be able to modify it. But if you see a message like
Quote:
No outputs have backlight property
it may mean your machine doesn't support the hw brightness setting.

On my macbook both commands work, for instance:
Code:
xbacklight -set 80
or
Code:
wsconsctl display.brightness=20
However, when switching back to the console from X the wsconsctl(8) brightness value is reset to 100% (apparently this is a bug).

I believe manipulating xgamma(1) indirectly manipulates the screen's backlight in cases where you can't adjust it directly? I haven't tried this myself, but might be worth investigating. In FreeBSD I've used a wrapper called xbrightness which is in ports, but this has not been ported to OpenBSD.

Usually if the fn+[brightness up/down] keys work outside of the OS, for example at POST or in the BIOS/UEFI, then you have hw brightness setting. If not, then you have only software brightness setting, probably dependent on some windows software installed by the laptop vendor.

Hello fvgit and cynwulf.
Thank you for your answers.

On an old hp530 xbacklight works and also fn+F* works.
The effects of both don't persist when I exit X and I go in console mode.

On another laptop, hp 250 G(2,3,4? I don't remembre) xbacklight doesn't work and hardware control of brightness doesn't work too.
xbacklight doesn't say anything. No output.
I can check with "xbacklight -get" that the value of backlight changes, even if it changes strangely.
At the beginning it is 100%, then 0, then 1.280082. I don't understand the logic of these values.
Anyway no effect on the brightness.

I think that "software modification" (see xrandr's man page) means that all values of RGB components of a pixel (suppose from 0 to 255 for Red Green Blue) are multiplied times the float value you insert. So for a command like
$ xrandr --output nameOfOutput --brightness 0.8
maximum value of the RGB components will be 255*0.8=204.
Perhaps, after this command, if someone tries to paint 256 areas with 256 different values of, let's say, red, she would observe that they are not really all different (only 204 really different intensities mapped by 256 values: some overlapping).
Instead, probably, after a working xbacklight command, one still has 256 values and 256 really different intensities for every RGB component.
I will try.

Thank you again.
Ciao! (Italian greeting)

Just an update on this type of issue. I have a (cheap) Acer laptop where xbacklight responds normally (i.e. not the "no outputs have backlight property" message), but brightness goesn't change, e.g.

Code:
$ xbacklight
50.000000
$ xbacklight -set 100
$ xbacklight -set 50  
$ xbacklight -inc 10 
$ xbacklight          
60.000000
$
All responds as if it's working but does absolutely nothing. (My guess is a crappy ACPI may be the cause.)

xrandr's "--brightness" option:
Code:
xrandr --output LVDS1 --brightness 0.8
This is simply an adjustment of LCD colour "intensity", it won't change a thing with regards to the backlight (same with the gamma setting and xgamma). So this may seem to do the job in certain ambient light conditions, but won't do a thing for you in low light, e.g. where the backlight's fixed brighness can be uncomfortable.

The X server log file contains this line:
Code:
[    26.170] (--) intel(0): Found backlight control interface wscons (type 'platform') for output LVDS1
wsconsctl adjustment of "display.brightness" also has no effect even though (as with xbacklight) it appears to work.

Adding the line to /etc/wsconsctl.conf as also has no effect.
Code:
display.brightness=50
The Fn laptop keys + brightness up/down keys do nothing of course. It's likely they rely on some vendor specific MS Windows programme.
