How to dim the screen?

[toomuchcomputertime]

Is there a way to dim the screen on puppy? I often work in the dark and the screen is way to bright.

Thanks.

Turn the knob of the brightness lower.

Turn the knob of the brightness lower.

You beat me to it

Or if on a laptop usually a key combination does it usually the Fn key plus another your manual should tell you

If you have a newer puppy you can do this with xgamma,

Code: Select all

xgamma -rgamma 0.9 -bgamma 0.9 -ggamma 0.9

from commandline.

You can use every value between 1 and 0.1 to make it darker,
every value between 1 and 10 to make it brighter.
Obviously you can calibrate different colour channels.

There is even a standard gui for this, probably in Setup/xorgwizard/ Monitor Gamma calibration, but this is broken so you can get no darker values.

0 - + 100: brighter
0 - - 100: darker

Wow, Thanks everyone for the responses.
Beem and _Mark_, this laptop doesn't have a brightess knob, but it does have Fn keys that work - in Windows only.

Emil, Thanks I just tried your app, also the one from the menu worked (I'm using 5.2), however, it just darkened the colored parts of my screen, is there a way to dim the white parts? I tried the command line, and both scripts but they all did the same thing.

- I've been playing traitor and using Kubuntu for awhile and was enjoying the brightness adjustments there, and am using puppy again - its changed since 4.2.

KDE doesn't allow processor scaling right now, and puppy does it well, also runs faster even though it isn't 64bit, and doesn't burn my computer apart (43 C instead of 88 C)

Thanks

Have you checked out Fluppy? It is made for laptops. Most of my laptop's features work well with fluppy ootb

good, so its in!

I noticed, It's pretty suboptimal.
I think proper dimming involves also to lower the "backlight" property of your monitor. There is a X11 command-tool which should do this

http://boxen.math.washington.edu/home/e ... xbacklight

problem is that it has to work with your graphic drivers/chipset/videcard. I get
# ./xbacklight
No outputs have backlight property

So it doesn't work for me ...
Maybe, as already suggested, you could try Fluppy witch have best set of drivers for netbooks.

Thanks. I just tried your xbacklight and the xbacklight from Fluppy (I think it is)

But they didn't work. This is a toshiba which has had quite a few problems with drivers in the past. Thanks for the ideas everyone.

Well brightness knob = fnkey combination.
My laptop fnkey combination works independent of the OS fortunately.
If yours doesn't, I don't know if there is a solution.

Thanks everyone,

postfs1, I haven't tried your suggestion yet, but plan to when I get a chance.

I helped a friend by using a hardware fix. I purchase a roll of colored cellophane from a gift shop and doubled it and taped it to the screen. It worked for that him.
