Puppy Linux Discussion Forum

When adjusting screen brightness i prefer to adjust the backlight if possible, rather than gamma.
But not every system allows that and not every backlight goes as bright as i need on a sunny day.

So here is a brightness slider that works for me on most of my systems - it allows me to push the brightness beyond unity - in other words it pushes the screen into an "overbrightness" condition.

(Some systems do not report a "brightness" parameter within xrandr and will require a different script).

I usually only use it for short periods when a particular webpage is too dark or has poor contrast or i'm in bright light and my old eyes cant make out details on screen.

The original script was written by MochiMoppel to allow brightness control where the user has multiple monitors and all i initially did was to alter the "range" setting so that the slider can be pushed beyond "1.00"

As far as i know there was no original thread so consider this "not officially supported". Of course i will help answer any questions if i can...

Click on the script and push the slider as high or as low as you want.
Returning the slider to 1.00 resets the brightness to the original setting.

The slider appears at the location of the mouse pointer when the script is run.

When the slider is displayed you can make it disappear by clicking on it once, then clicking into whitespace. Remove .gz suffix and make executable

Changelog:
v0.1 and 0.2 would not run on some systems incl Fatdog
v0.3 worked better but did not read current brightness correctly
v0.4 Working well but code & comments untidy
v0.5 Tidied script comments & consulted MM re code to accommodate lowercase screen names. (Thx!)

Hi. This doesn't work on my acer chromebook 714 running fatdog64-810. Neither does it close.

Hi stemsee, thanks for the report.

Ordinarily i only run puppys but i just booted Fatdog 810 and have exactly the same problem you describe.

Unfortunately i don't have an answer for Fatdog at this stage. I will report back if I can work out why this happens.
(Maybe something to do with GTK version perhaps? Not sure yet)

cheers!

Me? Can't remember but checked the archive.

Hmm..must have been me:

Note that this version triggered bug reports. A few posts down I posted a fixed version. Claims stopped, so may work now.

Hi MochiMoppel,

thank you for the pointer to the modified version of the original code. I had not seen that.

Replaced original version in first post with a new version of overbrite based on that update. Not tested yet on Fatdog but i will give that a go later tonight.

Many thanks!


EDIT : Just tested on Fatdog64-810 and it worked perfectly. Than you Mochi for bringing that updated code to my attention.

greengeek,

It is best if you just edit the first post.
Put the overbrite v0.2 attachment there.

Keep the first post, always having the latest version.

Also, for the attachment overbrite v0.2
Does this still apply?
Remove fake .gz suffix and make executable.

It closes ok now, but nothing else ...zip...nada!

Done

Yes, it's a fake .gz suffix.

Does your xrandr output list brightness or Brightness as a parameter for your active monitor? I have noticed that some Puppies do not show that parameter.

I think there was an issue on some combinations of hardware/O.S - particularly 64bit - that was causing a problem in identifying the correct connected monitor.

If you don't mind i wonder if you would be able to try v0.3 and see if this runs ok?

cheers!

EDIT : Attachment removed as it still had an issue with reading current brightness value. Please try v0.4 in first post if poss.
thx!

I think v 0.4 has solved the earlier problems and seems to work well on all of the hardware/puppy combinations i have tested today (incl Fatdog64-810).

Uploaded to first post.

Output of my laptop's xrandr command.

Latest version is working !

Thanks a lot, greengeek; works on this Latitude E6410 laptop, BusterPup 32-bit.

Thank s. Puppy no offer much for the eyes
