g'morning all... this morning i find that "display brightness is once again missing from the power management settings... any idea where it's been moved to? the default setting isn't bright enough for me to read, and leaves me with an even darker left half of the laptop screen... setting the old display brightness to 100% gave me a uniform glow from left to right...

I moved this to hardware issues spence, as I thought it might get a little more attention here. If this is unsuitable, let me know, and I will move it back. ;)

I've never seen that as part of the power management settings. However, I can set display brightness with my XServer settings, I don't know if you can on your machine. Dunno if that helps you or not.

If not, there's a program in the repository called ddcontrol that you might check out. Supposedly, you can control all of that with gnome-power-manager that comes installed, but I don't see it on there when I bring up the program.

Sorry Spence for the confusion, but this may have led to the (solved), and locking

It's unlocked again, and this should serve as a bump. :D

thanks oldrong... this morning when i 1st logged on the option to "set display brightness" was again missing from the bottom of the power management console... i rebooted peppermintOne and the setting reappeared...

what would make this mysteriously come and go of its own volition?

aside from gremlins...

I'm not sure, but it almost sounds like one of the mysterious upgrade bugs we have been getting from time to time. About all I can offer is the hope that some future bug fixes may correct it for you. I wonder why we haven't had some other folks jump on this post and make the "I have the same problem" statements we seem to always get. :lol:
Maybe Rich_Roast, Kendall, or one of the "smarter than me" mods will come around and help solve the issue. :D

spence , you may want to try poking around in /proc
On my system ATM , the file I'm talking about is /proc/acpi/video/VGA/LCD/brightness
if you open that up, the contents will be pretty straightforward as to what it does
If that's the right file for your set-up, you can try in terminal (as root)
Code:
echo -n 50 > /proc/acpi/video/VGA/LCD/brightness

That should set the brightness at well, 50
the row of numbers on the first line of the brightness file will tell you what values you can use in place of 50
you should then be able to change your display brightness all willy-nilly and stuff, without relying on the power manager that seems to be plagued with problems for you.

If the command works for you, and you want to get clever with it, a script using zenity or yad to call a GTK window for you to input the desired value and then pass it to change the file should be easy enough to do.
Or you can just set a couple of aliases using your preferred values to enter into terminal
Power Manager may override your change somewhere down the line,
I honestly don't know if it will or not
If it does, we may be able to figure out how to prevent it
