Bodhi Laptop Backlight Slider doesn't work for me
Topic sums it up. The moksha gadget doesn't do anything, slide up, slide down, nothing changes.
It's a sony laptop (VPCF115FM) and fn+f5/fn+f6 also are supposed to adjust it, but they don't do anything under bodhi either. |
Here are some clues.
If I press FN+F5 a bunch of times,then reboot, my backlight is quite dim. Slider is still all the way up. [I must then FN+f6 a bunch of times then reboot to get bright again.] If I turn the slider all the way down, then reboot, my backlight is quite dim. Slider is back to the top tho. [I must then FN+f6 a bunch of times then reboot to get bright again.] Basically, my conclusion is that backlight changes don't take effect until after reboot, and the slider (moksha module) apparently can't read the current state (on my hardware). Obviously, my goal is immediate changes. |
Do the backlight buttons work in any other distro? I mean everything is working ok here, or as programmers are fond of saying it is working on my machine ;)

I hope you have learned how to use a terminal and some basic cli commands, if you are willing to looking your system file-system to be sure of correct paths/dir you can use this or at least check to see if your system is even willing to turn up your lights.

I booted puppy. There is no built in slider. However I did learn something useful when I searched how to set brightness in puppy. By changing /sys/class/backlight/acpi_video0/brightness it works. (I didn't think to check the F-keys) Back in my Bodhi installation, I see the slider is adjusting that the value in that file too. One difference is I'm using nvidia drivers under bodhi, whereas puppy was just live usb using noveau. So I booted Bodhi live usb. Slider works fine. So I think it's somehow nvidia driver related... |

make google your friend. look at https://wiki.archlinux.org/index.php/Backlight
in the nvidia part, towards the bottom of page and see if that does anything. |
Solved. Once I knew to search Nvidia related, I found a solution.
create /usr/share/X11/xorg.conf.d/10-nvidia-brightness.conf with the following: Code:

Good Job :) Glad you worked it out.
