I'm trying to change the brightness steps in XFCE from 10 to 20. I'd like the ability to gradually change the laptop's brightness by 5% instead of 10%. Is there a way to set this up with a config file for XFCE?
If that is not an option, I have thought of another way: I know that I can disable XFCE's power settings from handling brightness keys, but setting up a shortcut in keyboard preferences does not seem to be able to override this.
Is there another way I can remap what XF86MonBrightnessUp
and XF86MonBrightnessDown
do when pressed? Specifically, I'd like Up
to use the command lumeus +5%
and Down
to use the command lumeus -5%
.
Can either idea be done while using XFCE with its XFWM?

No need to recompile the
xfce4-power-manager
There really is no need to recompile
xfce4-power-manager
.Firstly, install
xbacklight
Secondly, check whether you have control over the backlight.
Should these commands result in a
No outputs have backlight property
error, then follow these remediating steps before proceeding.Once
xbacklight -1
andxbacklight +1
work from the command line, proceed with assigning these commands to respectively theXF86MonBrightnessDown
andXF86MonBrightnessUp
keys. This is done by hitting those keys when asked by the Settings → Keyboard → Application Shortcuts application.Finally, reboot for these changes to take effect.
