I have an issue with some Hotkeys working fine and some other (they physically do work I know). The keybind exist in my .confif/openbox/lxde-rc.xml file and for example the screenprint works fine. I want to set the brightness and it doesn't work, same for the volume... I've checked that xbacklight, xrandr, lxhotkey... are installed.
The only way to manage brightness is with the terminal xrandr --output eDP1 --brightness 1.3

</keybind>
<keybind key="XF86AudioMute">

Any ideas?
