The existing binds show a brightness bar going up and down but nothing happens, however the brightness applet on the bar does actually work.

Root cause: otter-osd called Brightness.enumerate() and used the first sysfs node (often acpi_video0). Bar applet matches eDP to intel_backlight/amdgpu_bl. enumerate() now selectBestPanel: eDP/LVDS symlink, then native names, never keyboard, acpi_video last. Restart otter-osd. Pushed otter-desktop a20ef40, otter-osd 2faa070.
