The screen-brightness keys on the Fujitsu-Siemens Esprimo Mobile U9210 works somewhat, resulting in a progress bar being shown, and the brightness level changing. However, the brightness-up key appears to produce both an brightness-up and a brightness-down event, with the result that it is only possible to decrease the screen brightness.
Following the step-by-step troubleshooting guide at https://wiki.ubuntu.com/Hotkeys/Troubleshooting resulted in the following:
2) Xev does not produce any keycodes for the two keys.
4) Using the udev keymap utility did not produce any events
6) Using acpi_listen, the following events resulted:
When pressing the brightness-down key:
video DD04 00000087 00000000
When pressing the brightness-up key:
video DD04 00000086 00000000
video DD04 00000087 00000000
