Comment 7 for bug 297962

As a next step I have modified the HAL keymap file:
/usr/share/hal/fdi/information/10freedesktop/30-keymap-misc.fdi

I've just added my laptop model:
> lshal | grep system.hardware.product
system.hardware.product = 'R510/P510' (string)

to the list of samsung models, making it:
<match key="/org/freedesktop/Hal/devices/computer:system.hardware.vendor" prefix_ncase="samsung">
  <match key="/org/freedesktop/Hal/devices/computer:system.hardware.product" contains_outof="NC10;SP55S;SQ45S70S;SX60P;SX30S;R59P/R60P/R61P;Q210;Q310;X05;R510/P510">

I have restarted HAL and now when I press one of the brightness combinations I see a notification with a screen icon and a bar in max position that can't be changed. The side effect of this is that the laptop keyboard got blocked now and I'm typing this from an external one. Still some things kept working like suspend (Fn+Esc) or keypad lock (Fn+F10).

Now, what would be a next step to diagnose the cause of the problem?
