I have recently installed Ubuntu 10.10 on my Dell Inspiron n5010 but screen brightness is not working, there is no effect of pressing fn+brightness keys.

Is there anyway to fix it?

I have exactly the same laptop with 10.10 netbook installed and have no issues - you do not need to use the FN key just press the brightness keys (5th and 6th key on top row) –  Mark Rooney Nov 28 '10 at 10:38
    
Thanks everyone. I just updated the BIOS and now brightness is working great. –  MA1 Jan 27 '11 at 13:49

How did you do it? Did you do so on Ubuntu? –  Oxwivi Jun 4 '11 at 12:04
    
@Oxwivi: Updated the BIOS from Windows, but you can do the update also from Linux. –  MA1 Jun 17 '11 at 19:58

You may have to choose Dell Inspiron as your keyboard layout in the keyboard section of Administration. I had to do this with my Fujitsu Seimens Lappy.

Maybe this laptop has the same problem as my Acer Aspire 4736Z.

Such shortcuts are handled by the udev subsystem. The configuration files exist in /lib/udev/.

The way it works is that you add a description of your laptop in /lib/udev/keymaps, and then activate it for your laptop in /lib/udev/rules.d/. There is more to the description I provide. You would need to read how similar laptop variants are handled already to get your laptop supported.
