Bug Description
This is likely similar to Bug #295251, but seeing that that one is supposedly fixed, I'll open a new bug report.
The brightness control on this laptop does not work (Fn+Up / Down) and produces e008 / e009 scancodes.
Manually adding those through
sudo setkeycodes e008 225
sudo setkeycodes e009 224
triggers the appropriate action, but the release code is not generated. I thought this was fixed with an older
kernel release, at least according to bug #295251 ...
I am on Lucid, kernel 2.6.32-21-generic. Hardware is Samsung R525-EIkee.
uname -a
Linux hadburg 2.6.32-21-generic #32-Ubuntu SMP Fri Apr 16 08:09:38 UTC 2010 x86_64 GNU/Linux
Will attach further logs later.

Hi Stephan,
Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http:// cdimage. ubuntu. com/daily- live/current/ . If the issue remains, please run the following command from a Terminal (Applications- >Accessories- >Terminal) . It will automatically gather and attach updated debug information to this report.
apport-collect -p linux 585946
Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https:/ /wiki.ubuntu. com/KernelMainl ineBuilds . Once you've tested the upstream kernel, please remove the 'needs- upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs- upstream- testing' text. Please let us know your results.
Thanks in advance.
