Same problem here on Vaio VGN-SR after update to Lucid Lynx.
Brightness does not change with Fn keys and Power management properties.
When doing "sudo echo 52 > /proc/acpi/video/VGA/LCD/brightness" I've got a
permission denied error with "ls -al" giving

I forgot to mention that the graphic card is an ATI Radeon HD 3400 and I
installed proprietary drivers. I don't know if it could be the source of
problems.

@Chris Jepsen, I can't add as proposed by silvan, since I don't have an HP but

Actually problem seems to come from linux-image-extra
I had not the problem with linux-image-3.13.0-36-generic
But since I was missing some drivers I added linux-image-extra-3.13.0-36-generic
Then I had the problems again
I remove kernel-fixed-upstream then. Where can I find linux-image-extra for
I have found actually all drivers are included in mainline kernels. Then I
tested mainline kernels to find out last kernel without bug.
Last kernel from mainline without bug is 3.11.10
Kernels I have tested that have bug :
3.12.0
3.12.30
3.13.11
3.14.21
So problem comes from the very beginning
