Hello AceLan,
yes, I verified this issue again with 12.04.2+ update (3.5.0-45) and 12.04.3
(3.8.0-29) on 201206-11410.
Brightness control works with the proprietary driver nvidia-319
And another machine 201208-11466 is not affected.

Hi,
So, you mean the issue on machine 201206-11410 could be fixed by installing the
proprietary driver.
And another machine 201208-11466 is not affected.
Then, looks like we can close this bug?

Hello Acelan,
the system, HP Pavilion 23 (201206-11410), has only one acpi_video in
/sys/class/backlight.
With nouveau driver, the brightness cannot be adjusted, but it works
with the proprietary nVidia driver (version 319).
I will check HP Pavilion Sleekbook 14 (201208-11466) later.
Thanks.
