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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1169409 Title: [HP Pavilion 23] Brightness control doesn't work.
