Adding acpi_backlight=vendor to the kernel boot line allows the backlight to be changed on the Intel HD 3000 via xbacklight without root access. Perhaps a note could be added to provide this option. | Adding acpi_backlight=vendor to the kernel boot line allows the backlight to be changed on the Intel HD 3000 via xbacklight without root access.

Setting gamma and brightness
Intel offers no way to adjust these at the driver level. Luckily these can be set with xgamma and xrandr.
Adding acpi_backlight=vendor to the kernel boot line allows the backlight to be changed on the Intel HD 3000 via xbacklight without root access. Perhaps a note could be added to provide this option. papabean (talk) 02:40, 14 January 2013 (UTC)
Best performance options
In my experience (i5 CPU, Z77 chipset) the best performance can be had with the following options:
- SNA acceleration method
- Vertical sync enabled
- TearFree option enabled
-
i915.semaphores=1kernel option turned on
Using the ck kernel specific to the CPU architecture also seems to make the video performance more consistent, but not necessarily any faster.
