Graphics
From Linux 3.2 onwards, the DRM/KMS driver for Intel GPUs will enable
the very efficient and Intel-specific RC6 graphics power-saving
feature by default (1, 2). That change also enabled the Intel-specific
technique on Intel's current "Sandy Bridge" by default; unfortunately,
soon after the changes were made further problems were found with the
"Sandy Bridge" implementation and the kernel developers have disabled
"Sandy Bridge" support by default (1, 2) again. Since RC6 lowers the
power consumption of many Sandy Bridge systems with Intel graphics by
a few watts, it is especially interesting for notebooks as it can
significantly extend the battery life. It can be activated on older
kernels with the boot parameter i915.i915_enable_rc6=1, but those
versions lack fixes for some problems surrounding the use of RC6,
which have been included in Linux 3.2.
The Nouveau driver now uses the acceleration functions that are
available with the auto-generated firmware on the Fermi graphic cores
NVC1 (GeForce GT 415M, 420, 420M, 425M, 430, 435M, 525M, 530, 540M,
550M and 555, as well as Quadro 600 and 1000M), NVC8 (GeForce GTX 560
Ti OEM, 570, 580 and 590 as well as Quadro 3000M, 4000M and 5010M) and
NVCF (GeForce GTX 550 Ti and 560M) chips; Linux 3.2 will be the first
kernel version to support the latter graphics chips.} \unquote
