I recently installed linux mint 13, mate desktop, on another partition, because the release notes for this Ubuntu derivative distribution mentioned that this release supported intel-RC6 at the "deepest" level. This was for Linux kernel 3.2 and Intel X driver 2.17.x. Enabling Intel-RC6 at this level makes an enormous difference in extending battery life and restoring nominal thermal characteristics. Without this, on the PCBSD9-20120505 snapshot, battery life is cut in half - at best - and the thermal envelope is so far removed from nominal that I would expect reduced CPU life as a result; fans always on, system is hot to the touch. With RC-6 enabled on lnux mint 13, battery life is about the same as when using win7, also installed on this laptop; about 5 hours+. CPU temperature varies between 39 C and 43 C; the system is cool to the touch and the fans never run; all nominal. In a previous post by Konstantin Belousov@, prior to the commit of Intel GPU driver to HEAD, it was noted that enabling RC6 produced artifacts. What is the state of Intel-RC6 support in the driver committed to HEAD?
