Testing For The Latest Linux Kernel Power Regression
Frame-buffer compression (FBC) support was disabled by default in the Linux 3.15 stable series for Haswell hardware and newer since the support wasn't mature and there were Intel HD Graphics users reporting issues with this feature being turned on, so it was disabled by default and hidden behind a kernel module parameter. After an Arch Linux user experienced a 4+ Watt increase in power draw for his Apple laptop, he bisected it to this FBC feature, but Intel Linux developers weren't expecting FBC to make such a huge difference in power draw. The matter is still being investigated but FBC simply can't be flipped back on by default since the code is incomplete and there's still some unmerged patches under review that won't make it until at least the Linux 3.18 kernel.

Resistance to the Linux Desktop Is Futile – Get Over It
You see, I was out in the world for more than a decade teaching in many different communities all over Canada. At first it was rare to meet anyone who had ever heard of GNU/Linux. After a few years, about 2004, if I recall correctly, I began to visit random communities where one or more people actually had used GNU/Linux. These were communities from about 1K to 4K people in Manitoba, Saskatchewan, Alberta, Northwest Territories and Nunavut, so one person in 1K is tiny but definitely far beyond, “many average computer users have no idea that they exist”. I can promise you that all of the high school and many of the younger students in those communities did learn about it so the proportion abruptly changed to about 1 in 10.
