comment Setting up a 3 monitor display?
Yes, obviously at the time of writing this answer the most recent RandR version was 1.3. I haven't had hands-on experience with 1.4 yet.

comment Caching write changes on SSD to avoid HDD spin-up? ZFS, but (probably) not L2ARC
@MichaelKjörling - yes, indeed :) So, using ZFS on SSD guarantees that a rotten bit won't pass unseen?

comment Multiple Screens cause flickering (only when laptop is charging)
LCD should not flicker, regardless of the refresh rate. Try using OSD menu of the monitor and adjust the clock sync rate (or similar option).

comment How to get started writing drivers?
OK, I have misunderstood you. Anyway, as the IDEAPAD_LAPTOP kernel module is responsible for such things in SL series of Thinkpads, you can start from looking at its source code. Also, you may be interested in some reading, for example on kernelnewbies: kernelnewbies.org/KernelHacking or a great book written by LKH: kroah.com/lkn Two other good sources that come to my mind are: lwn.net/Kernel/LDD3 and amazon.com/dp/0596005652/?tag=stackoverfl08-20

comment The simplest method to count lines matching specific patterns, including '0' if line is not found?
It almost works, with one exception - awk '{print($1 - 1" "$2)}' prints only the first word of matched line (second field, $2). If a line has multiple words, how can I write its whole contents, that is from $2 to end of line?
