No problems, but you will know for sure after you have checked.

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

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?

Seems to be working well on examples, will need to check tommorow in production, as I am not sure if I have awk available there.

Uh, very weird. May be something with nvidia drivers - do you have nvidia-utils installed?
