Thanks Lars, I’m silly: I had not realized that the Fx keys in this 
laptop have to be toggled-on with the Fn key, and somehow concluded that 
the memstick installer supports only one terminal…

Nevertheless, I hope support for these laptops improve. I have not 
tested yet several suggestions found on the internet to enable LCD 
brightness adjustment or keyboard backlight, which with suspend/resume 
do not work out of the box, neither the Intel 7260 Wireless chip and for 
sure the Haswell GPU.

Unfortunately, I can only provide time for testing patches.

Best regards,
Juan
