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
