I own an Asus FX553VD which comes with a nVidia Geforce 1050 notebook and an integrated Intel graphics (on Kabylake 7700HQ). I installed Ubuntu 17.04, 17.10 and now Kubuntu 17.10. My problem is notebook works fine but I cannot reboot it. Sometimes after issuing reboot command or from menu it freezes and sometimes it just shows a blank screen then I should hold power button to power off system. Also I cannot run any tty session using ctrl+alt+f(n) keys since system freezes also. In Ubuntu everything was much worse, even freezing when I run a cpu heavy program. I can install nvidia driver but it consumes more power which drains battery and makes fans noisy as well. I even tried to install other distros like Antegos 17.11 but no success (Not even booting). Any ideas what can I do to solve the issue?
P.S. Also keyboard backlight cannot be changed.
