I konfiguracja Xorg:

    Screen 0 "nvidia"
    Inactive "intel"
EndSection

Section "Device"
    Identifier "intel"
    Driver "modesetting"

    Option "AccelMethod" "None"
EndSection

Section "Screen"
    Identifier "intel"
    Device "intel"

Section "Device"
    Identifier "nvidia"
    Driver "nvidia"
    BusID "PCI:1@0:0:0"
    Option "ConstrainCursor" "off"
EndSection

Section "Screen"
    Identifier "nvidia"
    Device "nvidia"
    Option "AllowEmptyInitialConfiguration" "on"
    Option "IgnoreDisplayDevices" "CRT"
EndSection

Ale widzę dużo łez od chromu, filmów itp.

Dowolny pomysł?

Nie pamiętam linku, z którego otrzymałem te ustawienia. Mam również Intel i7-6700, ale mam trochę nowszą wersję GTX970M. Po wielu próbach i błędach te ustawienia działały dla mnie (z komentarzem starych ustawień):

$ cat /etc/X11/xorg.conf.d/20-nvidia.conf
Section "Device"
    Identifier "nvidia"
    Driver     "nvidia"
