I have a new Lenovo IdeaPad 720S with Nvidia graphic card. When I want to restart or shutdown Ubuntu, my laptop freezes and I have to manually shut it down.
I know about the method by changing the line in Grub:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" acpi=force apm=power_off
But when I did that, I could not change the display brightness. Neither by the keyboard physical bottoms nor through the setting/display brightness.
Any idea or suggestion how can I finally have Ubuntu 18.04 running on my laptop?
