I really need help. I have Kubuntu 16.10 on my laptop a everything worked. With external hdmi monitor too. But once I unplugged the monitor, then plugged it in again. And now it doesn't work without the external monitor. After login I have only black screen. Any ideas?

  • Fn keys didn't work, so I modified /etc/default/grub (http://askubuntu.com/a/603980/619498) and now it works :) Muaad ElSharif: thanks for the hint :) – Jiří Dědic Nov 16 '16 at 11:21

To fix the keys not changing the brightness level, modify the file /etc/default/grub as mentioned here in Ask Ubuntu: Brightness fn key shortcut doesn't work on ASUS laptop
