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?

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
