View Full Version : [ubuntu] Upgrade from 16.04 to 18.04 problems with boot

November 30th, 2018, 06:58 PM
Hi everyone, I recently upgraded to 18.04 using the standard prompt from the operating system. On the first reboot i get stuck with this error at me:

13.0518761 rc.local[1236]: /etc/rc.local: 14: /etc/rc.local: cannot create /sys/class/backlight/intel_backlight/brightness: Directory nonexistent

I do remember the brightness button was bugging out recently, like when i turn it down it flicks the screen on and off. The screen also blinks at me constantly before settling on this message.

I can Ctrl-Alt-F2 into something that lets me log in into a non-gui interface but dont know what to do there really.

Any ideas please?

Thanks, Will
