I have an Asus K53SM laptop and it is running 16.04.1
The brightness would reset to maximum value on restart. So i messed up while was playing around with
sys/intel_brightness files acpi_video0
the etc/grub/GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
and rc.login entry acpi_video0 intel_brightness
The brightness issue after "suspend and re awake" did not get solved.
I have a black login now, I am not sure if it is low brightness or a broken login screen.
I have access to grub and ubuntu recovery mode.
I tried altering back the values using an Ubuntu CD but cannot change acpi_video0 value which is 10, my highest brightness value is 4882.
Please help me restore the settings and guide me through this.
Thanks
