Re: lighting problem on ASUS

Could you provide dmesg and other logs for times when it was good and for times when it was bad?
In any case, setting LCD brightness via laptop-mode-tools or a manually written bash script should solve the issue.

You could try adding "acpi_backlight=vendor" to your boot loader's kernel line.
