A simple trick to manage your LCD brightness by using command line:
echo -n 100 > /proc/acpi/video/VGA/LCD/brightness
This will make you LCD screen as bright as possible and you can proceed with your work (like me 
). To lower brightness just replace 100 with another value like 54 and watch the results
