Just wanted to ask a quick question to see if anyone else has tackled this annoying issue. I installed Ubuntu 8.04 server on an old laptop to use as a sort of dev web server. In the laptop BIOS I turned off all power management to avoid it shutting down or hibernating at any point. After a certain point, the screen will go into 'sleep' mode so far as there is no longer text output to the screen, but the LCD backlight remains on. I am trying to get it to turn off the backlight as well so that it prolongs the life of the LCD along with consuming less power.<br>
<br>Just to note, I also tried enabling power management in the BIOS to turn off the LCD only after a specified time, but keep the system running. That had the same behavior. I know that with a GUI, the power management settings work as they should with the backlight turning off. This is an old laptop, so prolonging the life of the LCD is semi-important. I don't want to have to install fluxbox or some other GUI just to get power management to work properly, but if I must in the end, then I must I suppose.<br>
