    Power Management Screen not turning off.

    I have an issue where the screen on my laptop will not shut off with the power management tool. The Default Power Manager does not have an option for this.

    My screen will go blank after a set amount of time, but the lcd-backlight will remain on.

    I would want the power manager to shut the screen off completely (including turning off the lcd backlight) without shutting down the computer it-self. So the computer can continue to do what I left it to do in the case I forget to close the lid. With the screen shut off completely, it will preserve the life of the back light and reduce power consumption.

    Is there a better power manager app that will allow me to do this or a tweak to the existing default power manager that will allow the functionality I am seeking?

    My laptop was perfectly able to do this under a win-xp environment, so I know the machine is physically capable of doing this. Note: My WinXP OS and Ubuntu OS are on seperate physical drives so there is no dual boot issues. So when I am using one there is no trace of the other present.

    Thanks For Any Help You All can provide!

    Exact same issue here.

    I initially thought it was just an issue with the "When laptop lid is closed, do nothing" option, where closing the lid wouldn't turn the screen off.

    However, after testing just now, it appears that even setting "put display to sleep when inactive for: " doesn't work at all. My screen just doesn't turn off ever, for any reason, unless I shut down my laptop.

    Very irritating. I did find a bug related to this on the bug report forum, so maybe it's just broken currently.

    Mine seems to be working now at least partially.

    I set the screen-saver (which is blank) at 1 min and the display to sleep at 5 min. and it works only when i have unplugged the mouse.
    also had to check the "Activate Screen-saver when computer is idle" box.

    and after a restart it works like it is supposed to. The backlight and screen go off completely, BUT only if I have unpluged my mouse. I'm conducting more trials to see what may be going on.

    Hopefully someone here might have some more insight.

    Looks Like I'll have to mark this as solved. Although I do not know how it was solved. Maybe it was in one of the updates I get daily. My Laptop display powers off completely just like it should now, mouse or no mouse connected.
