    Lubuntu 11.10 Brightness issue

    Hi All!

    I am running Lubuntu 11.10 and when my display turns off, the screen does not return to full brightness afterwards. It is only half brightness and I cannot get it to full again. The function keys are working but will not go any higher than halfway brightness.

    The problem is with xfce4-power-manager but I'm not sure what.

    I have not had this problem in debian+lxde or ubuntu 10.10+lxde.

    Anyone else have this issue? why wont xfce4-power-manager return my screen to full brightness anymore?

    Sorry but your problem is different that the Original Poster's Problem. He/She is using Lubuntu while you are using Ubuntu. Two different Desktop Environemnt.

    Please search the forum for a similar case to yours and if you couldn't find, try here: www.googlubuntu.com.
    If you couldn't find, start your own thread

    Thanks!

    So I disabled xfce4-power-manager at startup and it's still happening so it's not the power manager.

    Saw something about acpi somewhere?

    Saw an old suggestion here but it didn't work for me.

    You could try xbacklight to adjust the brightness.

    That did the trick! Your a savior! I can use my computer! Now if I could only figure out what's causing it..

    Edit: Ooh I am also totally binding this to a hot key.

    I've been experiencing this same dark screen issue on my eeePC 1005 HAB running Lubuntu 11.10. It actually only started happening recently - like a month ago.

    xbacklight has solved this for now.
