Re: [gentoo-user] Re: Power management or something?
I have a fresh install of Gentoo on my laptop and I'm having some trouble with the backlight that I think is related to the screen going into some sort of power save mode or something along those lines. Are there power management settings somewhere or something similar? I'm on xfce4. - Grant >>> >>> I found another clue. It happens whenever I shut my laptop screen, >>> even for a moment.

I installed xfce4-power-manager thinking it would do the trick for sure, but unfortunately the behavior is the same even after messing with the settings. Weird - Grant

Now the screen just goes black when the lid is closed, saving some power, but nothing locks, sleeps, hibernates or any other such response. I did nothing in the kernel that I see. HTH, Mark

I think my solution was a KDE setting which won't help you unless there is something similar with XFCE. I'll boot the laptop and see if I Can spot what I did. Ah the things we have time for when watching Hulu on a Sunday morning... ;-) Back later, Mark
