When I'm using Ubuntu 11.04 on the same computer as my Windows 7, it shows videos a little darker than usual. I have a Dell laptop. The problem starts after about 10 to 15 minutes into the movie.

Actually now that you mention it i tried to check it with the power connected and it did not go dark on me. How to solve this then? – Phoenix3D Jul 16 '11 at 21:15
If it's not connected to the AC adapter, it's a power saving feature. – Uri Herrera Jul 17 '11 at 2:24
Go to system>power saving and adjust the settings to your liking. – Uri Herrera Jul 17 '11 at 3:15

Go to the Power Manager:

And Slide the Display bar to a higher value and/or uncheck Dim display when idle.

Vlc probably has a feature that keeps the display from being dimmed, doesn't it? Most other players do . I mention it cause it doesn't sound like a good idea to me to disable the dimming just for one application – Chriskin Jul 17 '11 at 3:40
I can't find anything in the VLC preferences . – Uri Herrera Jul 17 '11 at 3:53
Hye Uri thanks. Yes that solved it. That was the problem all along. – Phoenix3D Jul 17 '11 at 15:37
