[ubuntu] Screen Brightness Glitch

view full story

http://ubuntuforums.org – I have an MSI Wind U120 (I dont know if that's relevant) and when I use the shortcut keys to turn down or turn up the brightness it switches between two brightness levels right next to each other and makes my screen flash between brightnesses. This also happens when I shut my laptop screen and open it up. It DOES NOT flash between brightnesses when I use the brightness applet on the panel. I was wondering if there's any way to make this stop because it is really annoying. Please reply soon thanks in advance! (Hardware)
