Hi all, I've installed lubuntu-desktop over Ubuntu 14.10. I'm ironing out some of the issues, but this one has me stumped. When I plug in the AC power, the display backlight dims considerably. I can't find a display brightness setting, but the keyboard brightness hotkeys work (they work both on battery and AC power). The display just makes a step-change downwards in brightness when plugged in....Thanks in advance!
