I'm no longer experiencing this problem. It's because of one of two reasons.
1. The problem may have been fixed. 2. Since my reinstall, I'm not using an application that was causing a conflict. - I'm using gnome-power-manager, nm-applet, and openbox with the xrandr fix. -- screen brightness oscillates slowly https://bugs.launchpad.net/bugs/258920 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-power-manager in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
