Marking as "fixed" for indicator-power since the brightness slider was removed for 14.04. ;)
mpt, are you seeing this behavior in system settings as well? If so you may want to add that package to this ticket. ** Changed in: indicator-power (Ubuntu) Status: Confirmed => Fix Released -- You received this bug notification because you are a member of DX Packages, which is subscribed to indicator-power in Ubuntu. https://bugs.launchpad.net/bugs/1289477 Title: Display brightness can lag far behind moving the slider Status in “indicator-power” package in Ubuntu: Fix Released Bug description: Ubuntu Trusty r188 1. Access any of the brightness sliders: in System Settings > "Brightness", or System Settings > "Battery", or the Battery menu (bug 1289470). 2. Rapidly slide the slider from minimum to maximum and back again, about ten times, then let go. 3. Wait. What happens: The phone repeatedly dims and brightens over several seconds after you stop touching the slider. What should happen: The current brightness level is always either on, or less than ~500 ms from reaching, the brightness shown by the slider *right now*. Any values that the slider was on previously should be ignored. Compare bug 1306499, the equivalent problem with the volume slider.
