Title: Flickering display brightness when maxing out brightness Status in linux package in Ubuntu: New Bug description: Affected version Your OS and version: Ubuntu 19.10 Affected GNOME Shell version: 3.34.2 Does this issue appear in XOrg and/or Wayland: Haven't tried on Wayland. Bug summary When the slider for the brightness is dragged to the far right (maxed out), there seems to be flickering a few seconds later. The delay time somewhat varies, sometimes 5 seconds later, sometimes 30 seconds later. When a power source is plugged-in, the flickering seems to stop, then the flickering continues. When the power source is removed, the flickering also stops, then continues later again. Steps to reproduce Power-on computer. Max out brightness slider. What happened Display brightness is flickering. What did you expect to happen Display brightness should not flicker.
