Yes. Settings > Power > Automatic brightness = On is the problem. If that's Off it won't happen anymore. For whatever reason the scaling of automatic brightness is wonky, and it might be that every model with a sensor reports a totally different scale, and isn't calibrated in any way. On my system it'll even go to the last setting and turn the display off as the room gets dark. It works better On than Off for daytime cloud fluctuations. But as the day transitions into night, the reduction in screen brightness is too aggressive. -- Chris Murphy -- test mailing list test@lists.fedoraproject.org To unsubscribe: http://lists.fedoraproject.org/admin/lists/test@lists.fedoraproject.org
