Reboot cause screen brightness to reset and make screen blinking
Last modified: 2017-06-08 04:26:28 EDT
Description of problem:
When Fedora enters GDM login screen, brightness is reset to default level and screen blinks to black for ~5s and then works normally. But when I start to type password before screen turns black and go back to normal, I very often catch a screen freeze and must reboot whole computer.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot OS to GDM
Screen brightness is reset to default (to bright...) level. Screen turns black for ~5s.
Screen brightness is remembered from last session and screen doesn't turn black.
My notebook is Lenovo Yoga 3 Pro. I'm running Fedora 26 (Gnome with Wayland session) with all latest updates. I don't know if it's connected with kernel.
