Grub menu - gray backlight (brightness same as grub menu background) - then a flash (white), not covering the whole screen - black( 0% brigthness, lasting 6 sec) - gray like before. cold start: grub-menu - gray - flash (white), not covering the whole screen -a cycle of 16 times: black and gray - the last gray note: runnig Ubuntu, brightness cannot be changed running Windows10, no brightness problem. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1639517 Title: [HP Pavilion Notebook - 17-g164ng] black screen when booting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1639517/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
