Thank you Peter for your suggestion of acpi_osi=Linux acpi_backlight=vendor. I added those to /etc/default/grub and ran update-grub2 and indeed the laptop now does not boot into a dark screen. It has been booting into a dark screen since 12.04, but I only found this tip after I have updated to 13.04. Still, it helps! -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1173059 Title: Ubuntu 13.04 boots to dark screen on HP G6 laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1173059/+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
