victor gasper: 1) Could you please post the missing information from a bad boot following https://wiki.ubuntu.com/DebuggingKernelBoot ?
2) To clarify, when booting up and using GRUB to boot into an older kernel, would this return to the previous behavior? 3) Regarding the suggested four kernel parameters, are you advising you tested each one individually (not in combination) and it had no affect? ** Summary changed: - Black screen at startup on Carrizo + [HP Pavilion 14-av005la (ENERGY STAR)] Black screen at startup ** Tags added: bios-outdated-f.26 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu.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/1642078 Title: [HP Pavilion 14-av005la (ENERGY STAR)] Black screen at startup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1642078/+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
