Tested Ubuntu 20.04 (kernel 5.4.0-52-generic) with the old HP Pavilion dv6 laptop and the bug seems to still exist.
Disabling the Plymouth boot screen fixes this bug (changing GRUB_CMDLINE_LINUX_DEFAULT from "quiet splash" to "quiet" in /etc/default/grub). Also closing and opening the laptop lid after boot turns the display back on. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1481442 Title: [HP Pavilion dv6-6145eo Entertainment Notebook PC] Laptop monitor turns off during boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1481442/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
