Expected: After updating via Muon (incl. the kernel, see above, I think), the computer should restart normally. Actual: After the HP logo, the computer displays a black screen, backlit. Nothing happens, completely unresponsive. Workaround: Temporary: Add "nomodeset" before "quiet splash" via editing of GRUB menu. See: https://askubuntu.com/questions/162075/my-computer-boots-to-a- black-screen-what-options-do-i-have-to-fix-it Permanent: Edit /etc/default/grub: the line "GRUB_CMDLINE_LINUX_DEFAULT=". Add the word "nomodeset" before "quiet splash". - Run "sudo update-grub" ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2068793 Title: Black screen on restart after update: fix "nomodeset" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2068793/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
