As a baseline, the 3.8 kernel works normally, with text displays on all six vts. Both the 3.9 and 3.10 kernel's fail in different ways and to different degrees.
3.9 - does not work first boot (poweroff or reboot) - works (if power drained, battery removed) - no console display (vts 1-6) - reboot via C+A+D still works 3.10 - no display at all, regardless Going back to 3.8 required full power drain (battery removal) and two reboots. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1247967 Title: nvidia optimus chipset disabled when running on battery, even in discrete mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1247967/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
