Actually.. this is quite embarrassing, I installed 3.12, but my system didn't show a grub menu and I actually booted 3.13.0-24-generic
Not sure how that happened, but it actually appears that the issue has gone away somehow. Could still be a race maybe? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1309584 Title: [HP EliteBook Folio 9470m Notebook PC] Backlight does not work on intel driver after upgrade from 13.10 -> 14.04, acpi_backlight=vendor solves To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1309584/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
