Precise on a new 2012 NP900X4C (Ivy Bridge), same issues. Confirming #6 as well, lid switch detection worked briefly after a firmware update, but has since stopped working. cat /proc/acpi/button/lid/LID0/state shows that it's always open, no matter the physical state.
Also confirming #10, that the machine does not resume on opening the lid (and didn't even when the lid detection was working properly). Obviously it's likely an issue in ACPI, so I will look through the DSDT and see if any OSI changes have an effect. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/986724 Title: Lid state changes not detected on Samsung NP900X3B To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/986724/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
