I can confirm this behavior on my Samsung Q45 (https://wiki.ubuntu.com/LaptopTestingTeam/SamsungQ45Dalia).
After boot closing the lid does nothing. After one Suspend-to-RAM and resume cycle, closing the lid works as expected. I'll attach the dmesg after boot and after the STR-resume cycle... ** Attachment added: "dmesg.after-boot.txt" http://launchpadlibrarian.net/13851957/dmesg.after-boot.txt -- /proc/acpi/button/lid/*/state always says "open" https://bugs.launchpad.net/bugs/89860 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
