I'm having the same problem using Linux Mint 13 (based on Ubuntu 12.04) with a Compaq nc6000.
Lid state /proc/acpi/button/lid/C139/status is always set to "open", but if I hibernate (pm-hibernate) and wake-up, lid button works correctly. acpi_listen shows in both cases (with and without hibernating) the lid events: button/lid C139 00000080 00000048 The last number is increased in each event. In each event, /etc/acpi/lid.sh is called. This script checks /proc/acpi/button/lid/*/state and acts in consecuence. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/89860 Title: /proc/acpi/button/lid/*/state always says "open" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/89860/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
