gerjantd, if closing the lid does not change the state of /proc/acpi/button/lid/LID/state, then you definitely have either a kernel bug or a hardware bug (and probably a kernel bug, from what you've said). Reassigning this report to the kernel package.
Users with different symptoms than those described by gerjantd should file separate bug reports for their issues. ** Changed in: linux (Ubuntu) Sourcepackagename: acpi-support => linux -- No blank screen when laptop lid is closed https://bugs.launchpad.net/bugs/293063 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
