It's a confirmed bug, but not confirmed that it is a kernel bug. This could potentially be a buggy BIOS.
Please check if there are any BIOS updates for the machine(s) affected. Also check if there is perhaps an updated DSDT from the acpi website. ** Changed in: linux-source-2.6.17 (Ubuntu) Status: Confirmed => Unconfirmed -- On ASUS M6R, laptop lid is always reported as closed https://launchpad.net/bugs/66477 -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
