With 3.0 kernel, laptop no longer suspends on lid close. There are several bugreports on launchpad https://bugs.launchpad.net/ubuntu/+source/linux/+bug/874749 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/400097 Works perfectly on 2.6.38 Closing the lid simply dims the screen. acpi_listen does not trigger any event.

> Works perfectly on 2.6.38 set "Regression" flag What laptop is failing? What is the most recent kernel where it did work? What *does* happen on lid close -- any messages in dmesg? Please attach the output from acpidump please kill acpid and # cat /proc/acpi/event and show the output for lid close & open (if any) as well as the output from 'grep acpi /proc/interrupts' across this period and also the state in /proc/acpi/button/lid/*/state Also, please verify that your GUI is configured to suspend on lid close events.
This is on a System 76 pangolin 6 laptop. It works fine on 2.6.38 Screen just goes blank - nothing in dmesg (acpi_listen triggers nothing either) No output from # cat /proc/acpi/event - Nothing generated grep acpi /proc/interrupts shows 9: 184 46 IO-APIC-fasteoi acpi state in /proc/acpi/button/lid/*/state correctly states open and closed events cat /proc/acpi/button/lid/*/state state: open and cat /proc/acpi/button/lid/*/state state: closed GUI set up correctly. (In fact when I boot from 2.6.38 kernel, it suspends correctly)

can you please rebuild your kernel with CONFIG_ACPI_WMI cleared and check if the problem still exists?
bug closed as there is no response from the bug reporter. please feel free to reopen it if the problem still exists in the latest upstream kernel.
