Description jog 2012-02-09 18:05:55 UTC

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)

Comment 8 Zhang Rui 2012-02-20 06:16:29 UTC

can you please rebuild your kernel with CONFIG_ACPI_WMI cleared and check if the problem still exists?

Comment 9 Zhang Rui 2012-05-24 08:12:20 UTC

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.
