Bug Description
Under Ubuntu 11.04 with kernel 2.6.38-11, closing the lid on this laptop would change the value in /proc/acpi/
Under Ubuntu 11.10 with kernel 3.0.0-12, closing the lid doesn't change the value, and thus the kernel doesn't notice when the lid gets closed. The screen does turn off though (and back on on lid open); but this is only the screen backlight.
TEST CASE:
- Install Ubuntu 11.10 on a Samsung QX410
- Close the lid when the system is running.
Expected result:
- As per default configuration, the system should suspend.
Actual result:
- System remains fully powered, only the screen backlight turns off.
I also ran fwts lid and it was unable to detect the lid close events (as the kernel sends nothing).
Note that this constitutes a regression as the problem was not present on kernel 2.6.38-11.
I'm willing to run any diagnostics required to further pinpoint this problem. I'll also try a mainline kernel when I get some time.
Thanks!

I went testing mainline kernels to see when this problem first surfaced. Here are my results:
3.0-rc1-oneiric is good, it reports when the lid is closed.
3.0-rc2-oneiric is bad, it always reports lid open regardless of actual state.
3.0.6-oneiric is also bad, so the problem persists throughout the 3.0 series.
3.1-rc9 which is the latest as of yesterday is also bad, always reporting lid open.
So the change causing this misbehavior seems to have been introduced in 3.0-rc2.
