Comment 37 for bug 89860

I see that the bug has been triaged. I also suffer from the bug. I'm running an up-to-date Gutsy install (uname -r = 2.6.22-14-generic).

cat /proc/acpi/button/lid/C20C/state always returns "open". Closing lid to standby works in vista, so it's not hardware failure.

Unfortunately, dmesg doesn't give any clues. I run dmesg, then close the lid, then open, and nothing new has appeared.

If I can provide more information or run some test please let me know.
