Binary package hint: gnome-power-manager
In Ubuntu 11.04 Natty on my ThinkPad T420, the power button is ignored even though gnome-power-manager is configured to ask what to do when the power button is pressed. Neither of syslog, kern.log and dmesg have relevant logs.
Hard shutdown by pressing the power button for a long time works, but this is a hardware feature.
I'm not sure how to further debug this issue.

Same on the T61 too. After dist upgrade, powerbutton doesn't work anymore.
