thinkpad sleep suspend fn buttons do not work without g-p-m

[Ryan]

Binary package hint: acpi

xUbuntu daily-live 3-2 used as install media, updated to 3-3.
Thinkpad R50

When I attempt to use the FN+F4 (Suspend to RAM) or FN+F12 (Hibernate) buttons on my thinkpad, the device does not suspend to RAM or disk. In /var/log/acpid I can see the button events & scripts being called in /etc/acpi/, but nothing happens. If I install & start gnome-power-manager, I can use the suspend to ram/disk keys successfully. Note that the machine can successfully suspend to ram/disk by using the XFCE Quit ~> Suspend/Hibernate function without gnome-power-manager.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with latest Ubuntu release? Thanks in advance.

This issue still exists as described in initial report. I have an up to date hardy installed from 8.04 x86 ISO.

Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here. Thanks for taking the time to make Ubuntu better!

This is the same as bug #281284 except this bug is for Gnome desktop

Confirmed. This is a bug in /etc/acpi/events/ibm-sleepbtn, which is configured to invoke /etc/acpi/sleepbtn.sh instead of /etc/acpi/sleep.sh: the former calls acpi_fakekey, the latter is what will trigger a sleep event when g-p-m is not listening.

This issue still exists in Xubuntu 11.10 (fresh clean install on Thinkpad T400).
