Public bug reported:
Upon upgrading to the Intrepid alpha from Hardy, a significant amount of
ACPI functionality has failed on my Lenovo Thinkpad X300.
Event that still work (seen by acpi_listen):
- ac adapter / battery
- button/lid (although suspend is not triggered as expected on close)
- ibm/hotkey for lcd brightness (although brightness is not actually adjusted)
- ibm/hotkey for thinkvantage button
Events that no longer work:
- power button
- volume up/down hotkeys
- cannot wake up from suspend via any hotkeys/lid
I'd be happy to include any other desirable information to help diagnose
and fix the issue. The lack of events coming to acpid seems like a
kernel or thinkpad-acpi issue but the lack of suspend-on-close and
brightness adjustment seem to be userspace problems (acpi-support?).
Regards,
Jon Oberheide
