My laptop is running Linux 2.4.23, built from pristine official sources. I've enabled ACPI and disabled APM in the kernel configuration (built into the kernel); if I boot the laptop normally, it behaves as expected, and I can poke around at things in /proc/acpi and check on things like the current draw on the battery and change the processor speed. (Expected battery lifetime increases by 66% if I change it from the fastest setting to the slowest.) Nothing happens if I close the lid (under APM it would suspend-to-RAM), but looking at the sourceforge site, this is expected and I'm just doomed on that front under a 2.4 kernel.
This all changes if I put the laptop into the dock, though. I generally get to work, dock the laptop, then boot it; this gets me a better display resolution when gdm starts. :-) But, ACPI is totally scrod now. /var/log/kern.log says: Dec 9 13:03:16 everett kernel: ACPI: Subsystem revision 20031002 Dec 9 13:03:16 everett kernel: PCI: PCI BIOS revision 2.10 entry at 0xfd906, la st bus=15 Dec 9 13:03:16 everett kernel: PCI: Using configuration type 1 Dec 9 13:03:16 everett kernel: ACPI: IRQ9 SCI: Level Trigger.

Is this mostly right? Is there a way around it? (And if it did work, would I be able to undock the laptop under Linux using a magic ACPI call? :-) -- David Maze [EMAIL PROTECTED] http://people.debian.org/~dmaze/ "Theoretical politics is interesting.
