Description of problem:
I realize this is a known limitation of acpi in 2.4 kernels (isn't it?), but I
thought I'd report it for the record. Unless I boot my laptop with acpi=off,
the keys used to suspend to memory or to disk, to power-off the display, and
show the battery status don't work.
Given these limitations in acpi, perhaps it would be a good idea to add such
laptops to an acpi gray-list (i.e., acpi is not broken, but is not enabled by
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Boot Dell Inspiron 8000 without acpi=off
2.Press Fn ESC (suspend to memory), Fn a (suspend to disk), Fn d (power off the
Actual Results: Nothing happens
Expected Results: Ideally, it should work just like it does with acpi=off
It's not possible to have both ACPI and APM. This is something that just
is not a bug, and is a natural consequence of things like sleeping just
not working in 2.4 ACPI.
Because of the limitations of 2.4 ACPI, it looks like defaulting to
acpi being off, and being able to turn it on where necessary, will work
Agreed. It is not a bug, but it is a problem. Not being able to blank the
screen when it's not in use means shorter life for the LCD display. If only it
would blank properly after some period of time. But it doesn't, it goes black
but it keeps glowing. But that's a different bug.
Since ACPI is disabled by default, this is no longer an issue.
