From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030703 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 default) Version-Release number of selected component (if applicable): How reproducible: Always 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 display) Actual Results: Nothing happens Expected Results: Ideally, it should work just like it does with acpi=off Additional info:
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 better...
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.
