Missing /proc/acpi

[pwabrahams]

The battery status widget on my Oneiric system indicates no battery/no AC adapter, though both are present. Apparently the problem is that /proc/acpi is missing. Since I keep my system fully updated, what package am I missing?

Re: Missing /proc/acpi

To answer your question, Vinny:

pwa@pwa-K60IJ:~$ ls /proc/acpi
ls: cannot access /proc/acpi: No such file or directory

If I'm running with the noacpi option set, where would I find that setting? I remember at one time having to fiddle with that stuff to solve a problem, but that was quite a while ago.

Re: Missing /proc/acpi

it would be on the end of your boot line in /boot/grub/grub.cfg

when I do a search for acpi in synaptic I find acpid,acpi-support,powermgmt-base & toshset
installed .

Acpi quandary

I found the acpi setting in /etc/default/grub: it's the line GRUB_CMDLINE_LINUX_DEFAULT. I had acpi=off there. I removed it and the battery indicator worked again -- but the brightness control no longer worked. The indicator moved correctly but the brightness didn't change.

So the quandary is this: with acpi enabled, the battery indicator works but the brightness control doesn't. With acpi disabled, the brightness control works but the battery indicator doesn't. Is there any way to get both?

My guess is that there's some kind of kernel bug here, but I don't know where to report it.

Re: Missing /proc/acpi

Other GRUB_CMDLINE_LINUX_DEFAULT options you can try are:

noapic
acpi=noirq
acpi.power_nocheck=1

Trying one at a time. It may be that none will give you the 'solution', but it won't hurt to try.
