Can't write to the /proc/acpi/ directoryas root.

Netromancer · 05-15-2004, 01:29 AM

Trying to get ACPI configured on a laptop running Mandrake 10. The permissions are set...

drwxr-xr-x 10 root root 0 May 14 23:57 acpi/

Can anyone point me in the right direction? TIA

Create files in that directory you are not supposed to, as far as I understand the 'proc' filesystem. 'proc' fs is to let you read messages from the kernel and to send commands to the kernel with those virtual files (they don't phisicaly exist in your HD).

But for a guru to help you here, you need to provide some more info. What are you trying to write in that dir ?

Also there is some documentation at : http://www.linuxforum.com/linux-acpi.php

[edit] Had wrong URL pointing to specification of acpi implementation >.<

Thanks for the url, I'll check it out.

The KDE power applet is telling me that I need to make the /proc/acpi/sleep file writeable but there is no such file. I was trying to create it.

If there is no such file that means that you probably need a new kernel with apic support.

Hmm. I think I compiled without APIC cuz this machine has to be booted with 'no local APIC for uniprocessors' anyway. Thanks, I'll check the .config file.
