how to disable acpi on command line


Thanks for similar. Bios is a good recommendation but will that affect the fan speed?
I know about the acpi=off option, this does not work properly- even on suse. Maybe noapic would work better? Really is there a cover all command line instruction (for all distros) to turn the annoying thing off? Main problem occurs when watching the telly and the screensaver kicks in, with suze it turns the sound off as well, even after you have re-entered the password.

Fred.

kernel-parameters.txt

At first, this sounds like an issue that might be attacked from a "disable the screensaver and any power management" angle. However, here's what turns up regarding acpi when I grep the 'kernel-parameters.txt' file on my 2.6.35 kernel - maybe something here will interest you, and if so, check out your own local version of this file in your kernel source, or Google it, to get the syntax & parameters of the option(s) which interest you:
Code:
root@reactor: grep acpi /usr/src/source/*/Doc*/kernel-parameters.txt | sed 's/^.*://'
