wakeup via PS2K/PS2M not working, unable to toggle in /proc/acpi/wakeup

[wamanning]

so i'm running 9.10 for about a week now, after upgrading from 9.04 and 8.* prior. i'd like to enable the wakeup via my PS2K(eyboard) and PS2M(ouse).

running this @ terminal:


cat /proc/acpi/wakeup

returns this (color added by me for posting clarity):


Device S-state Status Sysfs node
...snip...
PS2K S3 disabled pnp:00:06
PS2M S3 disabled pnp:00:07
...snip...

which shows them as disabled. so i type this at the terminal to toggle their s-states (i.e., enable them):


sudo echo PS2K > /proc/acpi/wakeup
sudo echo PS2M > /proc/acpi/wakeup

then i re-check their s-states with this (same as before):


cat /proc/acpi/wakeup

and these 2 devices are still disabled.


Device S-state Status Sysfs node
...snip...
PS2K S3 disabled pnp:00:06
PS2M S3 disabled pnp:00:07
...snip...

i've googled the interwebs and searched these forums and i've found no information beyond what i've already learned and done here.

i'd appreciate any tips!

EDIT: what makes this strange is that i *AM* able to toggle the s-state of WOL using the exact same procedure:


WOL S4 enabled pci:0000:02:00.0

Reaching for straws here...
Do you have keyboard/mouse wakeup enabled in your pc's bios?

[wamanning]

i believe so, yes. wakeup from stand-by used to work for this workstation on prior releases of ubuntu as well as in windows.

i'll check again, though...i have had a bunch of changes to the system w/ hard-drive configs and whatnot, so it's worth a look.
