Foresight and hibernation

--


For some reason hibernation does not work when I click on
the flashy icon on the desktop in my current version of
Foresight Linux (version 0.9.8.2). I never really expected it
to work anyway, me being suspicious of all attempts by the
computer to make life easier for me. They normally just make
life harder... have you noticed this before as well?

Anyway. I tried it the trusty old fashioned way, by command
prompt as root, and voila! It worked. So I guess I'll be
filing a bug with the foresight people when I get the
chance. Oh and the trusty old fashioned way (in the kernel 2.6
series, with the /sys directory activated) is by doing this:
# check memory
free -m

# if you have more swap than memory, you're fine.
# if not, dont do the below

# become root
sudo bash

# disconnect all physical usb gadgets.
/some/rlly/wild/shllscrpt/whch/dscncts/yr/phys/usb/devs -a

# tell the system to hibernate
echo -n 'disk' > /sys/power/state


To restart, boot the laptop and wait for the prompt. Make
sure you choose the same boot option as last time, since
otherwise the wakeup wont work properly.

Afterwards, networking wont work. Just restart dhclient and
you'll be fine. Oh and dont forget to reconnect your usb
stuff. Should you forget to disconnect the USB devices in
advance, no panic. In earlier releases of the kernel the
hibernation just didnt work at all with USB devices connected,
but nowadays it seems to go into hibernation regardless. When
woken up, you'll just have to pull out your USB cables and
stick them back in again.

tada.
