Ah, this is indeed what I meant by "standard". I believe that the
Sleep/Hibernate buttons in KDE, Gnome etc. use pm-hibernate et. al.
and that most desktop distros use pm-utils on a kernel without the
TuxOnIce patch. I actually thought TuxOnIce was obsolete until someone
mentioned it on the nixos irc channel.

I tried `hibernate --force` via the version 2.0 Hibernate script:
http://tuxonice.net/files/hibernate-script-2.0.tar.gz

I found the documentation on their site pretty sparse so I assumed I
should use that script as opposed to the pm-hibernate command (I will
try pm-hibernate on the TuxOnIce kernel later though, just in case)

After a few hibernation cycles, pm-hibernate fails to hibernate for me
so I thought I'd try out TuxOnIce. Previously, with Debian Lenny on
the same laptop, I had various issues related to pm-suspend. On resume
my external screen would blink, and after about a week Xorg memory
usage would increase to over 1GB and it would take over 30mins to
resume. Unfortunately, I can no longer use pm-suspend on NixOS as I
have a BIOS problem (it auto-reboots when I shut
down/hibernate/suspend ... also via Debian).

It would be interesting to hear if anyone is successfully using
TuxOnIce on nixos, the reason I call it's hibernation script with
"--force" is because it fails to find a list of blacklisted kernel
modules, which is something I may need to fix. I will inquire further
with the TuxOnIce folks and report back if I get anywhere.

Thanks a lot for all your help!
