pm-suspend stuff

Howdy Guys,

I followed the wiki article for pm-suspend/hibernate, and my laptop seems to suspend fine when I do "sudo pm-suspend."

When I resume, though, usb is dead.   pm-suspend.log isn't much help.  There's a section in the wiki about bringing back mouse functions, but that solution does not work (maybe because the module name in the wiki is not the same as the one I'm using?)

anyway,  how do I get resume to include usb?

This Ubuntu user (don't worry, that's a great thread there despite the fact that it's Ubuntu) got it to work by adding ehci_hcd to /etc/default/acpi-support in the MODULES array there...not sure if this is the same on Arch (I'm not on my Arch machine atm, but I will check tomorrow since I am heading off to a Radiohead concert shortly )

Re: pm-suspend stuff

put that module in /etc/pm/config.d/unload_modules.
if isn't working create your own hook. see wiki or http://en.opensuse.org/Pm-utils

Re: pm-suspend stuff

Ok, in the file

/etc/pm/config.d/config

I have these lines:

UNLOAD_MODULES="uhci_hcd"
SUSPEND_MODULES="button usbhid ehci_hcd uhci_hcd"
RESUME_MODULES="uhci_hcd ehci_hcd usbhid"

I did pm-suspend and pm-hibernate by hand and the screen went black for 30 seconds or so and then just came right back up.  do these lines contain contradictory instructions?

The wiki said I could name the file "config" or "modules." Does it make a difference?

I should create a file with the name "unload_modules?"

Re: pm-suspend stuff

still no happiness  on resume, usb is dead.

I can eventually add resume hooks or whatever, but first I have to find out what's not coming back up after a resume.   How can I do that?

More generally,  whenever I try to fix something I feel like my failed attempts have left their muddy footprints all over my hard drive.   In this case, I've followed the wiki and done this and that, but  I have reversed some of the changes I made and now I sort of feel like crap is sprinkled around everyplace.

so I guess that leads to a secondary question:

1. What's a good way to keep track of changes, and
2. How should I keep a running record of what I'm doing?

my various journeys could make great wiki pages if I could only remember the steps I took.  Sure I get stuff working, but I lose track of how.

So whatduyou think? git?  even with something like git, I'd need a clean, bare starting point, right?

Re: pm-suspend stuff

If you want to find out what's not resuming after you bring the computer back up - couldn't you just lsmod >> log.log and compare that to the results of lsmod when you come back?

I don't know if that will work AT ALL, but it's a thought.

Re: pm-suspend stuff

good idea.  I just learned that I don't know how to read the output of diff.
I did
lsmod > before.txt
then
lsmod > after.txt
then
diff before.txt after.txt > diffs.txt

and here's what that looks like:

There's a gtk version of kompare, but I can't remember what its name is.

Re: pm-suspend stuff

I think the problem with your diff is that the modules are not listed in the same order.

Also, you only want the first column, the others are not important and muddle things.

You can use 'sort' and 'awk' to fix this, i.e. instead of 'lsmod > before.txt', do 'lsmod |sort|awk '{print $1}'> before.txt'. Then do the same for the after file. (Or you can just 'cat before.txt|sort|awk '{print $1} > beforesorted.txt', etc.)

Also, use the unified format for diff, with 'diff -u'. It makes it easier to figure out the output, I think.

p.s. I know you're supposed to use 'cut' instead of 'awk', but I'm a lazy person who likes to use the command he is most familiar with.

Re: pm-suspend stuff

hmm.

Now when I do pm-suspend my computer reboots.  Why did it start doing that?

Re: pm-suspend stuff

dmesg shows what modules are corrupt...
SUSPEND_MODULES="sr_mod cdrom omnibook sdhci mmc_core evdev ehci_hcd
usbcore fuse vboxdr "
and works great for me...
