Hi

How can I find out which processes are running in the background and stopping my machine from sleeping?

I've outlined all the problems I'm having with my new Canon LiDE 30 scanner on the Peripherals forum (and there are dozens of other people with the same problems on this and other forums) but basically, the needless button drivers are known to stop the machine sleeping. The thing is, I've removed these files and my mac still has insomnia. They aren't in CFMSupport or listed as start-up items. I've experimented with removing other files in CFMSupport and I get to the point where the scanner no longer works.

Surely SOMETHING is causing the sleep problems - is there some way of discovering what? Would the Process Viewer be the place to look and can anyone offer advice on how to interpret what I find there.

Many thanks - this is my fourth day trying to sort out the problem.

[drissa]

Here's the latest, in case anyone is still following this one:

Unplugging the scanner's USB lead allows my machine to sleep. This isn't the most elegant solution and I'd rather get to the bottom of the problem.

Other than the known button files, what else could be going on between machine + scanner to cause the sleep problems?

[Mithras]

Have you looked at ProcessViewer? Try posting the output from that (or ps auxww in the Terminal) and someone can help you.

[pat++]

It may be caused by a bad kernel extension/driver...

Open Terminal, and try :

kextstat | grep -v "com.apple" | grep -v Index

It should list all installed kernel extensions which are not apple's. Let's say :

11 10 0x124ec000 0x9000 0x8000 com.company.faultly.driver (1.2) <4 3>

unload the kernel extension with :

sudo kextunload -b com.company.faultly.driver

then, go in /System/Library/Extensions and find the corresponding kernel extension.

move the bad kernel extension to your homedir to disable it permanently :

sudo mv /System/Library/Extensions/Faultly.kext ~myusername/

Hi

I can't copy and paste from Process Viewer. I tried the 'ps auxww' command in Terminal and received an enormous list of gabble that I honestly can't believe anyone would want to pick through.

Sorry Pat, but you're speaking Greek to me. I tried the same - copying the commands into Terminal - but it wasn't having it.

Can anyone give any hints as to what I might be looking for in the Process Viewer. This is truly driving me batty and I'm planning on chewing my own legs off.

Bear in mind that I'm a relative novice and certainly don't delve into the arse-end of my machine with much confidence.

Thanks.

Let's do it step by step. Copy/Paste this line in Terminal and post the output here... I'll see if there is something suspicious...

kextstat | grep -v "com.apple" | grep -v Index

(make sure your scanner is connected to the Mac)

Notice that if you don't get any output, this is because there is no third party kernel extension installed (ps auxww will be helpful in this case, post the output here)... (but I guess you'll find something related to Canon...)

[drissa]

Hi Pat

The first line you suggested responds with 'command not found'. The second produces the following. It's very good of you to help out - much appreciated. Take a deep breath...

It seems that your are using an alcatel modem... Is this a USB one? If this is the case, does your computer go to sleep if you are not connected (and the modem is not plugged on the Mac, but the scanner is).

Concerning the first line, try this, it should work :

/usr/sbin/kextstat | /usr/bin/grep -v "com.apple" | /usr/bin/grep -v Index

(make sure your scanner is connected to the Mac)

and post the output here.

[drissa]

Hi Pat

No, the Alcatel USB modem was evil (kernal panics, etc) - I have an ethernet router.

I pasted the line into Terminal -

Welcome to Darwin!
[localhost:~] benjohns% /usr/sbin/kextstat | /usr/bin/grep -v "com.apple" | /usr/bin/grep -v Index
/usr/sbin/kextstat: Command not found.
[localhost:~] benjohns%

The scanner is hooked-up.

Maybe I'm doing something wrong?

Thanks

[drissa]

Something I've just noticed that might be helpful.

Having had the scanner unplugged, I plugged it back in to try the previous Terminal command and when I tried to put the machine to sleep afterwards, it worked.

I woke it up and the scanner was being recognised in Elements 2. However, an attempt to then make the machine sleep again failed.

Maybe this is telling of the nature of the problem?

It's weird... Which version of OS X do you use ? is this 10.1 ? or 10.2 ?

[pat++]

I just found that if you are running 10.1, you should replace kextstat with kmodstat...

try :

/usr/sbin/kmodstat

and post the result here... hopefully it will work this time (if you are running 10.1)

[KidRed]

I used to have the Canon lide 30 and my QS wouldn't sleep either. However, I have sin ce disconnected it and repalced it with an HP all-in-one and my QS still won't sleep by timed energy saver. It will sleep if I put it to sleep and no probs waking. However, if i set the machine to go to sleep in 20 minutes, the monitor will but not my QS.

[drissa]

Sorry - I neglected to say that I'm still crawling behind on 10.1.3

Welcome to Darwin!
[localhost:~] benjohns% /usr/sbin/kmodstat
kmodstat: unable to get kernel task port: (os/kern) failure
kmodstat: Are you running as root?
[localhost:~] benjohns%

Hmmmmm...

As I mentioned before, I've been unplugging the scanner to put the machine in sleep. When I wake the machine up and reconnect the scanner, the machine will sleep. It's only once I've opened the scanner interface in P/shop Elements that the sleep function is disabled.

This tells me - and it's guess work - that the problem is not a process running in the background, or at least one that is only triggered when the scanner is called up. But, like I said, I'm a novice. And an increasingly frustrated one too...

[Powaqqatsi]

Try this:

Code:
sudo /usr/sbin/kmodstat | /usr/bin/grep -v "com.apple" | /usr/bin/grep -v Index

and give your admin password if it asks for it.

[pat++]

oops. I forgot 'sudo' at the begining of the command to execute kmodstat as root :

sudo /usr/sbin/kmodstat | /usr/bin/grep -v "com.apple" | /usr/bin/grep -v Index

<enter your password when prompted>

and post the result.

I believe as you said that this is not a process, but rather the kernel extension/driver of the scanner which causes the sleep problem... we'll try to disable it and see if it fix the issue.

[drissa]

Thanks Pat -

hmmm... just to make sure we don't miss anything, try this simplier command (sorry for doing things step by step like this, but I don't have 10.1 to see what the output should look like) :

sudo /usr/sbin/kmodstat
(enter your password if required)

(make sure the scanner is plugged-in, and try to use it once so that the problem is supposed to occure before entering the command above)

and post the whole output once again...

Okey, it seems that everything is fine... no third-party drivers installed. I'm afraid it's a bug in Apple's own driver... As you are running a very old version of OS X, I would suggest to update to 10.1.5 at least (it's free, get the update from Software Update in System Preferences, or from apple.com), or better, switch to Jaguar (or Panther when it's available). 10.1.3 about 1.5 years old, they problably have fixed this issue in the meantime...

[KidRed]

10.1.3? Wow that is old. Not sure the version, but having a USB hub connected caused a few issues.

[drissa]

Many thanks Pat. I know I'm well behind with OS X - really, I've been waiting until I can buy a new drive, get the partition thing sorted and get Jaguar all in one swoop.

[fugu13]

You can download the 10.1.5 update for free in software update. It fixed a lot of USB related issues.

[Stephen Haunch]

Take a look at your login items, is there one for your scanner (which detects when you press a button)? My iMac wouldn't sleep after I installed my Canon scanner software but removing the login item solved the problem.
