[Powertop] Powertop --claibrate doesn't run

[-- Attachment #1: Type: text/plain, Size: 467 bytes --]

When I run the command "powertop 
--calibrate --debug" it turns my screen black but then does nothing 
(even if I leave it for 30 minutes) and when I touch the mousepad, it 
shows the command simply returned with no output like this:


myuser:~>kdesu /usr/sbin/powertop --calibrate --debug 
myuser:~>


I'm using:
openSUSE 12.2
KDE 4.8.5
Kernel: 3.4.11 (64bit)
8GB RAM (6.5GB free)
Intel i5 1.7 quad core


How do I fix this? What could be wrong?

things you can try to see if stuff happens:

0) echo $? -> inspect the return value
1) run `time powertop --calibrate --debug` to see if it just doesn't
return really fast
2) run it under strace...
3) inspect if it writes the powertop data to /var/cache...

 sudo gdb /usr/sbin/powertop
 run --calibrate --debug

Thanks!

That's helpful for a lot of things!

I believe I have figured otu the issue:

It appears there was a bug in powertop 2.0:

https://lists.01.org/pipermail/power...ay/000035.html

Upgrading to 2.2 appears to fix the problem (uninstall powertop 2.0 first):

Code:
myuser:~>wget download.opensuse.org/factory/repo/oss/suse/x86_64/powertop-2.2-1.1.x86_64.rpm
myuser:~>sudo rpm -i powertop*
