Holger, Thomas, any reason besides 'historical changes' for this?  

This is only historical reasons. The scheme was in the past to optimize your 
machine to run as quiet as possible. But since we no longer touch the harddisk 
settings the scheme is proper no longer needed.

You can remove the scheme with yast or directly by deleting in /etc/sysconfig/
powersave/

Then wouldn't be better to remove one from the default in order to avoid confusion?

Maybe for 10.1 because I think this is already to late to change the 
documentation of kpowersave and powersave

The only difference between the two schemes are that in powersave the brightness
of the display is set to medium and with acoustic it remains untouched.

So I also think we should remove acoustic scheme _after_ 10.1 as long as there
are no new acoustic features which could be integrated.

I ment after 10.0, of course.

Maybe we add the adjustment for harddisk settings again in acoustic scheme. We
had enourmous problems with one machine with that. If we do not encounter more
problems, we consider adding disk settings again.

i'll take this one, we'll probably keep the acoustic profile but actually change
some settings so that it is different from the powersave setting.

I think Holger has made some cleaning here?

Not yet, but this week I will merge the Acoustic scheme with the new hot AggressivePowersave scheme to a new AdvancedPowersave scheme. Assigning to me...

After more discussions and a new feature which exactly fits into the Acoustic scheme we agreed on keeping it. Additionally, we will have a new scheme AdvancedPowersave which will get a very special handling in our clients.

Seife, do you want to reenable additional harddisk settings in the Acoustic scheme? Because of many upcoming questions about harddisk settings, I would say 'yes'. Maybe we should use only slight settings for that.

yes. I also wanted to untangle the disk settings from the laptop-mode etc. I will do this and then set reasonable harddisk settings in the different schemes.

the acoustic scheme now has the following differences:

-DISK_ACOUSTIC="performance"
+DISK_ACOUSTIC="quiet"
-DISPLAY_BRIGHTNESS="med"
+DISPLAY_BRIGHTNESS="ignore"

and we reenabled disk settings per default again. Although the difference is very small - the acoustic scheme actually is different again :-)
