A couple questions

Heeey,

i have a relatively fresh install of mandriva one 2008, got a few questions:

shutdown button in kde .. all i can d o _straight_ from kde is log off. it then takes me to the kdm login screen from where i can shutdown. is there any way to add a shutdown icon to my kde, instead of having to log off and then do it?
hostname - i'm still the stock 'localhost', i tried setting the name via the 'hostname' command, like i would do on other distros, but it's reset to 'localhost' after reboot
cpufreq fails - since this is a laptop, i'd sure like to do some powersaving - but when i select any other power scheme ('policy') i get the small popup message that cpufreq policy could not be set - no more info. what's up with that?
hdparm - back on slackware i used to issue a hdparm -S1 /dev/hda to save up some battery - i could do the same here, but since there's a nifty gui for powersaving option, i was wondering if it could be enabled in some other way?

so much for now, more may follow

I guess you can make a launcher which executes the shutdown command... It's a puzzle that you don't have "shutdown" as an option along with "hibernate" and "sleep". Using the little red button in the right-hand corner.

Use the "Set up a new Network Interface" module and simply re-configure the existing interface

huh... check that cpu frequengy scaling is enabled in BIOS. Try noapic, nolapic on the kernel line.

You want the HDD to sleep if it's inactive for 5mins? Nah - that's the way you do it all right.

I was thinking this is a permission issue - since i can't even shutdown -h now without giving the root password. even if i make a launcher, i still have to enter the root password. which is just as inconvenient as going through kdm

done, i must've overlooked the hostname option previously, thanks

noapic - changes nothing, plus the system hung when shutting down
nolapic - wont boot
cpufreq in BIOS - unfortunately, no such option in there

when i click 'configure KPowersave' and go under 'scheme settings' the "CPU Frequency Policy" is not 'active' (grey font) and it says "not supported" next to it. pretty straightforward, but .. how come Windows manages to adjust CPU speed, on exactly the same cpu (Celeron M - i know, i know, i know, i needed a cheap 2nd laptop)?

Possibly the cpu scaling is not supported in bios but windows has an extra tool for it, has an additional option in the DSDT (if windows then enable freq scaling)...

You can spoof the OS version your laptop is compensating for on the kernel line and see.

OR: windows is lying... it has the app, and it is activating, but it doesn't do anything. After all, how would you tell?

To setup the system to shutdown you need to go into the Control Center/system admin./login manager to change the settings.

You need root privileges to do this.

To set your hostname go to Configure Your Computer/Network and Internet/Host Definitions.

There you should be able to set the hostname you want.

Mine looks like this....
127.0.0.1 GlennsPref.lan GlennsPref localhost

You can check after a reboot here.. /etc/hosts

The system needs to be rebooted to resolve any hostname discrepancies.

Cheers, Glenn
