Possible to disable HAL, powersaved, dbus on OpenSuse 10?
Hi I'm running an older server and actually I'd like to disable all services I dont absolutely need.... I saw that by default HAL, powersaved and dbus are running on my system. Is it save to disable them or are these essential system services? The computer isn't a laptop so i dont know if i really need powersaved ? HAL and DBUS is something new to me, i dont have them on my Suse9.0 system -- are they really needed? I've already disabled subfs and since the computer is a server i dont need any hotplugging, usb or something like that for which I guess HAL could be used..... Thanks a lot! Matt

powersaved is save to disable.

Do you have frequency scaling?

Yes.

It also keeps an inventory of hardware, I would leave it on, Andreas -- Andreas Jaeger, aj@suse.de, http://www.suse.de/~aj SUSE Linux Products GmbH, Maxfeldstr. 5, 90409 Nürnberg, Germany GPG fingerprint = 93A3 365E CE47 B889 DF7F FED1 389A 563C C272 A126

eerm.. dunno? It's a Pentium III, 1.2GHz...?

Yes.
Okay then, thanks for clarification :) Matt

Guess not but check the logfiles and the powersave command, Andreas -- Andreas Jaeger, aj@suse.de, http://www.suse.de/~aj SUSE Linux Products GmbH, Maxfeldstr. 5, 90409 Nürnberg, Germany GPG fingerprint = 93A3 365E CE47 B889 DF7F FED1 389A 563C C272 A126

When i issue: # powersave -c Speedstepping is not supported. So that means i can safely disable powersaved ? Thanks Matt

Yes, you can, Andreas -- Andreas Jaeger, aj@suse.de, http://www.suse.de/~aj SUSE Linux Products GmbH, Maxfeldstr. 5, 90409 Nürnberg, Germany GPG fingerprint = 93A3 365E CE47 B889 DF7F FED1 389A 563C C272 A126

It also keeps an inventory of hardware, I would leave it on, What might cause an apparent system lockup when HAL is enabled? While installing 9.3, I had to completely bypass the hardware detection phase because the system froze on me every time when the detection routines kicked in. I do not recall seeing any indication of the source of this behaviour. After 9.3 was successfully installed on the system, it still froze on every boot until I started the rescue system and disabled HAL. Once the sysconfig was updated during YOU, after which HAL was re-enabled; I had to fire up the rescue system again and disable it because the system was locking up again.
The only thing I can think of that might be the cause of this behaviour is an ISA SBAwe32 sound card, which has subsequently been replaced (I got tired of seeing all those "kernel tainted" messages, but those are still with me because I now have an ATI chipset on my new video card :) ). All of this happened before I replaced the sound card, and I haven't had the courage to re-enable HAL to see if this was indeed the cause. The rest of the system is pretty vanilla: 2 IDE drives, 2 ATAPI devices, PCI network card, PCI video card (since replaced with an AGP card), USB disabled in the BIOS, no RAID/SCSI/PCMCIA, no onboard devices that might conflict with an installed card. I emphasize "apparent" above, since I have never had the patience to just walk away and see what happens. I didn't think that was the way an OS install was intended to happen, and ignoring all hardware during install/disabling HAL at boot gave me a system that works. I do see the occasional whining message about some HAL component not being available (eg. during KDE startup), but otherwise am having no problems.
