superfluous apps won't stay uninstalled??


Hi,
Just a minor problem, but it's pesky and I'd really rather have it resolved. My processor has been overheating of late, and to the end of fixing that I'd like to cut down on its load...
Running ps -A gives me this:
Code:
  PID TTY          TIME CMD

I didn't think I installed KDE initially, as I run WindowMaker and habitually only install the gnome libraries for the sake of making my life easier, but what do I know . I've tried uninstalling KDE via Mandrake's rpmdrake, but each time I think I've uninstalled it I reboot and run rpmdrake...and it's right back in place...I'm very confused, as I really would rather not have KDE (and all its background apps) installed and running...can anyone give me an idea why it won't stay uninstalled??
thanks much
Laura
btw, I've a feeling that quite a few of those aforementioned processes are completely unnecessary...is there a way to tell which programs are calling those processes, or at least find out which ones really are crucial and which ones just feel like running, so I can take their process calls out of the startup scripts?

While 'ps -A' will tell you what's running, 'top' will tell you where all your horsepower is being consumed.

I don't see any KDE stuff in your ps output so my guess is that you're concerned about the processes that start with 'k' and those would be kernel processes which we don't really want to be stopping.

All I can really see as not totally necessary are proftpd and the screensaver but in the background they'll just be chawin' some RAM not really clock cycles. Looks like a pretty clean system.

You should be more concerned about your cooling issue. If you're overheating under this load you'll get stopped cold (er - hot?) when you try to rip an mp3 or render that povray masterpiece.

PLay with the 'top' command (press'h' while it's running to see some options) and see what your CPU load is like.

You're right - it was the processes beginning with 'k' that had me worried.
'top' give me this:

That being the case, and given that it's never done this before, the logical conclusion is that it's a hardware issue...bother. I built it myself, and it's really a pretty decent system, but I'll have to see about putting in another fan or so. Thanks very much for your help! Incidentally, do you know of a good hardware-monitoring app for linux? i.e. one that can give me on-the-fly CPU temps, fan speeds, that sort of thing? I've searched Sourceforge but nothing seems to be what I need :-/.
thanks,
Laura

the lm_sensors project. (google for it) for motherboard/cpu/fan monitoring and ide-smart for S.M.A.R.T. enabled hard drives (most recent drives use smart).

Once you get those runnig there's fancy apps like gkrellm to give a pretty picture of the machine's status.

And as for overheating - if all your stuff is new I'd be looking into a larger heatsink as I doubt another case fan will do you any good.
