What makes you think that KDE uses 480MB?

I guess you'll need to recompile your kernel, mate.

Check the options in
less /usr/src/linux/Documentation/Configure.help
/DMA
(use n to go to the next hit, cursor keys to scroll
up and down a bit, you'll find them all ;})


Cheers,
Tink

linux always tends to use all the memory. What's the point of having it if you don't use it :-)

If you type

free

in a console, what are the results? You'll probably see that most of the memory is cache and buffers.

As for slow - it's something seriously wrong if you can't type on that box. My P III 700 is fine, and I run it on a lot slower than that - celeron 666, P II 350's, etc...

i think i fixed it..

/dev/hda:
Timing buffer-cache reads: 2584 MB in 2.00 seconds = 1292.00 MB/sec
Timing buffered disk reads: 66 MB in 3.03 seconds = 21.78 MB/sec

is that normal?

yeah, you need to recompile your kernel. you may not have support for your motherboard chipset compiled in, and maybe not have dma capability enabled or both.

edit: don't let this confuse you. i was typing it when you were typing the above, i guess.

yeah. that's probably about right.
i'm sorry i started the trouble about kde. it is pretty big though. but i love it anyway. i'm just glad i don't have to use it unless i want to.

I have fedora core 2 with 2.6.5 kernel and kde.
when i bring up kde system guard it shows 426mb of physical memory out of 512.
but when I bring up gkrellm it shows that i have 406 mb free.
so basically what im saying is that system guard is unreliable (duh!)

maybe one is showing 'FREE' Ram.. and the other is showing "AVAILABLE RAM"
you may only have 8 Meg FREE... but as your systems need for ram increaces, linux will start reducing disk cach and other big buffers.

This should explain it.

I had once the same problem, but not that bad. This may sound like a stupid question but just in case, Is your swap partition working, i mean is it in your fstab?
