This is really freaking weird.  I have a friend who's running SuSE 6.1
on a PPro 200 with 32M RAM, and he's having no problems running KDE or
Netscape or anything in particular.  HOWEVER, he did have a strange
problem in that the swap space he enabled wasn't recognized on the first
bootup.  Enter "free" at the command prompt, and make sure you see a
line that says something about swap space.  If that isn't there, you may
have to manually enable the swap.  (You do have a swap partition,
right?  If not, make one, and the speed will go *way* up when you enable
it...)

If that isn't the case, there are several things you can do to reduce
memory usage.  Take a look at the output of "ps auxw | more" and see
what all's running.  Chances are there are a lot of things that were
enabled by default that you don't need, like sendmail and portmapper and
possibly Apache.  Also, the more virtual consoles you have enabled, the
more memory you use for that.  I tend to use no more than 3 virtual
consoles, so I commented out the lines that start VCs on tty4, tty5, and
tty6 in /etc/inittab.

Caldera OpenLinux 2.3 RAM requirements?

You obviously have not read the update, or
visited the site...

The Caldera 2.3 disk failed to install the
proper Swap info to the /etc/fstab file.  You
will have to manually type it in your self...

you can go to support site at

http://support.calderasystems.com/caldera?faq

here's the excerpt from the help page...

[---begin here ---]

 I have just installed a 2.3 system it's seems slower than a 2.2 system I
installed on a similar box. (It has the same processor and an equal
 amount of memory.)

 Solution:
 We have identified a problem with lizard. While it creates the swap
partition, on some machines it does not set up the system to use the swap
 partition correctly. In order to work around the problem you need to modify
your /etc/fstab file.

 To verify your system has this problem run "free". The output will look
simular to the following:

 total used free shared buffers cached
 Mem: 63160 61388 1772 18808 12560 28748
 -/+ buffers/cache: 20080 43080
 Swap: 0 0 0

 From this we can see that there is no swap allocated.

 To resove the problem first identify what partition is allocated as your swap
partition. To do this login as root and run the following
 command:

 fdisk -l

 (note: in the above command the switch is the letter l as in list.)

 The output should be something simular to this:

 Disk /dev/hda: 255 heads, 63 sectors, 524 cylinders
 Units = cylinders of 16065 * 512 bytes

 Device Boot Start End Blocks Id System
 /dev/hda1 * 1 26 208813+ 6 FAT16
 /dev/hda2 27 276 2008125 83 Linux
 /dev/hda3 277 292 128520 82 Linux swap

 The swap partition is ID 82 and labeled "Linux swap". In this case it is
device hda3.

 Now using vi, or your perfered editor, edit /etc/fstab and add the following
line as the second line. (Usually the root partiton mount statement
 is first.):

 /dev/[swap_part] swap swap defaults 0 0

 Replacing [swap_part] with the divice that matches your swap partition.

 The edited file should look something like this:

 /dev/hda2 / ext2 defaults 1 1
 /dev/hda3 swap swap defaults 0 0
 devpts /dev/pts devpts gid=5,mode=620 0 0
 /proc /proc proc defaults 0 0
 /dev/fd0 /mnt/floppy auto defaults,user,noauto 0 0
 /dev/hdc /mnt/cdrom iso9660 ro,user,noauto 0 0

 After saving you new fstab file you can enable the swap partition with the
follow command:

 swapon /dev/[swap_part]

 Replacing [swap_part] with the divice that matches your swap partition.

 Now you can run "free" and see that the swap space is available for use.

 total used free shared buffers cached
 Mem: 63160 61548 1612 18808 12644 28748
 -/+ buffers/cache: 20156 43004
 Swap: 128516 0 128516

Your system is hitting the swap file, 32MB would be fine without KDE but
with it more would be better.

Thank you all for the replies; indeed the swap space was not activated -
after activation with "lisa --swap", everything runs just smooth.

Thanks again,

1. Caldera Openlinux and 2.3.xx

Hi,
    I am running (Caldera's) OpenLinux 2.3 (kernel version 2.2.10), and I
was wanting to try to upgrade to the 2.3.51 kernel.  I know this kernel
isn't a stable kernel yet, but I would still like to try and run it.  I
unzip the source file and use all the make commands (make xconfig, clean,
bzImage, modules, modules_install).  All this is done without any errors.  I
then configure lilo.  My problem is when I try to boot the new kernel
nothing happens.  I went to Caldera's site and they said to upgrade the
kernel use rpms, only I don't think rpms for 2.3.51 exist.  Is it possible
to upgrade the kernel without rpms?  Thank you for your help.
