    [SOLVED] Debian rocks on 32 MB RAM -- please help me.

    After seeing the performance of Debian on my Laptop I installed it on my old desktop Pentium MMX 200 MHz 32 MB RAM (not expendable). I tried to install and run xorg but it did not work for my old monitor. I tried couple of Modelines in xorg.conf but could not succeed. Finally I installed xvesa and running it as root with following command.
    # xinit -- /usr/X11R6/bin/Xvesa -screen 640x480x16 -mouse /dev/ttyS1
    I have installed IceWM and created .xinitrc so that it starts with the above command.
    Following is the output of free -m
    Total used free
    Mem: 28 26 1
    -/+ buffers/cache 10 17
    Swap 243 0 243

    From ps aux I find that I could save on the memory by stopping tty2 tty3 tty4 tty5 tty6.

    Please tell me how to do this.

    I could also succeed to run IceWM on xorg on this machine.
    $ free -m
    Total used free
    Mem: 28 26 2
    -/+ buffers/cache 11 17
    Swap 243 1 243

    There is hardly any difference in Xvesa and xorg (only 1 MB swap being used).

    $ ps aux | wc -l
    31

    Debian really rocks on 32 MB RAM.

    I have also configured the legacy ISA sound card. Read it here.

    I commented the getty lines for tty2 to tty6 in /etc/inittab

    you could have just gone dsl linux. i would probably also have made the swap bigger, say 512 or 1g.

    I generally use DSL on the desktop but experiment with others. I was using Ubuntu Dapper Drake with Xvesa on it which is now replaced by Debian Lenny with Xvesa.

    I did something similar with a 64 MB laptop a while back. It is very cool.

    One of the reasons, by the way, that DSL performs slightly better on ancient hardware than even a stripped-down Debian is the 2.4 kernel. The difference in memory usage is negligible by modern standards, but for a 32 MB machine it does make a difference. You might try compiling one of those to get even more out of this old box.

    I don't think compiling the Kernel is necessary because Debian net-install automatically installed 486 Kernel on the desktop and 686 Kernel on the Laptop.

    Thanks, but one of my friend already tried to add 32 MB. In fact it is already present in the hardware but does not show up in memory. If you know some thing about hardware please tell me how to make it work.

    I guess you didn't understand what I meant: the 2.4 kernel uses slightly less memory than the 2.6 kernel. Debian only uses the 2.6 kernel, therefore recompiling an older kernel might give you a slight performance boost.

    No, it's not necessary, it was just a suggestion.

    Umm... What is the bare minimum hardware specs to run a basic command line Linux 2.6 system?
