Hi, im new to linux performance stuff, and im wondering what's the advantage that 64bit Kubuntu can give, since i checked my Turion64 does support 64bits processing.

- Thx

There are some slight speed improvements as much of the software now is 64-bit compatible. How much of a speed improvement depends on the software, you find it more in software that does float operations, so DSP for audio and video, etc.

Last I checked 64 bit did still have a few kinks to iron out, and there are still places where you need to install 32 bit software(You can do this via emulation libs or a chroot, emulations libs are easy), typically when you have to deal with closed source apps or plugins. Sometimes these can be annoying.

My opinion on it is, for most people go ahead and try 64 bit and see how it works for you. In most cases it will likely work fine, and you would have no problem with it. Eventually you will find the world move to 64 bit, Linux is a bit ahead in this regard compared to Mac OS X and Windows, due to the amount of software that is open source and can easily be compiled for 64 bit.

Answer your question?

I haven't checked recently, but I was under the impression that drivers can still be problematic/spotty in regards to 64bit support.

One of these days I'll try out a 64 bit install.

Yea so do I, but I also keep in mind I run Gentoo, so my experience doesn't necessarily match what most people would consider ideal

Yeah pretty much answered everything. Is just i know there's more questions that i don't know yet. Is kinda troublesome to install Kubuntu on laptops since there's always problematic with hardware, i've been trying to use v6 Kubuntu on this laptop and always reports serial or hascheck is not valid with the CDROM.

I hope this v7 fixed this prob. Also i want to install it on a USB generic storage MP3 player as Kubuntu bootup source. Anyone tried this? Or i can even install it on Memory Stick use on PSP to boot it up? Since PSP is way much faster with USB2.

Any thing i should know and watchout for if i doing that? Linux is sensitive to storage drives i think.

EDIT: One big question, there's Desktop and Alternative Kubuntu to download. Which to choose if i want to use LiveCD. And best if i can hear someone tell me the main advantages of Ubuntu, Kunbutu, Debian, Mandriva and Redhat.

Thank you agian

Serial as in serial number? Where did you download this cd from in that case?

I am afraid I am nto familiar with the term hascheck though, are you referring to the MD5 checksum possibly?

It can be done, but it is a little more advanced to do so, you may want to stick to the regular install for now. However if you wish to try it we can try to help you through it.

Yea, you need to ensure your computer can actually boot off USB. Otherwise you will need a boot disk of some sort to allow this.

Alternative? Meaning the server version? If that is the case go with the desktop version, in fact what you are looking for will likely be the desktop version anyways.

Oi, you are going to open up a can of worms there

At the moment I don't have time to type out a general summary of them, but maybe someone else here can, otherwise I will take a stab at it when I get a moment this evening.

Ow thanks very much Seablade for thoese answers,

Also i've been doing some research on linux distributors. Some made linux like old Apple OS style. Some hybrid of between windows. Than i remembered Mandriva, i did abit research and it seems more like windows style based with Vista theme, i like it very much. So i'm downloading that Free CD tonight and see. Also the kernel is based on Red Hat with KDE4 which sounds like a good thing to me

EDIT: For the USB bootup the idea is to have a 4GB memory to install it on which i have only 2GB. I would really want a linux on USB drive when i got my hands on the latest 8GB stick. And i can't remember the error from the CDROM much since is like more than 6 months ago.

No need to reinvent the wheel. This site

http://polishlinux.org/choose/compar...distro2=Debian

seems very nice to compare this with that. Of course, specific questions, just 'flood' this thread.

ps.: i don't think the "alternate" is the server version of the *ubuntu derivatives. I will check just to be sure.

Yes, the alternate is not the server. Look at http://releases.ubuntu.com/6.06/ under "Alternate install CD" for details.
